Unit model
The data provided by the LMIT09 DPV1 is split into the blocks described below within the
unit using its own logic.
The blocks and parameters described can be access through mapping.
The acyclical access address is determined as described below.
n Slot: Refer to the table for the slot number of the required block.
n Index: The index of a parameter is determined from the start index for the block plus
the relative index of the parameter.
Block
Unit block
Temperature block
Conductivity block
Concentration block
Code block
Product block
The cyclical parameters are transferred to the PLC in the DataExchange input
datastream in accordance with the following table:
Octet 1-4
Temperatur
e
The following additional information is transferred from the PLC to the unit in the
output datastream.
Octet
For details of the coding for the parameters, refer to the descriptions of the associated
blocks.
