Function
When a Special I/O Unit Setting Error occurs,
A40202 and the bit in these words corresponding to
the Unit's unit number are turned ON. Bits 00 to 15
correspond to unit numbers 0 to F.
1: Setting error
0: No setting error
(Bits A42800 to A43315 correspond to unit numbers
000 to 05F (0 to 95).)
The CPU Unit will continue operating and the ERR/
ALM indicator on the front of the CPU Unit will flash.
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.)
When a pulse output stop error occurred with pulse
output 0, the corresponding error code is written to
this word.
When a pulse output stop error occurred with pulse
output 1, the corresponding error code is written to
this word.
