Connections Chapter 1
If you are And you And Then
Uninhibit a module (clear the check box) No fault occurs A connection is made to the module and the module is dynamically reconfigured (if the
controller is the owner-controller) with the configuration you created for that module. If the
controller is configured for listen-only, it cannot reconfigure the module.
Fault occurs A connection is not made to the module. The module status information changes to indicate
the fault condition.
Follow these steps to inhibit or uninhibit a module from logic.
1. Use a Get System Value (GSV) instruction to read the Mode attribute for
the module.
2. To inhibit the module, set bit 2. To uninhibit the module, clear bit 2.
3. Use a Set System Value (SSV) instruction to write the Mode attribute back
to the module.
Example: Inhibit a Connection
If Module_1_Inhibit = 1, then inhibit the operation of the I/O module named Module_1.
1.
The GSV instruction sets Module_1_Mode = value of the Mode attribute for the module.
2. The OTE instruction sets bit 2 of Module_1_Mode = 1. This means inhibit the connection.
3. The SSV instruction sets the Mode attribute for the module = Module_1_Mode.
