Non-Volatile Parameters

After volatile parameters are configured, the function block sends a request for the configuration CRC to
the I/O module.
If this number matches the locally calculated value, then the configurations stored on the I/O module
match those set in the function block. If the numbers do not match, then all configuration commands are
sent and the CRC is requested again.
You can use the PLUS+1 ® Service Tool to access all non-volatile parameters on the I/O module.

Timing Configurations

Timing for messages to and from the I/O module is established after all other configurations are sent.

CAN Bus Load

Adjust the average amount of message transmissions on the CAN bus to allow for bursts and other
increased message transmission situations.
Any CAN bus has a maximum message transmission capacity. So, to allow for situations that can cause
increases in messages, minimize the CAN bus load.
The CAN bus load is the average amount of message transmission on a CAN bus. Use the PLUS+1
USB/CAN gateway and CANKing software to view CAN bus loads.
PLUS+1 ® I/O modules communicate with their associated controllers over a CAN bus. System developers
can adjust I/O module RepTime and TimeOut parameters to manage CAN bus loading. Increasing these
times reduces the CAN bus load. Decreasing these times increases CAN bus load.
The function block uses the following message identifiers to enable communication between the
controller and the I/O module.
