13. Set the module RPI. This is how often the module’s scheduled data
is updated in the processor. The value can range from 0.2 to 750 ms.
The default is 5 ms.
14. Click Finish >> to complete the module configuration.
Using the Configuration Signature
The Remote I/O configuration program computes a configuration
signature that is a CRC based on the current I/O configuration. The
purpose of the configuration signature is to ensure that the remote I/O
configuration stored in flash memory on the 56AMXN is the correct one.
Otherwise, your ControlLogix program may be reading from or writing
to incorrect locations.
You enter the configuration signature from the configuration program in
the module configuration data area (Local:slot#:C:Data[0] to
Local:slot#:C:Data[3]) in RSLogix 5000 to ensure that the I/O
configuration on which the ControlLogix program is based matches the
configuration on the module.
If the Configuration Signature in the RSLogix 5000 program doesn’t
match the configuration signature on the module, the module returns a
key segment mismatch error to the ControlLogix when the ControlLogix
processor tries to open a connection to the module.
If the connection is already open and you change the Configuration
Signature in the ControlLogix Configuration data area, it has no effect
