Setting example when you use packet transfer in Siemens SIMATIC Series is shown below.

### Setting of External Device

Use the ladder software of the External Device which will be the PROFIBUS DP Master to register the Display (PROFIBUS DP Slave Unit) as the PROFIBUS DP Master slave and conform the input and output area sizes in the PROFIBUS DP Master to the settings on the Display.

For the packet transfer, you need the interpreter program corresponding to the Siemens SIMATIC Series. The interpreter program is included in the [\Fieldbus\PROFIBUS] folder in the CD-ROM of BLUE. Please refer to "README.TXT" in the same folder for each file description and the setting method.

NOTE

- When using the packet transfer, use OB122 and OB86 in the ladder program of the External Device. When you do not use OB122 and OB86, you need to manually operate the RUN switch of the External Device as "RUN, STOP, RUN" in this order upon restarting the Display. When you use OB122 and OB86, the communication will be automatically recovered even if you restart the Display.
- The input and output area size in the Display must be identical to the settings on the PROFIBUS DP Master.
  When you use packet transfer, the actual input and output sizes will be the values added by 8 words to the each size entered in [Input Size] and [Output Size]. This is because the PROFIBUS DP Slave Unit is recognized as I/O device for the packet transfer and 8 words of the External Device memory must be assigned to both input and output sizes.
