Most engineers love FBD because it is graphically a very common way to describe a system. It is a great way to implement everything from logic to timers, PID controllers, and even a SCADA system in your solution, etc. Function Block Diagram is easy to learn and provides a lot of possibilities.Īs one of the official PLC programming languages described in IEC 61131-3, FBD is fundamental for all PLC programmers. It is a simple and graphical way to program any functions together in a PLC program.

How else might I initiate and stop the light sequence? Thank you for your help. I tried removing the latch in the start bit rung but then needed to hold the push button for the program to work. The program starts immediately upon the RUN without the push button input and the counter doesn't stop the when O is reached. There are two clues that I believe are significant but I have been unable to figure out a solution. It does have the LOAD NOT bit addressed to the counter to turn off the start bit. My final rung(excluding the end) uses the final timer output to cycle back to the first light in sequence. I have placed the sequence stop LOAD NOT bit in the start rung and in series with the timers on each rung. The timer correctly changes the LOAD NOT bit to turn off the first light and turns on the next rung. The start work bit turns on the first light and initiate the first timer.
The counter counts down correctly to 0 but doesn't change the status of the stops. I programmed a start switch with a hold-over latch to begin the sequence and have programmed the CNT output to energize a LOAD NOT stop bit in each run. I am writing a program to use a sequence of 4 flashing lights to simulate energizing the fields in a stepper motor and using a counter to stop the sequence after 9 cycles.
