GFK-0825F Chapter 5 Station Configuration 5-101
5
Enter the data length from the keypad, then press F4 (enter) to save it. The HHM displays the offset
(reference address) of the first reference of the selected type that is available in the BIU. For
example, if Q00001 through Q00032 were already assigned to other modules, the next available
reference would be Q00033:
S:7 MFPQ1 Q:016
< > chg entr
Ref Addr 00033
If you enter an invalid length value or overlapping references, the HHM displays an error message.
If that happens, press the HHM Clear key and make a new entry.
If you enter a number that is not on a byte boundary for discrete data, the BIU will round down to
the nearest correct offset.
Select other MFP data types and specify BIU data types and references.
Assign Data Defaults
Next, set the default for each configured type of BIU data (unassigned data types are not displayed
here).
For the input data types AI and I, select what the BIU should do with the MFP's data if the BIU
loses communications with the MFP. Data can either be held at its present values or defaulted to
zero.
S:4 Module-> %I
DEFAULT:ZERO
< > tgl entr
S:4 Module-> %AI
DEFAULT:ZERO
< > tgl entr
You can accept DEFAULT: ZERO with the F4 (enter) key, or press F3 (toggle) then F4 (enter) to
change to DEFAULT: HOLD and save it.
For output (Q and AQ) data which is included within the BIU's I/O map, determine what data the
BIU will send to the module if the BIU loses communications with the network.
S:4 Network-> %Q
DEFAULT:ZERO
< > tgl entr
S:4 Network->%AQ
DEFAULT:ZERO
< > tgl entr
When you are finished assigning and saving the Reference Parameters and data defaults for the
Micro Field Processor, use the F2 ( > ) to return to the first Micro Field Processor configuration
screen.
