Troubleshooting
Find out how to ensure the outputs of the I/O module function properly, and make sure your changes to
parameters are saved.
Problem
Cause
Solution
Outputs of I/O module do not
function as expected. Configured is
always false.
The I/O module is using variable address mode
and the CAN shield voltage does not fall within
the range matching the function block’s N1
value.
Use the
I/O Module CAN Message Identifiers
table to find the
correct voltage and ensure it is applied to the CAN shield
during power up.
Change the N1 value in the function block to match the
voltage applied to the CAN shield.
Incompat_HW is true. The function block is
communicating with a device other than the I/O
module.
Ensure the proper addressing mode and corresponding
communication parameters are set on both the I/O module
and the function block.
It is possible the I/O module is correctly configured, but a
second I/O module has a similar configuration. Review
configuration and make changes to the other I/O modules.
Incompat_Protocl is true. The firmware on the
I/O module uses a version of the I/O Protocol less
than 2.00.
Update the I/O module with the latest firmware.
Incompat_Protocl is true. The firmware on the
I/O module uses a version of the I/O Protocol
later than version 2.99.
Replace the function block by using the latest available
HWD file.
When changing the I/O module ’s
parameters with the PLUS+1
®
Service
Tool, those changes are not properly
saved.
A function block detects the changes and resets
the parameters to the values specified in the
function block.
Disconnect the function block’s controller before making
parameter changes. If the changes do not result in different
CAN message identifiers for the I/O module, then
reconnecting the controller results in the parameters
reverting back to the values set in the function block.
