10. Troubleshooting
L
Please check the following points if problems arise when setting
up a connection:
1.
Have you paid attention to the LED messages?
2.
Check wiring and connections.
3.
Is the connection between the controller and terminal device
correct?
4.
Have all screw terminals been correctly tightened?
5.
Has the correct baud rate been set?
6.
Is the transmission path too long for the selected baud rate?
7.
Have all addresses been set correctly?
8.
Has the system been restarted since last changing the bus
addresses? The devices are initialised after each restart.
9.
Has the bus been correctly set (last module) and the jumper
set correctly?
10. Heed the guidelines for individual assemblies in the software.
