3) If two or more DHCMOV instructions are used in one input interrupt program, only the first instruction (just after
the interrupt pointer) is executed when the interrupt is generated.
The rest of the interrupt, including additional DHCMOV instructions, is executed according to normal interrupt
processing.
Do not use M8394 as the command contact for the DHCMOV instructions following the first.
4) It is not permitted to use DHCMOV instruction for the same counter in two or more input interrupt programs.
5) While input interrupts are disabled by the interrupt disable flags (shown in the table below), DHCMOV instructions
are not executed when they are placed inside a corresponding interrupt.
*1.Cleared when the PLC mode is changed from RUN to STOP.
6) If an input interrupt is generated while input interrupts are disabled by something other than the interrupt disable
flags M8050 to M8055 (after execution of DI instruction and before execution of EI instruction), DHCMOV
instruction is immediately executed, but execution of the interrupt program is held. The interrupt program will be
executed after EI instruction is executed and interrupts are enabled.
Function change depending on the version
The function of FNC189 instruction changes depending on the version as shown in the table below.
