Hi All,
I have modbus comms working to many devices using ML1400's and the NC01 adapter.
I have one flowmeter in particular from Toshiba that refuses to talk to my 1400, but talks to Modscan on my laptop just fine.
Of course, my port settings are set up OK on both PLC and Logix end. I'm reading an integer value from register 40001 just fine in Modscan, but when hooked up to PLC, reading nothing but time outs.
I've swapped A and B and changed all sorts of things in my MSG block and port settings to no avail.
I've never had this much trouble communicating to a device before. Toshiba tech recommends me buying a RedLion converter box of some type to help get the signal into the ML1400... I am not sure of that...
Anyone have any ideas?
Thanks!
