Commissioning
"bShutdownActive" indicates that a stop or shutdown is being executed.
"bUpsReady" indicates that the UPS is providing the output voltage.
"b24VInOK" reports that the UPS is being supplied with 24 V input voltage.
Note
The function block gives the PLC program full control over the behaviour of the UPS. De-
pending on the operating mode, the developer must see to it that the system is in the de-
sired state when switched off, and/or that the system behaves correctly when it restarts.
Problems that can occur include, for instance:The system has halted, the UPS however
provides voltage again -> the system remains inert, even though a power supply is
present.The system starts again, but the UPS is still in the discharge phase, and does not
switch off until fully discharged -> the system starts up, but then is powered down without
warning.
