Replacing the Active Module of a Pair of Dual-Redundantly Configured
Modules
It is necessary to switch the control right from the running module to the standby module adja-
cent to it. Thus replacing the module can be performed with the following two steps.
•
Step 1. : Switch the control right of the dual-redundantly configured module. (As descri-
bed in the following section, "Switching Control Right ")
• Step 2. : Replace the module using the same procedure as replacing a standby module.
(As described in previous section, "Replacing the Standby Module of a Pair of Dual-Re-
dundantly Configured Modules")
When the I/O modules are dual-redundantly configured, if the active I/O module is severed
from the field connections, the related safety loop maybe af
fected.

Switching Control Right
The control right can be switched from the active module to the standby module.
•
A tool for switching the control right of the dual-redundantly configured I/O modules is
available on SENG,
• To use this tool, the security level "1" is required
Do not remove the cables or terminal blocks from the active modules. Though removing the
cable or terminal block may force the control right to be switched to standby modules, IOP
occurs and the relevant loops may be shutdown.
