7.34 MultiPumpType ObjectType Definition

The MultiPumpType provides Variables for Pump operation in a system with several Pumps and is formally defined in Table 76.

The optional Variables PumpCollectiveIDs, RedundantPumpIDs, and DistributionPriority are one dimensional arrays without a limit for possible entries.

The InstanceDeclarations of the MultiPumpType have additional Attributes defined in Table 77. The Variables and the associated Descriptions are based on the standard VDMA 24223.

BrowsePath Value Attribute Description Attribute
DistributionPriorityThis property describes in ascending order the priority of pumps in addition operation mode.
DistributionTypeThis property describes the share of operation time of different pumps of the pump system in addition operation mode.
ExchangeModeThis property specifies the exchange mode of the pump
ExchangeTimeThis property specifies the determination of the absolute time for the next exchange of the pump, if operator specific Pump Exchange Mode is activated.
ExchangeTimeDifferenceThis property specifies the determination of the time for the next exchange of the pump relative to ExchangeTime, if operator specific Pump Exchange Mode is activated.

Description: second [unit of time]

MaximumNumberOfPumpsInOperationThis property specifies the maximum number of pumps in operation. The difference between NumberOfPumps and MaximumNumberOfPumpsInOperation identifies the redundant pumps.
MultiPumpOperationModeThis property specifies the actual multi pump operation mode. In redundant operation mode a pump fulfils the process function of another pump. Addition operation mode characterizes the supplementary fulfilling of the process function. The mixed mode characterizes both operation tasks.
NumberOfPumpsThis property identifies the number of pumps in multi pump management
PumpCollectiveIDsThis element identifies the pumps within the pump system
PumpRoleThis property identifies the role rsp. task of the pump within the multi pump management.
RedundantPumpIDsThis property identifies the actual redundant pumps within the pump system
