Appendix A.5. Configuring a PLC to read and write data to and from FieldServer
This example makes use of the Data Table Read/Write method for passing data between the FieldServer and an
Allen Bradley PLC. The example shows configuration of a ControlLogix PLC, but all Rockwell PLC’s that support
Ethernet IP communications and Data Table Read/Write operations in Message blocks should be able to
communicate this way. The Map Descriptors create an explicit connection to the Server and then transfer data in
the data table format. The EIP_Tag_Name field contains the tag name polled from the client. DATA_TABLE_READ
and DATA_TABLE_WRITE are the only legal values for EIP_SERVICE.
Note that this is by far the preferred method for communicating with Allen Bradley PLC’s due to its ease of
configuration, quantity of data that can be transferred and speed of transfer.
