Goodrive600 Series VFD Auto Station Programmable Card
4 Auto Station programming interfaces
The PLC card integrates the secondary development function by using the Auto Station. In
addition to the functions equipped with the PLC card, the entrance parameters required for
Auto Station programming also include the PLC card hardware functions, VFD hardware
functions, and VFD parameters. The output of Auto Station programming results is not only
for the internal use of the PLC card, but also for other control purposes such as controlling the
hardware output interfaces of the PLC card, the hardware output interfaces of the VFD, and
the start and stop commands of the VFD.
This chapter describes the relationship between the Auto Station secondary development,
PLC card, and VFD interfaces (including hardware and software instructions), with a focus on
Auto Station programming interfaces. The VFD related functions of Auto Station
programming interfaces are valid only when the SW1 is in Run state.
If not otherwise specified, all programming instructions use the LD programming system.
4.1 Importing and exporting interfaces
You can define programming interfaces and export the interface data to an Excel file. The
Auto Station can provide programming interfaces by importing the Excel interface file. We
provide a default programming interface file (an Excel file), which contains the interface
names and corresponding PLC elements (D elements). You can use D elements for
programming regardless of whether you import an Excel file. The default Excel file for GD600
programming interfaces is GD600_PLCcard_V100.xls.
In the Excel file, each variable is named in the format of I/C_xx, in which I indicates the
variable is sent to the PLC card through the VFD, while C indicates the variable is sent from
the PLC card to the VFD. In a word, the initial letter identifies the variable type.
The PLC card provides data storage elements of 8000 words, D0–D7999, in which D7400–
D7699 are defined as the VFD data transfer interfaces that have special meanings
corresponding to GD600 VFD parameters and therefore cannot be used as common storage
elements and the other D elements can be used as required.
The method of importing programming interfaces is as follows:
1. Double-click Global variable table on the Project Manager bar. In the opened global
variable table,
GD600_PLCCard_V100.xls.
