Remarks
With a configuration of two or more networks, be sure that the Machine Controller that per-
forms network relaying is linked to only one station in each network.
In the example given above, the following five stations conform to this requirement.
• NW#1: ST#1
• NW#2: ST#10 and ST#12
• NW#3: ST#20
• NW#4: ST#30
A Machine Controller that performs network relaying is an MP920 Machine Controller with two or
more 215IF Modules with ports connected to different networks to transfer data between the networks.
