Page 13: Map Descriptor Examples
6.3.4 Slave_Id The following Map Descriptor is used to respond to the Report Slave_Id request. The FieldServer's Slave_Id is 11 and the run status depends upon the data validity at the specified offset in the specified Data Array - if the data is valid, the status will be 255 (running) otherwise the status will be 0 (off). -
Page 14: Appendix A. Useful Features - Modbus Rtu
The following example shows how scaling can be achieved on the Server side of the configuration. Note that scaling can also be done on the Client side to scale down a value that was scaled up by a Modbus vendor. Further information regarding scaling can be found in the FieldServer Configuration manual. -
Page 15: Appendix A.1.2. Transferring 32 Bit Values With Two Registers
If a Modbus Server sends two consecutive registers to the FieldServer representing either a floating point value or a 32 bit integer value, the FieldServer can combine and decode these registers back into their original format. To do this, the user must read the registers into an integer data array, and then use the Moves function to move the data to a floating point or 32 bit integer data array. -
Page 16: Appendix A.2. Node_Offline_Response
Server Node is offline. Zero_Data - The FieldServer will respond, but with the data values set to zero. If the user normally expects non-zero values, this option will signal the offline condition without disrupting communications. -

Page 18: Appendix C. Troubleshooting
Appendix C.1. Server Configuration of System Station Address When using the FieldServer as a Modbus Server, the FieldServer System Station address must be configured to be different from any of the configured Modbus Server Node_ID’s. Configuring these to be the same invokes proprietary system information to be transmitted, and should therefore be avoided. -

Appendix D.1. Connection to York Modbus Microgateway If connecting the FieldServer to a York Modbus Microgateway, the Node_ID of the Microgateway is defined by the address DIP switches. If switch 4 is set to ‘On’ and the other switches are set to ‘off’ then Node_ID of the Microgateway is ‘247’, the parity is ‘Even’, and the stop bits are 1. - Page 20 FS-8700-01 Modbus RTU/ASCIIFS-8700-01_Modbus_RTU Driver Manual Device is D11, select 5-digit address, add the FieldServer virtual Node ID to station address Set up poll record SAVE the configuration.
