Looking for a multi-master Modbus RS232 multiplexer. An HMI and a PLC or two PLC masters talking through a modem to multiple Modbus RTUs.
We have tried Calta but had difficulty with it when working with Verizon and ATT phone lines. The individual lines work fine without the mux. The Calta unit works fine with dedicated District owned lines.
Thanks,
Jerry
