4. Software Implementation of the Gateway
4.2.7. Configuring Outputs Intended for the Gateway
On the “Output” tab, select the “LUFP9” gateway, then click on the “AutoMap” button. RsNetWorx then automatically
establishes the correspondence between the 32 data bytes (8-bit format) to be sent to the gateway and the
corresponding 16 PLC outputs “O:1.1” to “O:1.16” (16-bit format).
Please check that a correspondence between all of the data sent to the gateway and the PLC outputs “O:1.1” to
“O:1.16” has been established.
The correspondence between the contents of the gateway’s output memory (see chapter 8.2.2 Output Data
Memory Area, page 85) and PLC outputs “O:1.1” to “O:1.16” is given in the following table:
