LiQuilaz II E and S Operations Manual
Appendix C Modbus TCP Protocol
Modbus Processing Example
The following flowchart provides a basic example of controlling the LiQuilaz II using
Modbus protocol. The flowchart is meant to be a starting point. It does not detail error
handling and does not provide other functionalities which may be desired. The
Optional Processing shown at the start of the flowchart sets the instrument channels.
These may be set by the serial setup interface. The channel settings are non-volatile,
so they only need to be set once when the instrument is first installed and configured.
