PMs

PMs are scheduled maintenance records for an agency's assets. Lucity supports various types of PMs and types of schedules for PMs.

PM types

PM Type	Schedule	Function
Standard PM	Has one schedule that applies to all assets.	Generates one Work Order for all listed assets.
Grouped PM	Has individual schedules for each group and asset.	Generates a Work Order for each asset, based on that asset's individual schedule.
Grouped Asset PM	Has individual schedules that apply to each group of assets.	Generates a Work Order for each group of assets based on that asset group's individual schedule.
Tightly Linked PM	Links to a Standard PM or PM Group and replaces it at designated intervals.	Generates one Work Order for all listed assets.
Affected PM	Links to a Standard PM or PM Group and generates in addition to the linked PM at designated intervals.	Generates one Work Order for all listed assets.
Out of Service PM	Has a Floating Schedule that generates based on an asset's operational status.	Generates a Work Order for an asset that is Out of Service (Status > 950). This type of PM targets a part of the Plant/Process Equipment hierarchy.

PM schedules

Fixed Schedule - Generates work at a set date interval between the start of one Work Order and the start of the next, regardless of when the last job was completed.
Floating Schedule - Generates work with a set date interval between the end of a Work Order and the beginning of the next.
Meter Based Schedule - Generates work with a set meter reading interval between the end of a Work Order and the beginning of the next.
Mixed Schedule - Generates work on either a floating schedule or meter based schedule, whichever generates first.
Tightly Linked Schedule - Generates work based on work completed by a linked PM. This type of schedule doesn't set when the work will generate. Instead, it indicates how often the PM will replace a PM that it is linked to.

PM processing

Lucity regularly checks PMs to see if they are due to generate a Work Order. The following are ways that the PMs are processed:

Automatic PM generation - Lucity Services automatically initiates the system process to check all PM records to see if the schedule is due. This is the primary method of generating PMs. More information about Lucity Nightly Processes.
Closing a related Work Order - When the Work Order is closed, the PM is rescheduled and the system checks to see if the new schedule is due. More information about the PM/Work Order relationship.
Editing the PM record - When the PM is edited and saved, the system checks to see if the schedule is due.
Manual PM processing - The Admin Portal > Tasks > Force Run PM Processing tool prompts the system to check all PM records to see if the schedule is due. This is useful if system problems occurred overnight.
