Function
When A40213 is ON, the content of these bits
depends upon the status of A42615 (the Interrupt Task
Error Cause Flag).
1) A42615 OFF:
An interrupt task was executed for more than 10 ms
during I/O refreshing of a C200H Special I/O Unit or
a SYSMAC BUS Remote I/O Unit. A42600 to
A42611: contain the interrupt task number.
2) A42615 ON:
An attempt was made to refresh a Special I/O Unit's
I/O from an interrupt task with IORF(097) while the
Unit's I/O is being refreshed by cyclic I/O refreshing
(duplicate refreshing). A42600 to A42611: contain
the Special I/O Unit's unit number.
Task number: 000 to 0FF (0 to 255)
Unit number: 000 to 05F (0 to 95)
These bits will be cleared when the error is cleared.
When A40213 (the Interrupt Task Error Flag) is ON,
this flag indicates the cause of the error. The CPU Unit
will continue operating and the ERR/ALM indicator on
the front of the CPU Unit will flash.
A42615 will be ON if a Special I/O Unit was refreshed
from the interrupt task while it was already being
refreshed.
A42615 will be OFF if the interrupt task was executed
for more than 10 ms during I/O refreshing of a C200H
Special I/O Unit or a SYSMAC BUS Remote I/O Unit.
1: Duplicated refreshing
0: Interrupt task executed over 10 ms
When an CPU Bus Unit Setting Error occurs, A40203
and the bit in this word corresponding to the Unit's unit
number are turned ON. Bits 00 to 15 correspond to
unit numbers 0 to F.
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash.
1: Setting error
0: No setting error
If a Special I/O Unit Setting Error occurs (i.e., when
A40202 turns ON), the bit corresponding to the unit
number will turn ON. The CPU Unit will continue oper-
ating and the ERR/ALM indicator on the front of the
CPU Unit will flash.
Bits A42800 to A43315 correspond to 00 to 5F (unit
numbers 0 to 95).
Contains the Maximum Interrupt Task Processing
Time in units of 0.1 ms.
(This value is written after the interrupt 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 processing 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 interrupt task with the
max. processing time is executed and cleared when
PLC operation begins.)
Indicate whether PLC Link Units are mounted to the
PLC as follows:
A44211: PLC Link operating level 1
A44212: PLC Link operating level 0
1: Unit mounted
0: Unit not mounted
