CPU Restrictions and Open Issues
Subject Description
Timing Issue with ALG220/221-F or
earlier modules may result in
incorrect %AI values read by CPU
The %AI values reported by an IC693ALG220/221-F or earlier
module revision may be incorrect and exhibit erratic behavior.
Certain current or voltage levels within the input range applied to
the module can cause the %AI values to be reported incorrectly.
The problem stems from the use of particular opto-couplers that
may exhibit timing issues with CPU 35x/36x modules.
This issue does not occur with IC693ALG220/221-G and later
module revisions.
The CPU may generate a fatal fault
if logic containing a DOIO function
block call to a smart module is
repeatedly transitioned between
RUN and STOP modes.
Storing program logic that contains a call to a DOIO function block
may cause the CPU to run out of system memory. This can occur
when the PLC transitions between RUN and STOP modes several
times.
Storing the hardware configuration will cause the system memory
to be freed, and the PLC will resume normal operation.
CPU may generate a Fatal Fault
during store of folders with large
configurations
The CPU may generate a fatal fault during a store of a folder with a
very large configuration. This may be made worse by storing logic
and configuration at the same time, or by read requests for
reference table data from a programmer or HMI during the store.
See “Storing Large Configurations” on page 6 for
recommendations.
Reading corrupted data from flash
memory may cause a Watch Dog
Timeout
If corrupted data is read from flash memory, the Watch Dog Timer
on the PLC may be triggered. This can be corrected by completing
a valid flash store.
The CPU may generate a fatal fault
when configuring a module with
the HHP following a store to the
PLC that exhausts user memory
The 90-30 PLC CPU may generate a fatal fault when the user
attempts to configure a module with the HHP after a store to the
PLC that exhausts user memory.
Firmware Update fails following
power-up with Clear M/T and a
write to flash
A firmware upgrade may fail after the user presses the Clear and
M/T keys on the HHP during power-up and then performs a write to
flash. Cycling power on the PLC will enable the upgrade to
proceed.
