The following tables show the Auxiliary Area words and bits that are related to
the CJ1M CPU Unit's built-in inputs. These allocations apply to CPU Units
equipped with the built-in I/O only.
■ Interrupt Inputs
Description
Used for interrupt input 0 in counter mode.
Sets the count value at which the interrupt task
will start. Interrupt task 140 will start when inter-
rupt counter 0 has counted this number of
pulses.
Used for interrupt input 1 in counter mode.
Sets the count value at which the interrupt task
will start. Interrupt task 141 will start when inter-
rupt counter 1 has counted this number of
pulses.
Used for interrupt input 2 in counter mode.
Sets the count value at which the interrupt task
will start. Interrupt task 142 will start when inter-
rupt counter 2 has counted this number of
pulses.
Used for interrupt input 3 in counter mode.
Sets the count value at which the interrupt task
will start. Interrupt task 143 will start when inter-
rupt counter 3 has counted this number of
pulses.
These words contain the interrupt counter PVs
for interrupt inputs operating in counter mode.
In increment mode, the counter PV starts incre-
menting from 0. When the counter PV reaches
the counter SV, the PV is automatically reset to
0.
In decrement mode, the counter PV starts dec-
rementing from the counter SV. When the
counter PV reaches the 0, the PV is automati-
cally reset to the SV.
