Modbus Register Types
Product ID (R40,064)
This value identifies the Siemens device type:
Point Data (R41,010 – R41,031)
Measurement point data contain the current instrument readings. These are the values
shown for the reading measurement for each measurement point. The reading is based
on the setting for P001 (operation). P001 can be set to level, distance, OCM flow, or
volume. See
Parameter Reference
section on page 117 for details.
The measurement registers are 41,010 to 41,012. The MultiRanger uses 41,010 when
configured with a single transducer and 41,010 to 41,012 when configured with two
transducers (P111=4 or 5 only). Two transducers can create three readings because they
can generate an average or differential reading (R41,012) as well as the two level
readings (R41,010 and R41,011).
Available registers:
The reading is expressed as a percentage of full scale, multiplied by 100:
Totalizer (R41,040 – R41,043)
The totalizers are stored as 32 bit integers using two registers. The totalizers can be read
with R41,040 and R41,041 as totalizer for Point 1, and R41,042 and R41,043 as totalizer for
Point 2. The totalizer values can be reset to any value by writing that value to the
registers. The values can be cleared by writing zero (0) to the registers.
Input/Output (R41,070 – R41,143)
The MultiRanger has discrete inputs, mA inputs, mA outputs and relay outputs. See
below for details for each I/O type.
