4. Software Implementation of the Gateway
4.2.6. Configuring Inputs from the Gateway
On the “Input” tab, select the “LUFP9” gateway, then click on the “AutoMap” button. RsNetWorx then automatically establishes the correspondence between the 32 data bytes
Please check that a correspondence between all of the data from the gateway and the PLC inputs “I:1.1” to “I:1.16” has been established.
The correspondence between the contents of the gateway’s input memory (see chapter 8.2.1 Input Data Memory Area, page 84) and PLC inputs “I:1.1” to “I:1.16” is given in the following table:
