1. internal counter C The internal counter counts the internal signals (such as X, Y, M, S, T, etc.) when performing the scan operation. The connection and disconnection time of internal input signal should be longer than that of PLC. (1) the 16 bit increase counter (C0 ~ C199) is 200 points, of which C0 … Continue reading How to use counter C and auxiliary relay M in MITSUBISHI PLC programming
A cylinder pushes the cylinder two times. How do we use the counter C to complete it? First choose the condition, that is to say which input signal to count, I see the cylinder limit position sensor on the line, the cylinder is in place after the sensor bright, that is, the input signal, … Continue reading How to use the C counter in MITSUBISHI PLC
Parallel the Y0 and C0 at the output end. When the Y0 triggers the output once, the C0 will count once. The counter must have a reset instruction. Technology completion triggers RST C1 reset If you want to display the count times on the touchscreen, use the MOV command to send the C1 count to … Continue reading How to count the MITSUBISHI PLC counter
The MITSUBISHI PLC special auxiliary relay has 256 points, which are used to represent some of the states of the PLC, providing clock pulses and signs (such as the carry, the bit of the bit), setting the running mode of the PLC, or for the step control, the prohibition of interruption, the setting counter is … Continue reading All special auxiliary relays of FX series PLC
“PROG.E” LED flashes, it is an error indication. The light LED flashes when the timer, the constant of the counter, the circuit, the battery voltage, the abnormal noise, the conductive foreign object, and the contents of the program memory are changed. Please check the program again to check whether there is any conductive foreign matter … Continue reading Proge alarm for MITSUBISHI PLC
RST is an abbreviation of Reset. This is a reset instruction for resetting the state of the bit device to the off state and resetting the state of the timer and counter and data register to 0. The 20 basic instructions of PLC: LD: instruction fetch (normally open contacts) LDI: Reverse instruction (normally closed contact) … Continue reading What does RST in the Mitsubishi plc instruction mean?
