1.1 Configuration with Modbus RTU Modbus is a client/server protocol for communication between network linked devices. Modbus devices communicate using a master-slave technique in which a single device (the master) can send messages. All other devices in the network (slaves) respond by returning the data required to the master or executing the action indicated in the message received. A slave is defined as a device connected to a network that processes information and sends the results to a master using the Modbus protocol. The master can send messages to individual slaves or to the entire network (broadcast) whilst slaves can only reply to messages received individually from the master. The Modbus standard used by Eliwell uses RTU coding for data transmission.
1.1.1 Data format (RTU) The data coding model used defines the structure of messages sent to the network and the way in which the information is decoded. The type of coding selected is generally based on specific parameters (baud rate, parity, etc)*** and some devices only support specific code models. However, the same model must be used for all devices connected to a Modbus network. The protocol uses the RTU binary method with the following bytes: 8 bits for data, even parity bit (not configurable), 1 stop bit. *** configurable via parameters CF64, CF65 – see table at beginning of this section. N.B.: transmission speed must be set at 9600 baud. Every aspect of the device can be configured via parameters. They can be modified by means of:
Instrument keyboard Copy Card by sending data via the Modbus protocol straight to individual instruments, or via broadcast, using the address 0
(broadcast).

1.1.2 Modbus commands available and data areas The commands implemented are:
Length restrictions
maximum length in bytes of messages sent to device 30 BYTE maximum length in bytes of messages received by device 30 BYTE
ATTENTION! It is necessary to require the reading of 2 registers (WORD) to obtaining 1 register on answer. The request of reading only one register cause the reading of the highest byte. ATTENTION! In order to write values to WORD is necessary to send the request of writing with 2 registers, it will obtain an answer of dimension 2.
Modbus command Description of command 3
Read 16 consecutive registers on Client side Read 1 single register for parameters.

To identify the index of the first record present, read variable PntStorAll at the address h024F To identify the number of records present, read variable NumStorAll at the address h0250 For example: if the address of PntStorAll=0x2C1 and the address of NumStorAll=0x2C2: TX: 01, 03, 82, C1, 00, 02, BD, 8F. RX: 01, 03, 04, 00, 27, 00, 27, 0A, 22. Address 0x82C1 => data: 0x0027 = index of first record (the most recent); Address 0x82C2 => data: 0x0027 = number of records present (39); To calculate the address of the most recent record: Address EU00 = 50432 + (N-1)x7 = 50432 + 38x7 = 50698 (0xC60A)
EWCM4000 Modbus 6/22
Read EU00 TX: 01, 03, C6, 0A, 00, 07, 18, 82. RX: 01, 03, 0E, 00, 02, 00, D6, 00, EF, 00, BE, 00, 00, 00, 04, 00, 3C, C9, F3. Address 0xC60A => data: 0x0002 = Byte 0 of alarm log record; Address 0xC60B => data: 0x00D6 = Byte 1 of alarm log record; Address 0xC60C => data: 0x00EF = Byte 2 of alarm log record; Address 0xC60D => data: 0x00BE = Byte 3 of alarm log record; Address 0xC60E => data: 0x0000 = Byte 4 of alarm log record; Address 0xC60F => data: 0x0004 = Byte 5 of alarm log record; Address 0xC610 => data: 0x003C = Byte 6 of alarm log record; Alarm record free flag = b 0 = 0 Alarm state = b 1 = 1 Automatic reset alarm = b 0 = 0 Not used = b 00000 = 0 Start of alarm minute = b 010110 = 22 End of alarm minute = b 111111 = 63 (undefined) Start of alarm hour = b 01110 = 14 End of alarm hour = b 11111 = 31 (undefined) Start of alarm day = b 00010 = 2 End of alarm day = b 00000 = 0 (undefined) Start of alarm month = b 0100 = 4 End of alarm month = b 0000 = 0 (undefined) Alarm code = b 00111100 = 60 The result shows that on EU00 there is an Er60 that started on 02/04 at 14.22 and it is still active. To read EU01, the address is determined as follows: Address EU01 = Address EU00 - 7 = 50698 - 7 = 50691 To read EU02, continue by subtracting 7 from the address EU01 and so on. N.B.: The minimum limit is the address 50432 after which, any other alarms still to be read will start again from 51125 (the buffer is circular and after the 99th record, the oldest ones are rewritten). Details to read/set the time To write the time, address the DataWrite structure to h0064 Write the seconds byte last! Example: configuring the time 11:33 on 28/03/2007

1.2 Configuration of device address The Device Number in a ModBus message is defined by the parameter CF63 – see table at beginning of this section. The address 0 is used for broadcast messages that all slaves recognize. Slaves do not reply to broadcast messages.
1.3 Visibility and Value of Parameters There are 2 hardware models (EWCM4120 e EWCM4180) with varying numbers Inputs/Outputs. Depending on the model, some configuration parameters may not (usually) be visible and/or be of no significance given that the associated resource is not present. Particularly we will have that the following parameters will be present on EWCM4180 model and not on EWCM4120 model: CF27, CF30, CF33, CF35, CF36, CF38, CF39, CF41, CF42, CF44, CF50 When not indicated otherwise, the parameter is always visible and modifiable, unless customised settings have been configured via serial. N.B.: If folder visibility is modified, the new setting will apply to all parameters in the folder.
1.4 Parameters/visibility table and Client table The tables below list all information required to read, write and decode all accessible resources in the device. There are two tables:
- the parameters table contains all device configuration parameters stored in the instrument's non-volatile memory and the visibility.
- the client table includes all I/O and alarm state resources available in the instrument's volatile memory. Description of columns: This indicates the label of the folder containing the parameter in question This indicates the label used to display the parameters in the instrument's menu. The whole part represents the address of the MODBUS register containing the value of the resource to be read or written to the instrument. The value after the point indicates the position of the most significant data bit in the register; if not indicated it is taken to be zero. This information is always provided when the register contains more than one information item, and it is necessary to distinguish which bits actually represent the data (the working size of the data indicated in the DATA SIZE colum is also taken into consideration). Given that the modbus registers are the size of one WORD (16 bit), the index number after the point can vary from 0 (least significant bit –LSb–) to 15 (most significant bit –MSb–).

Important: when the register contains more than one data item, during the write operation proceed as follows:
read current register value modify the bits that represent the resource concerned write the register
Same as above. In this case, the parameter visibility value is in the MODBUS register address. By default, all parameters have:
Data size 2 bit Range 0…3 **Visibilità 3 U.M. num
** Value Meaning
Value 3 = parameter or folder always visible Value 2 = manufacturer level; these parameters can only be seen by entering the manufacturer's password
(see parameter UI18) (all parameters specified as always visible, parameters that are visible at the installation level, and manufacturer level parameters will be visible).
Value 1 = installation level; these parameters can only be viewed by entering the installation password (see parameter UI17) (all parameters specified as always visible and parameters that are visible at the installation level will be visible)
Value 0 = parameter or folder NOT visible
1. Parameters and/or folders with visibility level <>3 (i.e. password protected) will only be visible if the correct password is entered (installation or manufacturer) following the procedure outlined below:
2. Parameters and/or folders with visibility level =3 are always visible and no password is required; in this case, the procedure below is not required.
Examples (in binary form the least significant bit is the first on the right): Default visibility:

R Read-only resource. W Write-only resource. RW Read / write resource.
It is the description of the parameters meaning in the LABEL column. Indicates the size of the data in bits.
WORD = 16 bits Byte = 8 bits “n” bit = 0...15 bits depending on value of “n”
When the field indicates “Y”, the value read by the register must be converted, because the value represents a number with a sign. In the other cases the value is always positive or null. To carry out conversion, proceed as follows:
if the value in the register is between 0 and 32,767, the result is the value itself (zero and positive values). if the value in the register is between 32,768 and 65,535, the result is the value of the register - 65,536 (negative
values).
EWCM4000 Modbus 9/22
Describes the interval of values that can be assigned to the parameter. It can be correlated with other parameters in the instrument (indicated with the parameter label).
RANGE
DEFAULT
EXP
U.M.
Indicates the factory setting for the standard model of the instrument. If = -1 the value read from the register is divided by 10 (value/10) to convert it to the values given in the RANGE and DEFAULT column and the unit of measure specified in the U.M. column. Example: parameter CF04 = 50.0. Column EXP = -1:
The value read by the device/ParamManager is 50.0. The value read from the register is 500 --> 500/10 = 50.0.
Measurement unit for values converted according to the rules indicated in the CPL and EXP columns.
