Ok this is my first post so if im off etiquette let me know....
I'm trying to setup communication between a
Telemecanique TWDLCAE40DRF plc
using a rs485 3 terminal port
with this port setup as a slave
talking modbus.
Other Modbus device
Delta Controls Bacnet router (DSM-RTR-MOD30),
Im using Twidosuite as my programming software. The port is set to slave. In <b>describe</b>, I added a generic modbus device and linked that device to my 485 port.
Now my transmission settings (baud rate, etc..) are the same as the other tech's settings in the bacnet controller. His controller is set to master for his port. His port is showing lights on the TX blinking when sending requests but his RX light is solid. I disconnect the Rx wire and his light stays on. Don't know if this is a problem.
2 wire cable connecting both are connected positive to positive and (-) to (-).
We cant get them to talk to each other. He's getting invalid signals on his end in his network traffic statistics.
Has anyone succesfully configured the two systems to talk?
or
Should I get my hands on a serial to ethernet converter and see if I can get my ethernet port to talk to his 485?
Any help would be appreciated
Thanks
Jeremi
