DA501

• The DA501 module only reports analogue IOs even though it has also binary inputs / outputs.

• It uses the following IO data structure:

  Inputs:

  • Digital Inputs (channel 0..15) (16bits, 2 bytes)

  • Analogue Input 0 (2 bytes)

  • Analogue Input 1 (2 bytes)

  • Analogue Input 2 (2 bytes)

  • Analogue Input 3 (2 bytes)

  • Binary Inputs (channel 16..23) / reserved (16bits, 2 bytes)

    bits 0..7 binary inputs

    bits 8..15 reserved

    Outputs:

  • Analogue Output 0 (2 bytes)

  • Analogue Output 1 (2 bytes)

  • Reserved (2 bytes)

  • Binary Outputs (channel 0..7) / reserved (16bits, 2 bytes)

    bits 0..7 binary outputs

    bits 8..15 reserved
