A437 Number of Connected
Units
Stores the number of Expansion Units
and Expansion I/O Units connected as
a hexadecimal number.
Note This information is invalid only
when a Too Many I/O Points error
has occurred.

0000 to 0006 hex Retained Cleared
A440 Max. Interrupt Task
Processing Time
Contains the Maximum Interrupt Task
Processing Time in units of 0.1 ms.
Note This value is cleared when PLC
operation begins.
0000 to FFFF hex Cleared Cleared Written after
the interrupt
task with the
max. process-
ing time is exe-
cuted.
A441 Interrupt Task with
Max. Processing Time
Contains the task number of the inter-
rupt task with the maximum processing
time. Hexadecimal values 8000 to
800F correspond to task numbers 00 to
0F. Bit 15 is turned ON when an inter-
rupt has occurred.
Note This value is cleared when PLC
operation begins.

the interrupt
task with the
max. process-
ing time is exe-
cuted.

Contains the Total Interrupt Task Pro-
cessing Time in one cycle in units of
0.1ms.Sets when the value is bigger
than the last one once a cycle by com-
mon processing.
Note This value is cleared when PLC
operation begins. The value is
unstable for CPU Unit version 1.0
or earlier.
