4.3.11 Machine Data Processing (Modes 20,21,64,67 and 66)
The concept of the IP247 is that machine data records are generated initially using the com-
munications software COM247 at the PG. These data records are then stored as required on the
modes for machine data processing and ensures that the data records are correctly structured
and transferred. Working with the COM247 software is described in detail in Part5"COM247
Communications Software".
Via the PC interface, you can exchange this data between the CPU and I P247 and process it in
the CPU using FBI 65. The procedure is as follows:
generate the machine data records with COM247, transfer them to the I P247, test and op-
timize the machine data
save the data on diskette or hard disk using COM247
if necessary, save the data with FBI 65 in a data block in the CPU
if required, store the data block from the CPU in an EPROM
if required, modify individual data for particular applications in the CPU and transfer the
data record again to the IP247.
Remember that the same machine data record which you fetched from the CPU to diskette with
STEP 5 is not identical to the machine data record which you transfer to diskette using the soft-
ware package COM247.
The modes for machine data processing are as follows:
BA 20 "enter machine data"
BA21 "delete machine data"
BA 64 "read machine data directory"
BA 67 "read machine data"
BA 68 "read machine data overview"
4.3.12

Enter Machine Data (Mode 20)

Using this mode a complete machine data record is transferred via the PG interface or PC inter-
face to the\ P247. COM247 uses mode 20 indirectly if you press the appropriate function key. If
you transfer a machine data record from the CPU to the IP247, you must assign parameters to
FB165 as described in Section 6.2 "Standard Function Block FBI 65".
