M8013 is a 1 second clock oscillation pulse, Y1 is the alarm output (flashing alarm).
Mitsubishi plc k4m100 K1 represents four consecutive addresses, and K4 represents 4 x 4 consecutive addresses, that is, 16. Similarly, K2 is 8 consecutive addresses; K3 is 12 consecutive addresses. M100 is an address, K4 represents 16 bits from M100 to M115, not M100 represents 16 bits.
The Mitsubishi PLC constant H represents a hexadecimal number and is mainly used to indicate the operational value of the application function instruction. [extension] K is a symbol indicating a decimal integer. It is mainly used to specify the set value of the timer or counter and the value in the operand of the application […]
Mitsubishi plc M: Auxiliary relay (equivalent to the intermediate relay in the electrical diagram). His control method is the same as Y, but there is no output port, just a single device. Like Y, there are coils and normally open, normally closed contacts. When multiple control methods use the same type of Y. At this […]
M8013 oscillates in a one-second frequency cycle, that is, it is turned on once in one second. M8014 oscillates in a one-minute frequency cycle, that is, it is turned on once every minute. Two fixed frequency internal relays.
Ladder diagram: Press X0, M0 is energized and self-locked. At the same time, KT1 is turned on and Y0 is output. At this time, the motor is rotating 10S. When the 10S time is up, T1 disconnects YO, and M1 is powered on and locked. At the same time Y1 output, the motor is reversed. […]
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:
ALT instruction is alternate output Assume that Y0 is the indicator light. LDP X0 ALT Y0 At this time, Y0 is off, and when X0 is pressed, the indicator lights up. Press again to turn off the light, then press it again. It’s as simple as that, it will alternate output. This can also be […]
Mitsubishi PLC master control MC input method: When writing the MC master command, first press F8 to enter the input command format. Then write MC space N0, space Mx press the confirm button to complete; When the master control speed is fast, press F8 to input MCR, and the space Nx is confirmed and completed. […]
The main reason is that the program written by PLC has made mistakes, some of which may be logical errors, or may be input errors. You have to check it out. Programmable logic controller (programmable logic controller), which uses a class of programmable memory used in its internal storage program, executes user oriented instructions such […]
