■When accessing from an Ethernet interface module
When accessing a multidrop connection station with the frames (4E frame, 3E frame) for the Ethernet interface module,
specify the start input/output number of a multidrop connection source module (relay station) and the station No. of an access
target to the request destination I/O No. and the request destination module station No. For the request destination I/O No.,
specify the value obtained by dividing the start input/output number by 16 in 4 digits (hexadecimal).
The following shows the setting example of the cases below.
• 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
: Unnecessary
Accessing via network
When accessing other stations via network, specify the network No. and station No. of an access target network module to the
network No. and PC No.
The following shows setting examples for accessing other stations via network (network No. 1, station No.2) without a
multidrop connection.
