Input Size
Input size is the length of the data sent from the I/O module (target) to the GuardPLC controller (scanner). The value in
this field is predetermined by the module type and cannot be changed.
Output Size
Output size is the length of the data sent from the GuardPLC controller (scanner) to the I/O module (target). The value in
this field is predetermined by the module type and cannot be changed.
Configuration
Size
Configuration Size is the size of the configuration data sent with the connection establishment request.
Input Address
The Input Address is the offset in words of the GuardPLC input scanner assembly where the GuardPLC controller will
store the input data from the target device. Enter the Input Address.

TIP
If you get a ‘Type’ error and the save procedure is
aborted, it is most likely a data type error with the
signals in the RSLogix Guard PLUS! software scanner
configuration. Make sure that you have not tried to cross
a data type boundary or that you have not used a module
with an odd number of bytes with INT or WORD data
types.
