Digital Communications OverviewThe stand-alone pyrometer communicates only via RS485. When the Interface Module (IM) is used, RS232 and RS485 are both available. Other data formatsIncluding Eathernet, Modbus, Profibus and Fieldbus are available by connecting the stand-alone pyrometer or IM to an AnyBus module.
For the IM, the port selected as Primary provides two-way communications and the other port is continuously streaming the measured parameter values at a burst every 100 ms. Both ports are available simultaneously. In addition, the IM may be configured to provide a data burst to the Primary port upon the shorting of pin 19 to ground.
The RS232 output connector will connect to a computer, PLC or AnyBus Module using a standard monitor extension cable with a DB9 male connector on one end and a DB9 female connector on the other end with straight-through pin connections (pin 1 connects to pin 1, pin A connects to pin A). For computers without a 9-pin I/O connector, a cable with a DB9 male connector on one end and a USB connector on the other end may be used.
Digital Communications are used for Sensor parameter settings may be changed by using the commands shown in the "Williamson Communications Commands, Sensor Parameters" table on the primary communications port.
Continuous Data Stream: All measured parameter values are delivered in a data stream and each parameter value must be parsed off. The data stream is continuously streaming a burst every 100 ms on the secondary communications port. This same data stream is sent continuously in response to an "auto on" command through the primary communications port. Fields are NOT fixed length. All digital data is reported in degrees F. Measured temperature values reported by PRO Series sensors with Firmware lower than 2.0.3874 report only whole integer numbers and must be divided by 1000 to obtain the temperature value. Data Burst: The measured parameter values, or alternately just the filtered temperature value, are sent via the primary communications port in a single transmission burst upon the shorting of Interface Module pin 19. Select ‘Transmit Temp’ or ‘Transmit All” from the "Pin 19 Input" parameter in the "Configure I/O" submenu group. This feature requires an interface module. Willybus: "Willybus" bi-directional communications commands may be used to obtain all measured parameter values as shown in the "Williamson Communication Commands (“Willybus”), Measured Parameters" table. Stand-Alone Multi-Drop Willybus: This feature allows multiple Williamson sensors to communicate digitally using a common four-wire cable. The communication code is identical to the Willybus command shown in the Williamson Communications Commands table, except each command begins with the ASCII code associated with the ID number of a specific sensor (1 through 255).
Anybus: An external module is used for communication via ModBus, ProfiBus Ethernet IP, ProfiNet, DeviceNet or CAN. AnyBus also permits multi-drop operation for pyrometers using firmware revisions that do not support this capability.

Continuous Data StreamThe continuous data stream is sent every 100 ms on the secondary communications port and is started and stopped on the primary communications port by sending the Auto On and Auto Off commands described below. This continuous data stream may be used with HyperTerminal or may be parsed off using a custom-written routine. The data stream must be stopped to communicate using the parameter commands. [Note: The FAST ON and FAST OFF commands may be used to increase the speed of communication when not streaming data if it is necessary to change multiple parameters or to transfer data quickly.]
COMMAND (1) DESCRIPTION
AUTO ON CR This command starts the ‘AUTO ON’ output.AUTO OFF CR This command stops the ‘AUTO ON’ output.
Sample ‘auto on’ output:AUTO=1032.19 1032.48 0 83.8 0 1.000 500 Each string ends with a line feed and carriage return. See the next page for a description of the data string for each sensor type.
Identifier,AUTO= This defines that this packet is an auto-update packet. A user application must handle these identifiers and ignore them.
Unfiltered Temperature (°F),1032.19
Regardless of the sensor setting, the scale for the unfiltered temperature is always in °F. For requirements in Celsius convert the output as follows: °C = [°F – 32] / 1.8.
Filtered Temperature (°F),1032.48
Regardless of the sensor setting, the scale for the filtered temperature is always in °F. For requirements in Celsius convert the output as follows: °C = [°F – 32] / 1.8.
Temperature Status Flag,0 See the next page for a description of the Temperature Status Flag Codes.
Ambient Temperature (°F)83.8
Regardless of the sensor setting, the scale for the ambient temperature is always in °F. For requirements in Celsius convert the output as follows: °C = [°F – 32] / 1.8.
Ambient Temperature Status, 0 01
The ambient temperature is below the specified upper ambient limitThe ambient temperature is above the specified upper ambient limit
Signal Strength / Emissivity1.000
This parameter is a measure of the effective emissivity. When the sensor’s field of view is filled, with no obstructions or background influences, this value represents the emissivity of the measured surface.
Unfiltered Single-Wavelength Temperature
This parameter appears only when the Single-Wavelength Mode is Enabled. Regardless of the sensor setting, the scale for the unfiltered temperature is always in °F. For requirements in Celsius convert the output as follows: °C = [°F – 32] / 1.8.
Filtered Single-Wavelength Temperature
This parameter appears only when the Single-Wavelength Mode is Enabled. Regardless of the sensor setting, the scale for the unfiltered temperature is always in °F. For requirements in Celsius convert the output as follows: °C = [°F – 32] / 1.8.
Signal Dilution500
The signal dilution is a relative measure of infrared energy emitted from the target. A signal dilution factor of 500 : 1 indicates that the sensor has 500 times more infrared signal than is required to make a reading.

Notes: Williamson Communication Commands (“Willybus”), Measured Parameters1. A complete description of measured parameters is provided in the applicable operating manual. Different sensor types report different
measured parameters according to the chart below. Staring sensors are single-wavelength sensors that have no moving parts and continuously stare at the measured target, including all Gold Series sensors. Auto Null sensors are single-wavelength sensors that include a spinning chopper wheel.
2. Temperature Values are reported in degrees F regardless of the Units parameter setting in the sensor setup menu.3. SWL (Single Wavelength) Energy, Unfiltered Temperature, and Filtered Temperature parameters are available in Dual- and Multi-
wavelength sensors using software code 2.0.5837 (July, 2009 release) and later, with IM firmware 2.0.2914 and later, and only when the Single-Wavelength operating mode is Enabled in the Configure ESP Submenu. When not Enabled or when using an earlier sensor software version, the command is considered invalid and the returned response is blank as described below (see note 9).
4. All commands consist of 2 characters, and must be terminated with a CR-LF. (Carriage Return, Line Feed) Example: FT<CR-LF>. Commands are not case sensitive. For multi-drop sensors, each command must be preceeded by the sensor ID number written in ASCII format. For example, %FT will return the filtered temperature reading for sensor number 37. ASCII codes for numbers 1 to 127 are shown below.
5. All responses are terminated with LF-CR. (Note that the sequence is reversed from the command.) Example: 1234.56<LF-CR>.6. All responses are fixed length, according to the Format column.7. Commands may be combined on a single line, using a comma as a separator. Example: FT,SS,AT<CR-LF>. Response will also use comma
separators, and will occur in the same order as the command. Example: 1234.56,0.872,84.5<LF-CR>.8. Incorrect commands result in blank responses. For example: FT,XX,AT results in 1234.56,,84.5<LF-CR>.9. The default baud rate is 38400. When using the Interface Module, the baud rate may be set to 9600, 19200 or 38400. Similarly, a 2-wire
RS485 format may be selected.

Modbus, Profibus, Fieldbus and Hart Communications
Any industry standard digital communications protocol may be used to communicate with a Williamson pyrometer by using the available AnyBus module. AnyBus modules are specified with a different part number for each protocol.
To use the AnyBus communications module, enter the “Configure Network”.submenu group to make all the required configurations.1. Baud Rate – Must be set to 384002. Protocol – Must be set to Fieldbus3. Address – If only 1 sensor is attached to the Anybus Communicator, the address is optional. It can be set to Disabled. By doing so, the sensor will ignore the address byte sent by the Ethernet host. (Note that the address byte must still be used. Its value will not make any difference to the sensor.) If an address is selected, the sensor will ignore any other addresses received from the host. If more than 1 sensor is attached, each sensor must have a unique address in the range of 1-255.4. Sensor RS485 – Select either Full Duplex or Half Duplex, depending whether a single sensor or multiple sensors (multidrop) is used:a. For single sensor, 4 wires, select Full Duplex. See Figure 7.b. For multiple sensors, 4 wires , select Half Duplex. See Figure 8.c. For single or multiple sensors, 2 wires, select Half Duplex. See Figure 9.

Half-Duplex ModeThe Gold and PRO Series Williamson pyrometers are designed to operate in a Full-Duplex (four-wire) communications format; however, it is possible to communicate digitally using Half-Duplex (two wires). At Williamson we prefer to refer to the two communication modes by Full-Duplex and Half-Duplex to avoid confusion because the half-duplex mode actually requires four wires (two for the communications and two for power). The two-wire configuration is not as robust as is the four-wire configuration when using the stand-alone transmitter, so please be aware of the limitations described below.
Full-Duplex Digital Configuration with Interface ModuleIn this mode, both RS232 and RS485 communication is available. One port is set to bi-directional communication and the other is streaming measured parameter data.
Half-Duplex Digital Configuration with the Interface ModuleIn this mode, both RS232 and RS485 communication is available from the interface module. One port is set to bi-directional communication and the other is streaming measured parameter data. The communication between the Williamson pyrometer and Interface Module can not be set to two-wire mode.
Stand-Alone Full-Duplex ConfigurationIn this mode, RS485 must be used to communicate with the pyrometer using bi-directional communication commands or initializing a stream of data using the “auto on” command. The “Willybus” commands that provide measured parameter data via bi-directional commands will not function in the stand-alone configuration. In this mode, the measured parameters are available only by parsing the streaming data.
Stand-Alone Half-Duplex ConfigurationIn this mode, RS485 must be used to communicate with the pyrometer using bi-directional communication commands or initializing a stream of data using the “auto on” command. The “Willybus” commands that provide measured parameter data via bi-directional commands will not function in the stand-alone configuration. In this mode, the measured parameters are available only by parsing the streaming data. When using the half-duplex communication mode to read the streaming data, any digital command sent to the sensor must be received during the “dwell time” between data bursts.
Half-Duplex Mode Set UpEvery Gold or PRO Series pyrometer may be configured to operate in half-duplex mode by shorting the Receive + and Transmit + wires together and shorting the Receive – and Transmit – wires together and by entering the hidden factory options submenu and setting the “Comm Type” parameter to “4Wire” (two communication wires and two power wires).
Secret KeystrokeTo enter the hidden “factory options” set up menu using the Interface Module, press the Menu button to enter set up mode, then press and hold the aim light button. While still holding the aim light button, press and release the Menu button. Release both buttons and press the up arrow. If performed properly, then “Factory Options” will appear. If not, then repeat. To enter the hidden “factory options” set up menu using the stand-alone
9
pyrometer, press and hold the middle button for ten seconds before entering the set up mode by pressing the two outside buttons. Press the up arrow, and “factory options” should appear. If not, then exit the set up mode and repeat.
Note Pertaining to the Measured Parameter Data Stream When Operating in the Stand-Alone Half-Duplex ModeThe “auto on” command is not recognized by the stand-alone pyrometer in two-wire mode. The four-wire communication mode must be used to initialize the stream of data. Once the data steam has been initialized (using a laptop computer, for example), then the sensor can be set to operate in the half-duplex mode and the jumpers may be used to convert from two-wires to four-wires. If power is lost, the sensor boots up in four-wire mode and the process must be repeated.

Notes: Williamson Communications Commands, Sensor Parameters1. This command-based communications set operates in the stand-alone mode or with an Interface Module. Some parameters are found only in
newer sensors. Where applicable, notes have been provided to identify these parameters.2. A complete description of sensor parameters is provided in the applicable operating manual. Different sensor types use different parameters
according to the chart below. Staring sensors are single-wavelength sensors that have no moving parts and continuously stare at the measured target, including all Gold Series sensors. Auto Null sensors are single-wavelength sensors that include a spinning chopper wheel.
3. Temperature Values must be set and reported in degrees F regardless of the Units parameter setting in the sensor setup menu.4. All commands consist of the phrase, “Set COMMAND=Value”, where COMMAND is the Serial Command shown in the table below, and
Value is the value associated with the parameter setting. All commands must be terminated with a CR-LF. (Carriage Return, Line Feed) Example: Set ESPTABLE=2<CR-LF>. Commands are not case sensitive.
5. Sensor parameter settings may be polled using a similar command, except using the word Get. For example, : Get ESPTABLE<CR-LF> returns the parameter value.
6. Menu Name: The description of the parameter function. “Pass-Through” indicates parameters inaccessible through the Interface Module. Enter Pass-Through mode using “Pass<CR-LF>” and exit Pass-Through mode using “Cnt’l A”. Pass-Through disables the Interface Module.
7. Serial Command: The command that must be given to change the parameter setting.8. Values: A value associated with each command.
a. For numeric values, the range of valid values is given. For example, for 1-240, any whole number between 1 and 240 may be entered.b. For alpha numeric values, the line number within the table is the value entered, with the first row being a value of 0 and the second
row being a value of 1, and so on. For example, when setting the Output1 Parameter, a value of 3 sets the parameter to “Signal Strength” because this parameter value is shown on the fourth line. The parameter number corresponds to the line number even when parameters are found that are not applicable to the model used.
c. When “bottom-top” is specified, then this means that the valid range of parameter values is any value within the specified range of the sensor. For example, if the sensor has a specified range of 700 to 2100 F, then any temperature value within this range may be entered. Please note that the 20 ma temperature value must be higher than the 0/4 ma temperature value.
d. “Chars” refers to the number of alpha-numeric characters that may be entered. “9 Chars” means that the value may be set to any alpha-numeric value of 9-characters or less.
e. 2.0.XXXX refers to the read-only revision numbers for the hardware firmware revision.f. (1), (2) or (3) refers to a parameter that is only found in a particular type of sensor. (1) is Dual- and Multi-Wavelength. (2) is Auto
Null), (3) is Staring. Note: When the term “Multi” is used, it means both Dual- and Multi-Wavelength sensors.9. Default: This is the default value for each parameter. “Ambient” refers to the Factory Submenu parameter defining the Ambient
Temperature Limit for each model. 10. Divisor: The parameter value is divided by this value to report the units. For example, an Average Time Value of 21 shows a Divisor of 10,
so the parameter value is actually 2.1 seconds (21 divided by 10).11. Sensor/Display indicates if the parameter value is stored in the S = Sensor or in the D = Interface Module (Display).12. Dual/Multi, Auto Null, Staring, Pilot Monitor, Quench: A check mark indicates that the parameter is associated with this sensor type. 13. Sensor parameter settings are loaded and applied in 300 ms or less for the stand-alone sensor and 700 ms or less through the Interface Module.14. The default baud rate is 38400. When using the Interface Module, the baud rate may be set to 9600, 19200 or 38400 in the factory options
submenu. Similarly, a 2-wire RS485 format may be selected in the factory submenu.11
