1756-EN2T Digital output relays

1756-EN2T In the choice of programming language, whether to program with ladder diagram or statement table or use function chart, it mainly depends on the following points:

(2) Experienced personnel can use statement table direct programming, just like using assembly language.

(3) In the case of clear single-sequence, selective-sequence or concurrent-sequence control tasks, it is preferable to program the program using a function diagram.

1756-EN2T Safety is of the first importance. Even if the programmable controller malfunctions when the power supply from the outside is abnormal, the whole system can work in a safe state. the following safety circuits should be set up outside the programmable controller: emergency

The safety of the 1756-EN2T is of the first importance. Even in the event of an abnormality in the external power supply and a malfunction of the programmable controller, the entire system can work in a safe state, and the following safety circuits should be set up outside of the programmable controller: emergency stop circuits, protection circuits, interlocking circuits for opposite operations such as positive reversal, interlocking circuits to prevent damage to the upper limit/lower limit line of the positioner, and so on, to prevent malfunctions caused by misoperation. This prevents malfunctions caused by misoperation.
