Configuring a safe communication channel

If a device with integrated safety option is controlled via PROFIsafe, you must configure the safe communication channel.

INFORMATION

This example describes the procedure for a configured and approved MOVISAFE® CSS21A safety option. The configuration of a safety option is described in the product manual of the respective device.

MOVISUITE® provides the following functions for safety options:

  • Startup of the safety sub-functions
  • Reading and partially writing safe F-parameters, such as F_iPar_CRC, F_WD_Time, etc.
  • Diagnosing PROFIsafe communication by monitoring F-process data
  • Diagnosing the PROFIsafe device (e.g. status messages and error messages)

INFORMATION

The safety options can also be configured without using MOVISUITE® via the MOVISAFE® F‑Protocol Editor configuration tool (see chapter MOVISAFE® F-Protocol Editor).

Proceed as follows:

  1. Start the Assist CS.. tool.
  2. Select the PROFIsafe F‑protocol and enter the F‑address. The F-address is the unique address of the safe communication node within a PROFIsafe network and is used for checking the authenticity of the connection.

INFORMATION

The following F-parameters are set in the engineering tool of the PROFIsafe controller (TIA Portal):
F_WD_Time – watchdog time that monitors the duration until the next valid PROFIsafe message is received
ParCRCBus (iPar_CRC) – checksum of all safety parameters in hexadecimal format
  1. Parameterize the required safety sub-function.
    • In this example, the SSx safety sub-function is parameterized.
  2. Transfer the data from the Assist CS.. tool to the MOVISUITE® project.
  3. Enter the accepted checksum ParCRCBus (iPar_CRC) of the safety option in the PROFIsafe controller (see F_iPar_CRC).
