Hi everybody,
I want to pass data between the PLC5-processor (5/20) and the Basic Module 1771-DB series A using synchronous Block Transfer. I have an attachment file include with the rungs and the basic-program for the Basic-module. The problem is when the basic-program execute Call 6 (row 50) nothings happen, call 6 means that this routine receive data from the plc and the active bit from the Input Image Table
(I:013/1) must be '1'. But I:013/1 is not '1' so the rung for the BTW is not true and nothing happend. When I toggle bit I:013/1, the rung is true and data is being received.
The same is for the BTR. Who can help me what the problem is?
Greetings,
