∗ 1. The cable length restriction in repeater (repeater hub or switching hub) usage varies depending on a selected
baud rate.
For repeater or switching hubs, use a commercially available hub for Ethernet. Hubs manufactured by the Japan
Electrical Manufacturer’s Association (JEMA) are recommended.
• Restrictions on 100BASE-TX connection
• Restrictions on 10BASE-T connection
∗ 2. The I/O assignment restriction, which defines that the maximum number of nodes as 64 nodes including the self-
node, is based on MP Series Machine Controller specifications.
∗ 3. A message can be only sent from the client. (Client: Data sending side, Server: Data receiving side)
