A network must be activated via the configuration for every CPU program. Since
there is no separate order number for the HHU CPU programs, the standard
order number of the AS314 must be used. MPI address 2 is networked for the
AS314 CPU program and MPI address 15 for the HHU program. “0” must al-
ways be entered as the MPI SUB network number.
“Networking” sequence for each CPU program:
1. Set “Module networked”.
2. Set MPI address and enter SUB network no. 0.
3. Confirm with “OK”.
4. Save the configuration with “Save”.
Start the Communication Configuration tool and set up a new file.“table 1” ap-
pears.
You now need to call the CPU programs in table 1.
1. Using the mouse, click on the field next to GD identifiers (the column is then
color-highlighted).
2. Click “Select CPU module” under menu item “PLC functions”.
3. A window headed “Select CPU” appears. Click on project Example and the
2 CPU programs are displayed: as314, bhg.
4. Select as314.
5. Table 1 appears with entry as314//CPU1::
6. Click on empty field to the right of it and repeat steps 2 to 5 above in the
order given for CPU program bhg.
7. The result will be Table 1 containing the 2 CPU programs.
