4. Software Implementation of the Gateway
4.2.9. Configuring the Gateway I/O under PL7 PRO
Using the information located in the selected “.cnf” file, PL7 PRO establishes a direct relation between the data
for each Profibus-DP slave and its equivalent I/O.
To view the LUFP7 gateway I/O, click on the line of the address 2 station in the "PROFIBUS-DP slave
configuration" frame.
If you use the vertical sliders in the "PROFIBUS-DP slave data" frame, you can see that the gateway's 16 input
words have been allocated to inputs %IW4.0 to %IW4.0.15 and that its 16 outputs words have been allocated to
outputs %QW4.0 to %QW4.0.15.
N.B.: these allocations are valid only for the gateway's default configuration and for a gateway which is the only
slave on the Profibus-DP network. If you configure other slaves on the same Profibus-DP network, it may be that
gateway input and output allocation, as it is illustrated above, is amended according to the order in which the
slaves and their modules have been declared under SyCon. Then, you can use the PL7 PRO window, presented
above, to check the allocation of the input and output words of the gateway and other Profibus-DP slaves.
