Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
Destination operand D2 (system work area) uses 2 data registers starting with the operand designated as D2. Data registers
D0 through D1298 and D2000 through D7998 can be designated as D2. The two data registers are used for a system work
area. Do not use these data registers for destinations of other advanced instructions, and do not change values of these data
registers using the Point Write function on
operate correctly.
The dual timer instructions cannot be used in an interrupt program. If used, a user program execution error will result,
turning on special internal relay M8004 and the ERR LED on the CPU module.
