First steps Power supplies with EtherCAT

1. Install the power supply as described in the chapter "Technical data, mounting, wiring" and connect it to the controller.
2. Install the TwinCAT automation software and familiarize yourself with the program.
3. Integrate the power supply into your TwinCAT project as described in the chapter "TwinCAT Quickstart". Further information on the software and communication via EtherCAT can be found in the chapters:
"TwinCAT development environment" and
"General commissioning instructions for the EtherCAT slave".
4. Configure the power supply in TwinCAT.
Select the process data as described in the chapter "Switching the process data sets".
Create a PLC project as described in the chapter "Programming the PLC".
Link the process data with PLC variables (see chapter "Linking the process data").
5. Select additional info data (see chapter "Selecting info data")
6. Optional: application-specific settings via the CoE directory
Set warning thresholds for the warning bit (see chapter "Setting the warning thresholds for the warning bit")
Reset counters and maximum/minimum values via the CoE directory (see chapter "Resetting counters and maximum/minimum values").
For parallel use, observe the notes on parallel use.
7. Monitor the output voltage using the DC-OK function.
8. Errors and warning messages
Read error and warning messages via the Diag History (see chapter "Displaying errors and warning messages").
Use the WCState bit to check whether errors have occurred during EtherCAT transmission (see chapter "Detecting invalid data").

Notice

First steps Power supplies with EtherCAT 1:

Parameterization via the CoE list (CAN over EtherCAT)

The EtherCAT device is parameterized via the CoE - Online tab (with a double click on the respective object) or via the Process Data tab (assignment of PDOs). A detailed description can be found in the EtherCAT System-Documentation in chapter “EtherCAT subscriber configuration”

Please note the general CoE notes in the EtherCAT System Documentation in chapter “CoE-interface” when using/manipulating the CoE parameters:
- Keep a startup list if components have to be replaced
- Differentiation between online/offline dictionary,
- existence of current XML description
- use "CoE reload" for resetting changes

First steps Power supplies with EtherCAT 2:

Process data of the PS2001-xxxx-1001 power supply

The process data objects (PDO) are cyclically transmitted process values. They are enabled via the "Process data" tab and then displayed in the TwinCAT tree. This allows them to be linked directly to variables from the PLC program.

  • By default, the following process data is recorded for the PS2001-xxx-1001 power supplies and updated and transmitted by the device every 2 ms:
  • After activating PDO 0x1600 "PSU Outputs", the power supply output can be disabled via the "Disable output" bit (see chapter "Switching output via EtherCAT").
  • Additional voltage, current and temperature information can also be transmitted as process data via the freely configurable information data "Info data 1" and "Info data 2". Further information can be found in chapter Selecting the info data.
