plc program
How to use the INT instruction in Mitsubishi PLC, why INT 100.00=99? INT is a floating point number to integer, 100.000=100 But your plc program is not equal to 100, it must be used in other places, so the value of D40 has changed. such as:
NEW Digital Keypad Operation Panel Replace Delta VFD-M LC-M02E 2 Month warranty
Timer and CounterThe timer in the PLC counts the time, and the counter counts the events.The timer does count only the time, and the counter has a certain period of time because the PLC has a scan period, and the timing can be implemented with the timer or the corresponding logic.Similarities and differences between timers … Continue reading What is timer and counter in PLC?
Time control programming exampleThe timer of the Mitsubishi plc FX series is a power-on delay timer. Its working principle is that after the timer coil is energized, the delay starts, the time is up, the contact action; when the timer coil is powered off, the timer The contact is instantly reset. However, in practical applications, … Continue reading Time control programming example implemented by Mitsubishi PLC with timer and counter

Write a general mode parallel link communication programTwo FX2N series PLCs exchange data through a 1:1 parallel link communication network, designing oneGeneral mode communication program. The communication operation requirements are as follows.(1) The ON/OFF status of the master station XOOO to X007 is output to the slave station through M800 to M807.YOOO—Y007.(2) When the calculation … Continue reading How to write a general mode parallel link communication program?
N:N network parametersSetting requirements: Set the PIC as the master station, set the number of slave stations to 2, and use the mode 1 brush.New, the number of communication retries is set to 3, and the communication timeout is set to 40ms.Solution: Set according to the setting requirements, and get the program ladder diagram. M8038After … Continue reading How to program the master station setting program for N:N network parameters?
PLC program execution order(1) The ladder diagram should be programmed with the left bus as the starting point and the right bus as the end point, from left to right, written line by line.The beginning of each line is the starting condition, consisting of normally open, normally closed contacts or a combination thereof. The rightmost … Continue reading What is the execution order of the PLC program?
