Appendix 7 Setting Examples
Connecting with a multidrop link and via network
The following shows setting examples for connecting with a multidrop connection and via network.
■Other stations via network from a multidrop connection
Specify the setting for a multidrop connection including the connected station (host station) and the setting for a connection
via network each.
Specify the station No. of a multidrop connection station for a relay to the station No.
Specify the network No. and station No. of an access target to the network No. and PC No.
The following shows the setting example of the cases below.
• Multidrop connection station of the relay station: Station No.1
• Network module of the access target: Network No.1, station No.2
: Unnecessary
■Multidrop connection station via network
For accessing a multidrop connection station in the target via network, specify the start input/output number of a multidrop
connection source module and the station No. of an access target to the request destination module I/O No. and the request
destination module station No. For the request destination module I/O No., specify the value obtained by dividing the start
input/output number by 16 in 4 digits (hexadecimal).
Specify the network No. and station No. of a network module for a relay station to the network No. and PC No.
The following shows the setting example of the cases below.
• Network module for the relay station: Network No.1, station No.2
• Multidrop connection source module of the relay station: Start input/output number 0050H (request destination module I/O
No.0005H)
• Multidrop connection station of the access target: Station No.1
