Parameter Access (R43,998 – R46,999)
Parameter values are given as integers in the range of registers from R44,000 to R44,999.
The last three numbers of the register correspond to the parameter number.
Parameter Register #
44,000
44,001
44,002
...
44,999
Usually, the parameters are all read / write.
Note:
• Parameters P000 and P999 are read only. If P000 is set to lock activated then
all of the parameters are read only via the handheld programmer
• Parameter P999 (Master Reset) cannot be used via Modbus

associated with different parameters
Each parameter register has a corresponding format register that holds the format
information required to interpret the value. See
page 103.

Parameter Indexing

Many parameters are indexed. There are two possible indexes: a primary index and a
secondary index. A secondary index is a sub-address of the primary index. Some indexed
parameters affect multiple I/O devices.
The following is an example of a primary index:
P111 is the Relay Control Function. This parameter determines how a relay is controlled
by the HydroRanger 200 (used as an alarm, for pump control, etc.). Because there are up
to six relays on the HydroRanger 200, P111 is indexed by six to allow each relay to be
programmed independently.
A few parameters also have a secondary index. While a secondary index is important for
setting up the HydroRanger 200, it is almost never needed through remote
communications.

Indexing the Parameter Access Area

Each parameter communicates its value to only one register. You must know the index(es)
for the parameter in order to interpret the information in the register correctly.
For example, to make use of the value returned in register R44,111 you must know which
relay it is referring to. See
P111 values.
