Syntax
PDLDAT(ptname,minon,minoff,maxoff,kwval)
ptname | Point name of the load. |
minon | Minimum time (in minutes) that the load must remain ON after PDL has restored it. - This parameter must be less than 546 and can be defined as a decimal, integer, point name, or a local variable. |
minoff | Minimum time (in minutes) that the load must remain OFF before PDL can restore it. - This parameter must be less than 546 and can be defined as a decimal, integer, point name, or a local variable. |
maxoff | Maximum time (in minutes) that PDL can keep the load off after shedding it. - This parameter can be a decimal, integer, point name, or a local variable. - The maximum allowable value of maxoff is (minoff + 546). |
kwval | Kilowatt value for the load. - This parameter can be a decimal, integer, point name, or a local variable. |
Use
Defines the minimum on-time, minimum off-time, maximum off-time, and kilowatt value for a specific load.
A group of PDLDAT commands in a load handling automation station are controlled by a single PDL command that defines load parameters and maintains a certain level of kilowatt use (or target) for a group of loads.
Example

118 PDLDAT(FAN17,10,5,180,10)
Notes
- In a network system, a load defined by a PDLDAT statement must reside in the same automation station as the PDL statement.
- A PDLDAT statement is referenced by only one PDL statement. Using multiple references produces unpredictable results.
- The PDLDAT statement should be in the same automation station as the load.
