Hi,
It's the first time that I have to build logic from scratch in safety Functions.
When you have a standaard PNOZ, you have 2 channel-inputs.
The question my boss asked was if a 1-channel Emergency-Stop circuit can be combined with a 2-channel Emergency-Stop circuit in the Safety logic of a PLC.
I don't know much about safety, but isn't this just the same as other logic ?, except that it Runs in a Fail-Safe area, an area that keeps running when the cpu stops because of hardware or software faults...
My boss thinks that an emergencystop input has to be 2-channel or single-channeled, combinning not possible ?
Someone who can tell me the comparision with a Multipnoz ?
Thanks,
Regards,
Combo
