Softplc - WEG CFW501 V1.8X Programming Manual

17 SOFTPLC

The SoftPLC function allows the inverter to assume PLC (Programmable Logical Controller). For further details
regarding the programming of those functions in the CFW501, refer to the CFW501 SoftPLC manual. Below are
described the parameters related to the SoftPLC.
P1000 – SoftPLC Status
Adjustable 0 = No App.
Range: 1 = Installing App.
2 = Incompat. App.
3 = App. Stopped
4 = App. Running
Properties: ro
Access groups HVAC
via HMI:
Description:
It allows the user to view the status in which the SoftPLC is. If there are no applications installed, the parameters
P1001 to P1079 will not be shown on the HMI.
If this parameter presents the option 2 ("Incompat. App."), it indicates that the version that was uploaded to the
flash memory board is not compatible with the present CFW501 firmware.
In this case, it is necessary that the user recompile the project on the WLP, considering the new CFW501
version and redo the download. The user can also upload the application from the inverter to a PC via WLP,
provided that the application password is known, or that the application has no password associated.
P1001 – Command for SoftPLC
Adjustable 0 = For application
Range: 1 = Executes application
2 = Excludes application
Properties: cfg
