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)


Item Specifications
Communications functions (See note.) Master/Slave connections Remote I/O functions and Explicit message communications functions
Self-diagnostic functions Unit WDT error, hardware errors (such as memory and CAN errors), and setting errors
DeviceNet communications Duplicate node address errors, Bus OFF detection, and connection timeout
Device profiles Communication control unit Refer to Appendix A of the WD30 DeviceNet Wireless Units Operation Manual for various DeviceNet IDs (vendor, device type = communication adapter, product code, product revision, product name, serial number, status, and I/O unit IDs.)

Note: FINS message communications are not supported. Explicit messages must be handled in the ladder program.



I/O Points


Name Number of I/O points (words used)
DeviceNet Wireless Master 1,600 inputs max. (100 words)
1,600 outputs max. (100 words)
