12.2.1.2 Mark VIeS Safety I/O Pack Replacement (Upgraded Hardware Form)
Attention
If upgrading to YVIBS1B from an existing YVIBS1A configuration, be sure to correct
the GAP12 configuration using ToolboxST. Refer to the sections YVIB Compatibility
and YVIB I/O Upgrade for further details.
Attention
Redundant Safety I/O packs mounted on the same terminal board must all be of the
same hardware form, and running the same firmware version.
Do NOT attempt this replacement unless there are enough I/O packs with the newer
hardware form available, including spares.
Note It is recommended to backup the ToolboxST .tcw system file prior to upgrading the system.
➢➢ To replace a Mark VIeS Safety I/O Pack with an upgraded hardware form
1. Follow all site safety procedures.
2. Verify that the replacement I/O pack is compatible with one being replaced.
3. Verify that the site’s ControlST software version has been upgraded to V06.01 or later.
4. Remove the power connector on the side of the I/O pack(s).
5. Unplug the Ethernet cable(s) from the failed I/O pack(s) and mark their positions.
6. Loosen the two mounting nuts on the I/O pack threaded shafts.
7. Unplug the I/O pack(s).

controller.
