you can Add a timer to stop.
Although the total stop is pressed, the user program in the plc is still running, and when the condition is satisfied, the corresponding result is output according to the user control program and the external input condition.
Should not be a problem with plc itself, most of which is caused by an abnormal external input signal.
X0 is released after pressing, and the M1 contact is output after 5 seconds.
X0 keeps pressing for 5 seconds and the M1 contact is output.
In the stepping program, the simpler way is to use the pause switch as the normally closed one as the next trigger condition in the stepping program, and the other trigger conditions are connected in series, but only if it is done at each step. Pause, not stop where you want to stop
Normally open input string m0 normally closed, press button m0 to set, the timer starts timing, and m0 is cleared after time
In the simulation-monitor mode – click-write mode – modify your program to be modified – click – compile – click – write to the PLC or F2
K1Y0=Y0 Y1 Y2 Y3
K2Y0=Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7
K3Y0=Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y10 Y11 Y12 Y13
K4Y0=Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y10 Y11 Y12 Y13 Y14 Y15 Y16 Y17
Mitsubishi inputs and outputs are due to octal, there is no 8 and 9.
Auxiliary relay M has 8 and 9, such as K4M0=M0 M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 M11 M12 M13 M14 M15
K4Y0 is 2 bytes y0-y17
K2Y0 is 1 bytes y0-y7
For example: [K85 K2Y000] Corresponds to k85 conversion binary 1010101 to the state of y0-y7.
In the Mitsubishi PLC program, it is often seen that K4M100, K7M500, K1X0, K2Y0, etc. are written.
KnM refers to consecutive 4n bits starting with M. For example, K4M100 is a continuous 4*4=16 addresses starting with M100, which means M100 to M115. These 16 bits are just the length of one word. If it is K7M500, it means 7*4=28 bits starting with M500, more than 16 bits, 32 bits of light rain, so double word instructions should be used when appearing in the program.
These are generally used to transfer instructions and compare instructions. The format used is generally as follows:
= K4M100 K0
The 16-bit contact comparison command, the M100-M115 has a total of 16 bits off, and the contact is turned on.
<> K4M100 K50
16-bit contact comparison command. When the value represented by the 16-bit word of M100-M115 is not equal to 50, the contact is turned on.
D= K7M500 K0
The 32-bit contact comparison command, the M500-M527 has a total of 28 bits off, and the contact is turned on.
MOV K0 K1Y0
16-bit transfer instruction, all of Y0-Y3 are reset.
MOV K2X0 D0
The 16-bit transfer instruction, X0-X3, a total of 8 bits representing the value is transferred to D0.
DMOV K6M50 D50
The 32-bit transfer command, the value represented by 24 bits of the M50-M523 is transferred to the D50.
CMP K1X0 K1Y0 M10
16-bit comparison instruction, the data composed of X0-X3 is compared with the data composed of Y0-Y3, the former is larger than the latter, M10=1, the former = the latter, M11=1, the former is the latter, M12= 1.
DCMP K5X0 K5M0 M100
32-bit comparison instruction, the data composed of X0-X23 is compared with the data composed of M0-M23, the former is larger than the latter, M100=1, the former = the latter, M101=1, the former is the latter, M102= 1.
Required to replace the battery need Off power Operation, and should be completed within 3 minutes
1, Mitsubishi PLC programming cable communications port and baud rate are set correctly. Such as: Point Serial Icon -> port RS232-> baud 9.6k/bps-> OK -> then click communications test, if successful, displays the communication hardware connection is no problem.
2, Mitsubishi PLC Are there written procedures, or that the PLC is worked properly.
3, the program is encrypted, the program also lost.
4, Mitsubishi PLC whether damage.
