b) High-speed counter interrupts: 8 points including I010, I020, I030, I040, I050, I060, I070, and
I080. (used with API 53 DHSCS instruction to generate interrupt signals)
c) Communication interrupts: 3 points including I140, I150 and I160
d) Associated flags:
Flag
Function
M1050
Disable external interruption I000 / I001
M1051
Disable external interruption I100 / I101
M1052
Disable external interruption I200 / I201
M1053
Disable external interruption I300 / I301
M1054
Disable external interruption I400 / I401
M1055
Disable external interruption I500 / I501, I600 / I601, I700 / I701
M1056
Disable timer interrupts I605~I699
M1057
Disable timer interrupts I705~I799 and I805~I899
M1059
Disable high-speed counter interruptions I010~I080
M1280
I000/I001 Reverse interrupt trigger pulse direction (Rising/Falling)
M1284
I400/I401 Reverse interrupt trigger pulse direction (Rising/Falling)
M1286
I600/I601 Reverse interrupt trigger pulse direction (Rising/Falling)
Note: Default setting of I000(X0) is falling-edge triggered. When M1280=ON and EI is enabled,
PLC will reverse X0 as rising-edge triggered. To reset X0 as falling-edge, reset M1280 first
and execute DI instruction. After this, X0 will be reset as falling-edge when EI is executed
again.
Program example:
During the PLC operation, the program scans the instructions between EI and DI, if X1 or X2 are
ON, the subroutine A or B will be interruptted. When IRET is reached, the main program will
resume.
