APPENDIX B

MODBUS REFERENCE

This appendix describes the Modbus protocol implementation of the

HMW90 series digital transmitters.

NOTE

For more information on Modbus protocol, refer to the Specification and

Implementation Guide for Modbus Over Serial Line.

NOTE

Serial line settings such as baud rate are configured using DIP switches.

See section Configuration of Digital Output Models on page 23.
