Overview of commands and samples

The FB EnDat Command object, index 0xB0n8:01 "Request" can be used to trigger various actions such as reading or writing to a specific memory area of the EnDat encoder (depending on the number of channels with n = 0 for channel 1 and n = 1 for channel 2).
The command is entered via the System Manager or the PLC (see following note)

Overview of commands and samples 1:

  • Space between all bytes of the request
    If entered without a space, the command is not accepted correctly.
  • If the command is initiated via the PLC, then this takes place automatically.
