The Series 90 TCP/IP Communications enabler supports a compound message format for unsolicited data that allows the PLC to send multiple registers in a single unsolicited message.
The enabler uses defined Transmission Areas to determine if a message is a simple or compound unsolicited message. You can configure up to eight of these areas by adding entries to the global parameters file that define the transmission area number (1-8) and starting address in the PLC.
The following is an entry to use %R500 as a transmission area:
When using Compound Messages:
You will need to define a point for each sub-packet with the correct domain, offset and length.
GE Fanuc recommends that you not configure points that conflict with addresses in the unsolicited transmission areas.
