No. Did you use the central communication block? Did you enable the transfer FBs in CFC? ------------------ I made a small program, and it runs I used a marker instead of a input module. OB1 copies the MB0 to the FM and the FM to MB100. When I set M0.7 the signal is shown in the FM. The EXM438 is just in HW Config because I have it in my rack, it has no function here. The FB 1in the FM is interpeting the first byte as interger, just to monitor what's going on. FB 2 shows the binary (bool) signal. FB 3 is the test in the other direction, from FM to S7. The attachment holds the program and two screenshots Picture 0.jpg shows the transfer with logical 0, 1.jpg with logical 1. In 1.jpg I set the input off FB 3 manually to logical 1.
