Select Data Types for Micro Field Processor Data
To configure BIU references for MFP data, use the cursor (F1, F2) keys to go through the avail a ble
MFP data types. On the example screen below, the displayed MFP data type is Q (discrete outputs).
If a data type has not been configured, or if it has been configured with a length of zero, the display
indicates that it is not assigned:
S:7 MFPQ1
< > chg entr
Unassigned
Currently-selected MFP
data type
Note that data from the BIU to the Micro Field Processor's discrete output ( Q ) table will always
start at Q00001 within the Micro Field Processor, as shown on the HHM screen above (MFPQ1).
Similarly, data from the Micro Field Processor discrete input ( I ) table to the BIU will always
come from the MFP starting at I00001 (which is indicated on the HHM as MFPI1).
If you do not want any reference parameters for a Micro Field Processor (if you are using Group
Moves to transfer all dat a bet ween the MFP and the BIU), you must still configure at least on e
reference parameter with a length of zero. The reference parameter configured with the zero length
will show as unassigned.
To assign references to the presently-displayed data type, press the F3 (change) key. the screen
displays:
S:7 MFPQ1 I

in BIU
The upper right corner of the screen shows the BIU table type for the data. On the screen above, it
is the discrete input ( I ) tabl e. Normally, the same data type i s used in both the MFP and the BIU.
Use the F3 (change) key to choose the correct BIU table type.
The HHM then requests a length for that data type. This is the amount of data of the selected type
that will be exchanged with the BIU.
