A524 00 to 15 Interrupt Counter 0
Counter PV
These words contain the interrupt counter PVs for interrupt input 0 to 3
operating in counter mode.
The counter PV starts decrementing from the counter SV. When the
counter PV reaches the 0, the PV is automatically reset to the SV.
Range: 0000 to FFFF

A401 09 Program Error Flag
(fatal error)
ON when program contents are incorrect.
Module operation will stop.
Module
A405 11 No END Error Flag ON when there isn’t an END(001) instruction in each program within a
task.
12 Task Error Flag ON when a task error has occurred. The following conditions generate
a task error.
There isn’t a program allocated to the task.
13 Differentiation Overflow
Error Flag
The allowed value for Differentiation Flags which correspond to differ-
entiation instructions has been exceeded.
14 Illegal Instruction Error
Flag
ON when a program that cannot be executed has been stored.

00 to 15 Error Log Area When an error has occurred, the error code and error contents are
stored in the Error Log Area.
Module
A408 00 to 15 Error Log Pointer When an error occurs, the Error Log Pointer (binary) is incremented by
1 to indicate the location where the next error will be recorded as an
offset from the beginning of the Error Log Area (A100 to A199).
