The article presents the method of terminating the TF-Bus line. Termination will allow to eliminate possible communication interferences.
The diagrams shows the termination on the DIN rail modules as well as flush-mounted modules and touch panels.
TF-Bus termination diagram:
In the case of DIN rail modules, termination is performed only by placing a jumper (2.54mm) in accordance with the diagram below (the resistor is on the board):
For flush-mounted modules, termination is performed by using a 120Ω resistor and connecting it between A and B communication channels:
