Hi all!
I have one question. How to indicate ringing (incoming call) in program in s7-300.
I am using CP 340 and siemens mc35i connected via rs-232c
I have tried to use "v24_stat" block with correct "ladd" (first adress as in hw configuration) but dont get "RI_IN" output active.
Other outputs are correct. (when i disconnect modem outputs are changed).
Does anyone have an idea or advice?
Correct (working) shematic of cable??
Please help.
