6. Configuring the Gateway
To check that these changes have been entered into the configuration, choose “Monitor” from the “Sub-
Network” menu again:
In point 6), you shall make sure that the total input and ouput sizes of the configured modules
are the same as the exchange sizes displayed in the “Sub-network Monitor.” In the current
example, “In Area 48 bytes” and “Out Area 32 bytes” imply that the modules combined under
SysCon must have a total of 24 IW and 16 OW.
4) Transferring this configuration to the gateway: Please see chapter 6.4 Transferring a Configuration to the
Gateway, page 47. Check that the configuration is valid (LED s G ATEWAY flashing green). However, the
gateway configuration is now different from the one taken into account by the Profibus-DP coupler with
respect to the gateway (difference in the total length of input data), the LED
q F IELDBUS D IAG therefore
becomes flashing red at a frequency of 1 Hz, providing that the gateway is connected to the Profibus-DP
network and to its DPM1 master.
5) Saving this configuration to your PC’s hard disk.
6) Changing the number of data received by the Profibus-DP coupler: Under SyCon, change the list of modules
configured for the gateway (see chapter 4.2.6 Editing and Configuring the Gateway, page 29). Since we have
added 16 bytes after the input data in the gateway memory, the coupler should be configured to receive a
block of input data with 16 bytes more from the gateway.
In this case, all you have to do is add an “INPUT: 16 Byte (8 word)” module after the module configured for
the gateway, as the number of input bytes in the default configuration is even (word-aligned).
