Without Display, S7-1200 is the first SIMATIC PLC that there is no RUN / STOP key (except the LOGO! without Display). I see, here in the forum, many comparisons with S7-200 / S7-300 but until now no one about the RUN / STOP key. What they think about it?

I see, here in the forum, many comparisons with S7-200 / S7-300 but until now no one about the RUN / STOP key. What they think about it? Hello Pegaia, Oops I didn’t notice it until you say. (Unfortunately I haven’t got 1200 yet in my hand). Well I think there should be a run/stop switch. I mean there are advantages and disadvantages of having a key switch. The main advantage is if you done some thin wrong you can make PLC stop immediately with out cutting power or stop from the software. And main disadvantage is unauthorized activation of switch (if the switch is a key switch like good old s7 300 it won’t be a problem). Also as Tomy Master mentioned the TREM mode is also missing. So my personal feeling is it is better to have a run/stop switch than no run/stop switch. (This is my idea only may be siemens having better ideas with out run/stop switch) Best regards.
