Operational Cycle (SAP Library - Work Clearance Management (PM-WCM))

Operational Cycle

Purpose

The operational cycle is used to describe the operational processing of lockout/tagout.

The operational cycle is divided into the following operational phases:

Tagging phase
Temporary untagging phase
Untagging phase

In the operational cycle, the items in an Operational WCD run through several statuses for each operational phase in a specific sequence.

The first status within each operational phase serves notice of an activity, that is, the change of an operational condition/type:

Tag
Untag temporarily
Untag

If an operational tag is printed, the status that confirms printing is assigned.

Tag printed
Test tag printed

Note

As well as operational tags, you can also print operational lists.

The last status confirms the execution of an activity on site:

Tagged

Temporarily untagged
Untagged

The following diagram illustrates the maximum pre-defined operational cycle:

This graphic is explained in the accompanying text

The following operational cycles are possible:

Tagging cycle with temporary untagging phase

This operational cycle consists of the tagging phase, temporary untagging phase and untagging phase.

Tagging cycle without temporary untagging phase

This operational cycle consists of the tagging phase and untagging phase.

Test cycle

This operational cycle consists of the tagging phase and temporary untagging phase.

You can further reduce the operational cycle. For example, you can hide statuses, such as Tag, Untag or Test tag printed. The processes for this status are then performed completely in the background. For the minimum set-up of the operational cycle, only the statuses of the user that confirm the execution of the activity on site must be set.

Progress in the operational cycle is displayed in the item and the header for the Operational WCD:

If all the items have the same operational status, this operational status is also displayed in the header.

If only one conflict during the switch , this is displayed in the header.

Prerequisites

To start switching, the Operational WCD must have the status PREP (Prepared).

Process Flow

The system executes checks and simulations for every operational step.

You can still change the untagging condition/type (or temporary untagging condition/type) of an item until you enter the respective untagging phase (or temporary untagging phase). However, when the activity is notified, it is automatically frozen.
