Sending data via send/receive function block from AC800F to third party PLCs
Has anyone tried to use send/receive function block to send data to third party PLCs?
If third party PLCs requires the header (as shown in the picture) to receive the data, is it possible to hard code that header and AC800F and send it together with the data?

If you want to connect a Freelance CPU to a PLC via Send/Receive, the PLC has to understand the header Freelance uses. Freelance can not change the header, but PLCs usually can, because they can access their physical memory directly byte or bit wise.
Attached is a rather technical description of the structure used for send/receive.
