7. Once you have set these properties, click the OK button to
apply the changes.
RSNetWorx for EtherNet/IP software displays these changes in

8. Repeat steps 5 … 7 for all target I/O modules and press the Save
button to download the connection configuration to the
GuardPLC controller.
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.
Output
Address The Output Address is the offset in words of the GuardPLC controller’s scanner output assembly buffer where the
GuardPLC controller will store its data before sending it to the target device, in this case the FLEX I/O module.
Property Description
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.
