KEY POINTS
•
Scan List is a list for setting the connection information with "Target". Use
Programming software FPWIN GR7 for the registration.
• For registering other companies' EtherNet/IP devices in Scan List, the EDS
files of those devices are required. Communication parameters that can be
set in each device are defined in the EDS files.
