Counter Under Flow Bit (C5:0/UN): In the Below Ladder Logic, Counter accumulator value under flows when accumulator value reaches -32767 in Allen Bradley PLC Programming. In the below ladder Logic, When we turn ON the I:0/0 ,accumulator value rolls back to 32768 and start counting down ...
This section covers programmable logic controller, PLC programming examples. Every example program includes the description of the problem, the solution as well as PLC code, explanation and run time test cases of the problem. These examples can be simple PLC programs or advanced PLC programs. So,...
Counting down is another operation that is widely used in PLC programming. In some cases you want to know how many counts are remaining before the limit is reached. With the up counter you can use some math to do it. But you can do it easily with a down counter. The Down Counter wor...
Note:The timer and counter in PLC are two different things. Let’s see how these two are different. Difference Between timer and counter in PLC Both have the same function of programming instruction to control and to operate the device. But the main difference in between is- ...
