I use Flexys all the time, but I am trying to do something a little different this time and I’m wondering if it is as easy as it looks… or if it is deceptively difficult.
I normally set up a single IO Server connection to our Allen-Bradley PLC using ABLOGIX, and allow some tags to be read-only and some to be write-only. Now, we have a customer who wants us to talk to a third device using MODBUS via an RS-485 connection. The tricky part is that I need to have the AB PLC read several values that will be supplied by the MODBUS device.
How do I set up an eWON tag so that it is WRITTEN by the MODBUS device, but is read by the ABLOGIX device?
