Function
If a Pulse Output Stop Error occurs
for pulse output 3, the error code is
stored.
Contains the Maximum Interrupt
Task Processing Time in units of
0.1 ms.
(This value is written after the inter-
rupt task with the max. processing
time is executed and cleared when
PLC operation begins.)
Contains the task number of the
interrupt task with the maximum pro-
cessing time. Hexadecimal values
8000 to 80FF correspond to task
numbers 00 to FF. Bit 15 is turned
ON when an interrupt has occurred.
(This value is written after the inter-
rupt task with the max. processing
time is executed and cleared when
PLC operation begins.)
If a Pulse Output Stop Error occurs
for pulse output 0, the error code is
written to this word.
If a Pulse Output Stop Error occurs
for pulse output 1, the error code is
written to this word.
Stores the results of comparing data
in the Memory Cassette and CPU
Unit. This information is cleared the
next time the Memory Cassette is
accessed normally (initialized, writ-
ten, read, or compared).
