4.6.8 Modbus Output Setup Registers

Configuration of the IO-FEP2 outputs starts at register 03001. The setup data for each output covers 20 registers, meaning that the setup configuration for output 2 starts at 03021, for output 3 at 03041 and so on. Setup of output 32 starts at address 03621 and ends with and including 03637.

The register definitions for output 1 are:

Remarks:

1. Output type 2 (temperature control loop output) only can be set if temperature control loops are licensed. Without license, the output type will fall back to 0 (not used) when configured to this state.
2. Output type 4 (hardware controlled WG switch muting output) cannot be set explicitly. This state is detected from the IO-FEP2 hardware, if the DIP switch for an output is set to (hardware controlled WG switch muting, this register becomes read-only and always reports 4
