The Modbus server makes data collected by Profile available to other Modbus clients.
Before setting up the Modbus server, please ensure that the Modbus server’s Modbus map has been setup for each configuration.

|Protocol||Modbus TCP or Modbus RTU.|
|IP Address (TCP only)||The TCP/IP address of the Modbus server should listen on.|

|Validity||This is how long in seconds that data will be regarded as fresh. Once the validity period has been passed the data will be marked as stale and the Modbus server will throw an “04″ exception error.|
|Block Size||This is many Modbus addresses will be reserved for each RTU. It defaults to 100.|
This window shows all the RTUs on the system and the blocks that they are using. The blocks cannot be adjusted or reordered.
The Modbus map extrapolates the configuration’s Modbus map for each RTU. Click here for more information.
