YASKAWA TOEP YEACOM 06A V1000 Option PROFINET SI-EP3/V Installation Manual 418 Network Topology and Connections8 Network Topology and ConnectionsThe dual RJ45 network ports on the option board act as a switch to allow for flexibility incabling topology. For example, a traditional star network topology (Cable Topology A), maybe employed by using a single port on the option board. Alternatively, a daisy-chainedapproach may be employed by using both RJ45 ports. The daisy chain approach (CableTopology B), reduces the requirements of central switch ports. Refer to Figure 39.Use the second communications cable port to daisy chain a series of drives where applicable(Cable Topology B). Refer to Figure 39.Figure 39Figure 39 Topology Options◆ Communication Cable Wiring■ Communication Cable SpecificationsOnly use cables recommended for PROFINET. Using a cable not specifically recommendedmay cause the option or drive to malfunction.The use of CAT5e or equivalent Shielded Twisted Pair (STP) cable is recommended.STOP(Hz)(Hz)(A)(V)V1000STOP(Hz)(Hz)(A)(V)V1000STOP(Hz)(Hz)(A)(V)V1000STOP(Hz)(Hz)(A)(V)V1000STOP(Hz)(Hz)(A)(V)V1000STOP(Hz)(Hz)(A)(V)V1000Traditional Star Network Daisy Chain NetworkCable Topology A Cable Topology B
