hi, It depends on what you want to do with this input. In S7-1200 system-manual you find all supported applications regarding the HSC on the S7-1200. SIMATIC S7 S7-1200 Programmable controller just to use ":P" is only a direct access to the perphery. You don´t know what happens between two accesses. I guess you rather need a process-alarm. When the input gets high, a process-alarm-OB will be called and you can react to this input inside this OB. hope this helps, regards, |
