WARNING!
MODBUS MASTER SHALL NOT WRITE INTO ANY REGISTER THAT IS NOT INCLUDED IN THE ABOVE TABLE!
* Note: DynaFLO
’s PLC’s Registers are 0-based thereby for e.g. MI0 = Modbus 40001 (Unless the Modbus software also uses
its own offset in which case the specific software has to be consulted.)
** Note: These commands are for reference only as each Modbus software has a different interface with different options and
ways of converting commands.
5.2
– Screen Navigation
The chart below shows the controller’s menu structure.
The start-up screen lists three options, <Control>, <Setup>
and <Alarm>. Each option is explained in the next section. On
the top right there is a display that indicates that status of
alarms.
The controller uses a two-tiered password protection scheme.
The low level password is needed to access the Setup menu.
The higher level password is needed for configuring the P, I
and D parameters as these parameters are no recommended
to be changed.
