The GP-IB Interface Unit is
operating in Master mode (as
the Controller) and it is set to
trigger an interrupt program,
but the interrupt program in the
PLC does not start when an
SRQ message is received.
A non-fatal interrupt task error
occurred due to duplicate
refreshing.
(The Interrupt Task Error Flag,
A40213, is ON.)
---
IORD(222) is being used to read data from
the GP-IB Interface Unit in an interrupt task.
Problem
The GP-IB Interface Unit is mounted in an
Expansion Rack. The Unit must be
mounted in the CPU Rack in order to use
the interrupt program.
There is no task in the CPU Unit with the
SRQ interrupt task number specified in the
allocated DM area word (bits 00 to 07 of
m+6). Create an interrupt program.
The CPU Unit is not operating. The CPU
Unit must be in RUN or MONITOR mode.
An error will occur if the Unit’s I/O is
refreshed from the interrupt task while it is
being refreshed by cyclic I/O refreshing
(duplicate refreshing).
Change the PLC Setup (the Special I/O
Unit Cyclic Refreshing settings) to disable
cyclic I/O refreshing for the GP-IB Interface
Unit.
