Modbus register definitions are listed below for each type – DINCon, DINPres, and
DINTemp.
For floating point values the DIN modules use the standard IEEE-754 format.
The Modbus address and communication parameters for a module can be changed by
writing to registers 104-109 as a block (at the same time).
The Modules contain a Real Time Clock that will be set to the current date and the end
users time zone prior to shipment from Parker. If re-setting the Real Time Clock is
needed, the data must also be written in one continuous Modbus multi-register write
operation to registers 130-137.
The DINPres Module has a selectable Data Refresh Rate, with the default of 13
milliseconds being raw data. (Register 143) If the default setting is not used, a
conditioned signal is provided.
The Sensors have individual ID numbers and calibration information stored in, and
printed on them. Values relating to the ID numbers can be found in registers 201-206
for Sensor 1, 241-246 for Sensor 2 and 281-286 for Sensor 3. (Note: The first letter of
this ID number, a “C”, “S” or “T”, is not in any of the registers.)
Units and Alarm Limits:
The Modules provide the ability to set the desired Units for the outputs, as well as
appropriate High and Low Alarm Limits. The alarms are absolute and not dependent
upon signal direction. (i.e. The signal does not have to be above the low alarm limit
value first to trip it.) The register list in section C below lists the available units for each
Module. All Alarm Limits default to 0.0 and are thereby initially disabled.
