Two module I/O servers. one serial port

[MarkCG]

is this possible? it's logical that you'd wan't to put multiple device on one serial network, in order to not have add extra ports to you controlller. I can't seem to find the answer. I ould think that the API handles sharing of the port behind the scenes, but who knows. Can I save myself some work and use the I/O server, or am I going to have to do this the old-fashioned way and use the modbus library?

As long as you are using a 485 port you should be able to communicate with multiple devices using Modbus over Serial.  It does look a bit strange because you need to have a different I/O server for each slave device but you can set them to all use the same serial port.
