Operational WCD
Definition
A work clearance document that is used for the lockout/tagout of technical objects and can therefore be switched.
Use
An Operational WCD can be created both from another Operational WCD and from a WCD template . In this case, the data from the template is copied completely and is available for further processing.
The advantage in creating from a WCD template is that these are of higher quality. When you copy data from another Operational WCD, you should pay particular attention, especially to altered untagging conditions.
The Operational WCD is assigned a usage at header level. The usage controls the operational processing of the lockout/tagout. You can use different usages to control different operational cycles . The operational cycle is the same for all the items of a work clearance document, because the assignment is made at header level. You can make the switch within the operational cycle dependent on the issue of an approval . This allows you to ensure that the approvals necessary for the switch are issued.
Structure
The Operational WCD is subordinate to the work clearance applications .
Note the following assignment rule:
A work clearance application can be assigned to several Operational WCDs, and vice versa (assignment rule R2).

In addition to the system statuses that apply for all WCM objects , the following system statuses are also possible for the Operational WCD:
ID |
Name |
Description |
|---|---|---|
PROC |
In process |
The switching has begun. |
UNT |
The Operational WCD can be untagged. This status can be reset. |
|
TEST |
One test cycle is allowed for the Operational WCD. This status can be reset. |
The following table contains the possible system statuses both of the header and of an item of the Operational WCD:
ID |
Name |
Description |
|---|---|---|
ITG |
Initial status |
Initial status for an item to be switched |
BTG |
Tag |
Initial status of tagging phase |
PTAG |
Print status of tagging phase |
|
ETG |
Tagged |
Final status of tagging phase Status cannot be suppressed Item cannot be deactivated |
BTUG |
Untag temporarily |
Initial status of temporary untagging phase Item cannot be deactivated |
PTST |
Print status of temporary untagging phase Item cannot be deactivated |
|
ETUG |
Temporarily untagged |
Final status of temporary untagging phase |
BUG |
Untag |
Initial status of untagging phase Item cannot be deactivated |
EUG |
Untagged |
Final status of untagging phase |
CONF |
Conflict for item to be switched was bypassed. |
|
MOBI |
Data on mobile device |
The item is copied to a mobile device. Therefore it can no longer be switched in the back end. Item cannot be deactivated |
In addition to the system statuses that apply to the header and to the item, the following system statuses can also occur in the item of the Operational WCD:
ID |
Name |
Description |
|---|---|---|
POST |
Postscript |
Item was added subsequently in change mode |
PROT |
Operational protection was set for the item to be switched |
|
INAC |
Object deactivated |
The item to be switched is inactive. No more changes/activities allowed Status cannot be reset This status is equivalent to the deletion of an item as soon as the work clearance document is prepared. |
