DM 6144 to DM 6655 cannot be used for D.
When the execution condition is OFF, MOV(21) is not executed. When the
execution condition is ON, MOV(21) copies the content of S to D.
Source word
TC numbers cannot be designated as D to change the PV of the timer or counter.
You can, however, easily change the PV of a timer or a counter by using
BSET(71).
ER: Indirectly addressed DM word is non-existent. (Content of
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when all zeros are transferred to D.
The following example shows @MOV(21) being used to copy the content of
IR 001 to HR 05 when IR 00000 goes from OFF to ON.
