6. Configuring the Gateway
In this case, all you have to do is add an “INPUT: 4 Byte (2 word)” module after the module configured for the gateway, as the number of input bytes in the default configuration is even (word-aligned).
Under SyCon, all the configured modules start from an even address (word-aligned). When you change a configuration that includes a one-byte module, you must remove it (“Remove module” button or double-click on the module in the list of configured modules, see page 65) before adding “IN/OUT”, “INPUT” and “OUTPUT” modules to the list of configured modules. This type of module should therefore only be at the end of the list.
N.B. Removing the 2 output bytes located at addresses 16#0208 and 16#0209 in the gateway memory has no impact on the overall size of the input data transmitted to the Profibus-DP coupler. These bytes become "Free memory locations", like the byte at address 16#0012.
In this example, the modules configured for the gateway are listed on the right.
Then you should save and export the configuration of the Profibus-DP network, as described in chapter 4.2.7 Saving and Exporting the Profibus-DP Network Configuration, page 31.
7)Configuring the Profibus-DP master PLC outputs: under PL7 PRO, import the new configuration of the Profibus-DP network (see chapter 4.2.8 Importing the Configuration of the Profibus-DP Network under PL7 PRO and following chapters, from page 31). Words %QW4.0.16 and %QW4.0.17 are now displayed in the "PROFIBUS-DP slave data” frame of the TSX PBY 100 coupler configuration window, providing that the address 2 station is selected in the list of the “PROFIBUS-DP slave configuration” frame.
We get the correspondence represented on the next page, derived from the one used for the gateway default configuration. The changes in relation to the default configuration are shown by a greyed-out background, like the “free memory locations”.
