Program Mode Interface – Entering Program Mode via Modbus
Entry to Program mode via Modbus is done by simply writing a value to a configuration
register in the map (assuming all security requirements are met). Each write to the con-
figuration restarts the auto-logout timer. If three seconds transpire with no additional
updates (writes), it is assumed by the microFlow.net Liquid that the host has completed
the Program Mode session and the changes will be accepted and used (if all were valid).
See the Operator Reference manual for detailed descriptions of the various Program
Codes available for configuration of the microFlow.net Liquid.
2.24
Program Mode Interface – Explicit Logout Command
Register: 40577 (Function 6/16 – Write Holding Register) – word data
If it is not desired to wait for the three second period to expire, it is possible to force
the unit to exit program mode immediately by writing to the above register. If the value
1 is written, the preceding changes will be accepted and used. If the value 2 is written,
any changes made will be abandoned and the original values prior to entry into Program
mode by the Modbus host will continue to be used.
Note:
this immediate logout functionality is also assumed implicitly when host commands like Allocate Recipes
or Set Batch are issued when in Program mode via Modbus.
