I'm sure this has been asked before but I'm looking for a modular plug and play option.
We have:
HMI (Delta DOP-B03S211 has 2 RS485 ports or 1 RS232)
Modem (Advantech Smartstart)
Slave 1 (Proprietary board).
HMI and Slave 1 have software written for the 2 to be married together. Minor code changes is an option. Changing cables and rewiring is an option though. Adding a PLC or another device somewhere on the network to handle the com traffic is an option as well. The HMI and modem would be reading/writing the same tags on the slave.
I would be looking for a solution to plug into the existing network.
The ideal situation would be this: HMI--Slave 1--Modem. That way both the HMI and modem can write into slave 1 at the same time not having to do any major code writing for the HMI.
Please advise. Thanks.
