Hey guys,
I've got a system I'm coded up, it is using three SCADAPack 357 controllers. Out in the field, they'll communicate via TeleDesign TS4000 radios with Modbus RTU (RS232) (one master, two slaves). The problem is, I won't have access to the radios on my bench, but I want to be able to do some testing of comms before I integrate onsite.
If it was Modbus TCP it would be easy, since it's just an ethernet connection. But with Modbus RTU via RS232 it's obviously a serial connection, not ethernet.
What I'm wondering is whether or not there's a straightforward way to test the serial connection between all three PLCs without having the actual radios at my disposal. Does anyone have any ideas on how you might go about this?
Thanks!
