Setting Exposed Variables

This section describes how to expose Safety CPU Unit variables to the Communication Control Unit.
Exposed Safety CPU Unit variables (exposed variables) appear in the I/O Map of the Communication
Control Unit.
Use one of the following methods to set exposed variables.
• Register new variables on the Exposed Variables Tab Page.
• Select global variables on the Exposed Variables Tab Page.
• Set the Expose Column for global variables.
• Copy global variables and paste them on the Exposed Variables Tab Page.
The procedures for these methods are given below.
Precautions for Correct Use
• If you change the I/O of exposed variables, the device variable assignments to the Communi-
cation Control Unit will be canceled. In this case, you need to assign the device variables
again, and then transfer the settings to the Communication Control Unit.
• If you change exposed variables, you need to transfer the settings to the Communication
Control Unit. After you transfer the settings, check that the operation of the Communication
Control Unit is correct.
Registering New Variables on the Exposed Variables Tab Page
Use the following procedure to register variables on the Exposed Variables Tab Page when those vari-
ables are not registered as global variables. The registered exposed variables are automatically regis-
tered as global variables.
1
Double-click Exposed Variables under Configurations and Setup – Communications –
Standard – Slave I/O.
The Exposed Variables Tab Page is displayed.
