Good one to write on the cabinet door. Nobody ever remembers the 256 family exists.
Sounds like the tag types. In WinCC that error usually means the connection is there but the addresses behind it don't match what the controller has. ...
CVHLimit to 60% and pulled the LIM. Then a rung: no steam pressure for 30 seconds puts the loop in Manual with CV at 20%, steam back for 60 seconds pu...
took the ONS out. ACC counts up to 3000ms, DN goes on, pusher fires. The one-shot was only ever letting the rung be true for a single scan, so the tim...
SUB, ABS, LES 0.001 in the ladder version and the ABS line in ST. Match comes on for 0.1 + 0.2 now, on Emulate and on the 1214C. Neither 0.1 nor 0.2 ...
RTD is fine, tracks the local gauge. Auto the whole time, nobody's on site to change it. CVHLimit is 100%, CVLLimit 0%, and yes, there's a LIM 0 to 60...
Removed the extra pin, compile clean. Wrote the alarm as a separate network in FC_Main using the sensor input directly and the FB's Running output, do...
0.30000001 for Sum, 0.3 for Setpoint. Oh. So they aren't equal, not quite. I think I see it. Why doesn't 0.1 plus 0.2 make 0.3? And no status bit, the...
It was in an example I copied out of a training PDF, for catching the part arriving. I thought it'd make the timer start once when the eye goes on, bu...
Done. Tilted the eye down a bit and put the 20ms TON in front of C5:0 with the DN bit. Two shifts now and the count's within 1 or 2 of the tally each ...
> Why doesn't it fault on Emulate then? Because nobody typed 20 into your emulated HMI. The controller checks the index at runtime on whatever Idx...
Error is: "The interface of the called block 'FB_Labeller' does not match the call in 'FC_Main', network 3." Close to that. I added a new input pin o...
