If any of the lower limits for the DM ranges are set to “0000,” the correspond-
ing output bits are turned ON when the counter is reset.
The reversible drum counter is a ring counter with a counting range of 0000
to 9999. It requires three input signals to operate: a count input, reset input,
and UP/DOWN selection input. For these inputs, SR bits 1804 to 1806 are
reserved and cannot be used for any other purpose while the RDM(60) is
being used.
Operation is enabled when RDM(60) is executed with an ON execution con-
dition. RDM(60) increments when the UP/DOWN selection input (1806) is
OFF. When this input is ON, RDM(60) decrements. Incrementing or decre-
menting occurs on the rising edge of the count input signal. When RDM(60)
is executed by the CPU, the value in the counter buffer is transferred to CNT
46.
