FS-8700-24 ControlNet Driver Manual Page 3 of 12 1. ControlNet Description The ControlNet driver allows the FieldServer to transfer data to and from devices using ControlNet protocol. The SST 5136-CN-ISA Communications Adapter card is included with the FieldServer. The FieldServer can communicate using un-scheduled transfers with PCCC messages embedded in the ControlNet messages. When the FieldServer originates PCCC messages to communicate with PLC5 controllers, it uses connected

This is the ability of a Read Map Descriptor to automatically create a temporary write Map Descriptor to update the value of an external R/W (Read or Write) memory location. Since the ControlNet card contains separate Read-Only (Output) and Write-Only (Input) Buffers, write-throughs are not supported on ControlNet messaging, but
