Note 2: The Optim trip unit samples either neutral current or ground current, depending on its configuration. The Percent THD values can be used to determine which currents were sampled. Non-sampled currents will have a Percent THD value of -3. For more information on the Percent THD calculation, see Note 3 below.

Note 3: All Percent THD values are set to -3 (indicating not available) upon powerup. Following each waveform capture, the Percent THD values corresponding to the sampled currents are then calculated. If the Optim aborts a waveform capture, those Percent THD values (corresponding to the sampled currents) are set to -2 (indicating invalid), If the measured current is less than 2% of rating, the Percent THD values (corresponding to the sampled currents) are set to -1.

Note 5: To assure the uploaded sampled data and the uploaded harmonic component values are from the same sampled waveform, the INCOM network master should read the data header before starting and again after completing the upload, and should verify the waveform capture index did not change during the upload.

Receive INCOM Address Description (3 D 9)


Byte1 INCOM Address – MSB

Bit Definition B3-B0 bits 11-8 of the INCOM address

B7-B4 0100 = 1,200-baud ASK modulation

1101 = 9,600-baud FSK modulation

Byte2 INCOM Address – LSB (bits 0-7 of the INCOM address)

2 Byte0 Checksum – Low byte

Byte1 Checksum – High byte

Byte2 One's complement of the low byte

Note: The Digitrip Optim responds to the first data messages with a (3 1 0) Acknowledge message containing the old (current) address. The Optim responds to the second data message with one of the following messages:

Response Definition

(3 1 0) ACK containing new address The new address was accepted. (The checksum was valid.) The Optim will proceed with saving the new address in NVRAM.

(3 1 A) NACK containing old address The new address was not accepted due to a communications checksum error.

(3 1 B) NACK containing old address The new address was not accepted due to an invalid baud rate/modulation request.

Note: Following the Receive INCOM Address command, the Digitrip Optim will save the new address to NVRAM. This may take up to 250 milliseconds.

Note: If the Digitrip Optim doesn’t respond after a new address is downloaded, the Optim may have experienced a problem with storing the new address in NVRAM. If this occurred, the Optim’s INCOM address and baud rate will revert to their default values (Address=0FFE and baud rate=9,600 baud).

Byte2 1’s Complement of LSB of checksum

Note 1: This is a read-only setpoint that is not user-selectable.

Note 2: The Rating Plug is a read-only setpoint that is user-selectable only by changing the Rating Plug at the device.

Note 3: At least one of Instantaneous action or Short Delay action must be set to TRIP.

Note 4: Ground Delay action may not be changed if it is set to 1=TRIP; Ground Delay action may not be changed if it is set to 4=NONE; Ground Delay action may be changed from 0=OFF to 2=ALARM and vice versa.

Note 5: The acceptable values of Pickup current mantissa are bounded. Each setpoint in Message 13 represent a variable upper-bound of a mantissa for a given Pickup current associated with an overcurrent trip function (e.g. SDPU mantissa limit is the upper bound for the SDPU mantissa setpoint). Pickup mantissa values exceeding an associated limit will be rejected by the Optim per Note 7 below.

Note 6: When LDT slope = 4 (I4T), SDT slope must be set to 0 (FLAT).

Note 7: The device performs range checking on the setpoints as they are downloaded. If a setpoint is deemed valid, the device responds with a (3 1 0) ACK message. If an out-of-range setpoint value is detected, the device responds with a (3 1 B) NACK message, discards previously received setpoints, and will cease accepting additional setpoints until the (3 F 9) command is re-sent.

Note 8: The device responds to the last data message with one of the following messages:

Response Definition

(3 1 0) ACK The new setpoints were accepted (the checksum was valid). The device will proceed with saving the setpoints to NVRAM (i.e. EEPROM).

(3 1 A) NACK The new setpoints were not accepted due to a communications checksum error.

Note 9: Following the Setpoints download, the device will save the new settings to NVRAM. This may take up to 2 seconds. During this time period, the device will respond to setpoints requests with a “Buffer Not Yet Available” (3 1 5) NACK.

Note 10: It is recommended that the INCOM master read the device setpoints subsequent to their download. A check should be made to verify the new settings match the downloaded values.




Note 11: The Ir mantissa lower-bound is dependent upon the Frame Size (see Message 2, Byte0) and Comm Version [See (3 0 0) Fast Status]:

Comm Version = 1: Ir mantissa lower-bound = 50 for Frame Sizes

2,3,6,7,10,11,12; for all others Ir mantissa lower-bound = 40.

Comm Version > 1: Ir mantissa lower-bound = 40 for all Frame Sizes.

Note 12: The GDPU mantissa lower-bound is dependent upon the Frame Size (see Message 2, Byte0): GDPU mantissa lower-bound = 24 for Frame Sizes 2,3,6,7,10,11,12; for all others GDPU mantissa lower-bound = 20.

Note 13: This setting applies only to Comm Version = 2 or greater; this setting is undefined for all others.

The Phase A pole identifier setpoint is used to designate which pole is connected to the Phase A conductor:

Message 14, Byte0, Bit0 = 0 identifies breaker terminal #1 (the breaker line side left pole) as Phase A.

Message 14, Byte0, Bit0 = 1 identifies breaker terminal #5 (the breaker line side right pole) as Phase A.

For example, for a normal vertically mounted breaker, the Phase A pole identifier should select terminal #1 as Phase A (Bit0 = 0).

For example, a horizontally mounted breaker (Line side to the left) should select the terminal #5 as Phase A (Bit0 = 1).



Enter Test Mode (3 F A)


Byte1 Test Type 0=Phase Current, 1=Ground Current

Byte2 Test Action 0=NO TRIP, 1=TRIP

2 Byte0 Trip Test Current mantissa (per unit)

For φ current, range is 10-100 with an implied

decimal point (1.0 – 10.0)

For Gnd current, range is 2-20 with an implied

decimal point (0.2-2.0)

Byte1 Trip Test Current exponent = -1

Note 1: The Digitrip Optim performs range checking on the test parameters as they are downloaded. If a test parameter is deemed valid, the Optim responds with a (3 1 0) ACK message. If an out-of-range test parameter is detected, the Optim responds with a (3 1 B) NACK message and ceases to accept additional test parameters until the (3 F A) command is resent.

Note 2: The Digitrip Optim will enter the Test Mode after the last message. The test may take significant time to complete or may never complete depending upon the Test Type, Test Mode parameters and actual electrical system conditions.



Transmit INCOM Address and Baud Rate (D F F) The format of the Transmit INCOM Address and Baud Rate command message is:

C/D =1

INST =D

COMM =F

ADDRESS =Reserved (don’t care)

Note: The Digitrip 520MC trip unit responds to the first data messages with a (3 1 0) Acknowledge message containing the old (current) address. The Digitrip 520MC responds to the second data message with one of the following messages:

Response Definition (3 1 0) ACK containing new address The new address was accepted. (The

checksum was valid.) The Digitrip 520MC trip unit will proceed with saving the new address in NVRAM.



Note: Following the Receive INCOM Address command, the Digitrip 520MC trip unit will save the new address to NVRAM. This may take up to 250 milliseconds.

Note: If the Digitrip 520MC trip unit doesn’t respond after a new address is downloaded, the Digitrip 520MC trip unit may have experienced a problem with storing the new address in NVRAM. If this occurred, the Digitrip 520MC trip unit’s INCOM address and baud rate will revert to their default values (Address=0FFE and baud rate=9,600 baud).

Communications Protocol for the Digitrip II T700 and T800

COMMUNICATIONS PROTOCOL – DIGITRIP II T700 AND T800 The Digitrip T810 and T910 trip units are backward-compatible with versions T700 and T800 of Digitrip II. Thus, the T810 and T910 responds to all of the commands described in this section. The T810 and T910 also responds to the commands described in Sections 202 and 203. This was done for renewal parts considerations. New INCOM system communications software should utilize the commands outlined in sections 202 and 203.

These two setpoints determine two intermediate terms that are used to calculate the Ground Fault Pickup and Ground Alarm Pickup.

The Ground per unit value and GDPU mantissa upper limit are defined as follows:

If Ext Ground Scale Factor is set to 0 AND

the Ground Current Source is set to 1, then



If the Ground Current Source is set to 0 then,

Ground per unit value = In and GDPU mantissa upper limit = GDPU mantissa maximum.

Otherwise,

Ground per unit value = Ext Ground Scale Factor * 10 and GDPU mantissa upper limit = 100. (Note: For Ext Ground Scale Factor = 2 ONLY.) Ground per unit value = Ext Ground Scale Factor * 10 * 1.25. This represents a scale factor of 25.

32 Byte0 Frequency Values = 50 (50Hz), 60 (60Hz)

Note: The Frequency setpoint is used to program the trip unit to match the system frequency. If this Frequency setting is changed, the Over/Under Frequency Trip and Alarm settings (Shown in messages 39, 40, 43, and 44) that are not set to OFF must also be changed. If the Frequency setting is changed from 50 (50Hz) to 60 (60Hz), any Over/Under Frequency Trip and Alarm setting that is enabled will be changed by adding 1000 to it (5100 becomes 6100). Conversely, if the Frequency setting is changed from 60 (60Hz) to 50 (50Hz), any Over/Under Frequency Trip and Alarm setting that is enabled will be changed by subtracting 1000 from it (6200 becomes 5200).

Byte1 Primary Voltage Rating – LSB Range: 1000 to 17000v Byte2 Primary Voltage Rating – MSB step = 1volt Note: The preferred format for displaying this parameter is: VT Ratio = Primary Voltage Rating : Secondary Voltage Rating

The Primary Voltage Rating setpoint determines the external voltage transformer and is used to determine the Over/Under Voltage Trip and Alarm settings shown in messages 37, 38, 41, and 42. Since the Over/Under Voltage Trip and Alarm settings are entirely dependent upon the Primary Voltage Rating, any change made only to the Primary Voltage Rating setpoint must result in also turning the Over/Under Voltage Trip and Alarm settings to OFF or 0.

Note 1: Waveform buffer status bits can be used to determine which types of buffers are available for a specific event:

♦ Bit 0 set indicates that the INCOM master can request the Time-Stamped Event Buffer via the (3 F B) command.

♦ Bit 1 set indicates that the INCOM master can request the Waveform Sampled Data buffers via the (3 F B) commands

♦ Bit 2 set indicates that the INCOM master can request the Frequency Analysis Data buffers via the (3 F B) commands.

Note 2: The Frequency Analysis data packets (3 C F) N=05xx01 are available only for the following causes of capture:

♦ Local Front Panel

♦ IMPACC

♦ Auto

Note 3: The Digitrip 1150 does not lock Waveform buffer #0. In order to assure that the uploaded sampled data and the uploaded harmonic component values are from the selected sampled waveform, the INCOM network master should read the waveform data header at the start and again after completing the upload, and should verify the waveform capture index and time of capture did not change during the upload. (Alternatively, the Time-Stamped Event Data Buffer may be read to verify these parameters.)

Note 1: The Digitrip 1150 will sample either neutral current or ground current, depending on its configuration. The Sampled Signals (Message 16 Byte0) values can be used to determine which currents were sampled.

Note 2: Percent THD values are calculated for 64 sample waveforms only. All Percent THD values are set to -3 (indicating not available) upon powerup. Following each waveform capture, the Percent THD values corresponding to the sampled currents are then calculated. If the Digitrip 1150 aborts a waveform capture, those Percent THD values (corresponding to the sampled currents) are set to -2 (indicating invalid), If the measured current is less than 15% of rating, the Percent THD values (corresponding to the sampled currents) are set to -1.

Upon receiving this command, the Trip Unit also zeroes the "Network Master Node Address" field in the Waveform Summary buffer (3 C F) N=000001 Message 2, and resets the "Waveform Data Upload in Progress" bit in the Waveform Summary Buffer Message 2. Also, see "Download Waveform/Event Buffer Request (3 F B).”

Byte1 Checksum – High byte


Note: The Digitrip 1150 trip unit responds to the first data messages with a (3 1 0) Acknowledge message containing the old (current) address. The Digitrip 1150 responds to the second data message with one of the following messages:

Response Definition

(3 1 0) ACK containing new address The new address was accepted (the checksum was valid). The Digitrip 1150 trip unit will proceed with saving the new address in NVRAM.



Note: Following the Receive INCOM address command, the Digitrip 1150 trip unit will save the new address to NVRAM. This may take up to 250 milliseconds.

Note: If the Digitrip 1150 trip unit doesn’t respond after a new address is downloaded, the Digitrip 1150 trip unit may have experienced a problem with storing the new address in NVRAM. If this occurred, the Digitrip 1150 trip unit’s INCOM address and baud rate will revert to their default values (Address=0FFE and baud rate=9,600 baud).



Receive Setpoints Description (3 F 9) The Receive Setpoints (3 F 9) always starts with an upload of the setpoints from the Digitrip 1150 trip unit as outlined in Setpoints Buffer Description (3 C 9). Setpoints are sent to Digitrip 1150 trip unit in same form that they are uploaded.

Byte2 One’s complement of LSB of checksum

Note 1: The Digitrip 1150 trip unit performs range checking on the test parameters as they are downloaded. If a test parameter is deemed valid, the Digitrip 1150 trip unit responds with a (3 1 0) ACK message. If an out-of-range test parameter is detected, the Digitrip 1150 trip unit responds with a (3 1 B) NACK message, and will cease accepting additional test parameters until the (3 F A) command is re-sent.

Note 2: The Digitrip 1150 trip unit will enter the Test Mode after the last message. The test may take significant time to complete or may never complete depending upon the Test Type, Test Mode parameters and actual electrical system conditions.

Note 3: The Digitrip 1150 trip unit setting for Trip Test Current mantissa has the following ranges (in per unit):

♦ Phase Current range is 4 to 140 (Trip Test Current per unit range of 0.4 to 14.0 PU).

♦ Ground Current range is 1 to 20 (Trip Test Current per unit range of 0.1 to 2.0 PU).

Byte2 Complement of checksum – LSB

Note: The Digitrip 1150 Trip Unit indicates that it has accepted the Download Waveform Buffer request by responding with an ACK message after each message received. Upon accepting a (3 F B) request, the Digitrip 1150 Trip Unit will set the "Waveform data upload in progress" bit in the Waveform Summary Buffer (3 C F) - N=000001 Message 2, indicating that an INCOM waveform request is in progress. This flag is cleared when the Digitrip 1150 Trip Unit receives the (0 1 5 slave action command. If the Digitrip 1150 Trip Unit receives another (3 F B) request and an INCOM waveform request is in progress (flag set), the Digitrip 1150 Trip Unit will respond to the last message with a "Buffer Not Available" response.

Note: The Digitrip 1150 Trip Unit does not support Node address of Network Master.

Note: Upon accepting a (3 F B) waveform/event buffer request the Trip Unit will "lock out" other requests for the selected waveform. This lockout will be cleared when the Trip Unit receives the (0 1 5) Slave Action command. The Trip Unit will clear the lockout automatically if no (3 F B) requests are accepted for 5 minutes.

Note: In order to assure the uploaded sampled data and the uploaded frequency analysis values are from the selected sampled waveform, the INCOM network master should read the waveform data header at the start and again after completing the upload, and should verify the waveform capture index did not change during the upload.

FP-5000 Feeder Protection Relay Counters Buffer – History Log Buffer (N=000033H) This buffer supports the transmission of historical information maintained by the device. This information includes number of hours of operation, number of times powered up, number of trips, number of breaker operations, and number of accumulated interrupted amps. This buffer supports the Total History Log and the Breaker History Log. The accumulated interrupted amps are 32-bit unsigned integers; the other counters are 16-bit unsigned integers.

The Total History values are reset when the device receives a Reset Total History Log Slave Action command (3 D 0>03:00:0x0E). The Breaker History values are reset when the device receives a Reset Breaker History Log Slave Action command (3 D 0 ->03:00:0x0F).

Note: The number of Frequency and Power Trips are only available for Comm Version 2 and higher.

Note: The Trip Log Index is a 16-bit value with the Trip Buffer (0-15) in the least significant nibble.

Note: The FP-5000 will respond with an ACK message after each message is received; if the Trip Log is unavailable, the FP-5000 will respond to the last message with a "Buffer Not Available" response.

Note: The FP-5000 does not lock the Trip Log Event buffer. After reading the Trip Log Data buffer, the INCOM Master should re-read the Trip Log Data Summary buffer to ensure that the Trip Log Index has not changed.

Transmit Operation (Trip Log 2) Buffer Description (3 C F) N=060102H Note: This is a continuation of the previous Trip Log Buffer added for Comm Version 2 and

higher only. Messages 2 through 7 are the same in the N=060101H Trip Log Buffer and the N=060102H Trip Log 2 Buffer. This data must be compared to verify data integrity for the combined Trip Log Buffer.

Data is transmitted in Network Byte Order (Big-Endian). This buffer supports the transmission of the trip log stored by the product when a trip occurs. The device has the capability to store information about a maximum of 16 trip conditions. The number of the requested trip log is selected using the (3 F B) command.

Transmit Trend (Data Log) Summary Buffer (3 C F) N=400000H Data is transmitted in Network Byte Order (Big-Endian). The data log is a circular buffer consisting of 1,024 records. The data logger can be configured for a single-pass or a continuous mode of operation. In the single-pass mode, data collection will cease after 1,024 records are logged. The Release Data Log Slave Action (3 D 0, N=03:00:0B) causes the device to release the log and allow the capture of new data. In the continuous mode, records will be overwritten. Each record consists of 2-byte data values for each of the selected 8 parameters. The 1,024 records are partitioned into 128 blocks consisting of 8 records per block to facilitate data transmission. Each block consists of an 8-byte block ID in addition to the 8 data records. The data log also has a header containing the ID of the 8 parameters selected for logging, the selected operating mode, trigger, logging interval, and the settings that define the units for power and demand quantities.

Note: PowerNet supports a minimum logging interval of 1 minute when the data logger operates in continuous mode.

The Data Log Summary identifies the data values stored in the Data Log.

Notes:

The FP-5000 responds with an ACK message after each message it receives. If Message2/Byte2=0 (Waveform request), and if there is a previously requested waveform upload in progress, the FP-5000 responds to the last message with a "Buffer Not Available" response.

Upon accepting a waveform/event buffer request, the FP-5000 sets the "Waveform Data Upload in Progress" bit in the Waveform Summary Buffer Status Flags.
