Unit Descriptions
DeviceNet Wireless Link
WD30
■ Wireless Interface Specifications
Note: 1. The actual transmission distance depends on many factors in the installation environment.
2. The wireless system is not suitable for applications requiring real-time control.
■ DeviceNet Interface Specifications (Summary)
Note: FINS message communications are not supported. Explicit messages must be handled in the ladder program. Refer to the WD30 DeviceNet
Wireless Units Operation Manual for details.
■ I/O Points
Note: Relay Stations can be used to create up to 3 levels and DeviceNet Slaves can be connected in each level. Terminators are required when
Slaves are connected to a Relay Station or Slave Station. Refer to the WD30 DeviceNet Wireless Units Operation Manual for details on Terminator installation.
