The applicomIO Console application has a network diagnostic function
(Diagnostic). The procedure for using the Diagnostic is described below.

“Channel” on the device tree in the left side of the window. The window
changes as shown below.
The CAN and DeviceNet (scanner) tabs appear on the data display in the right
side of the window.
The CAN controller status of the scanner board is displayed on the CAN tab.
Rx : Number of receive data bytes and flames
Tx : Number of send data bytes and flames
OverRun : Number of communication overrun errors detected by CAN
controller
Errors : Number of communication errors detected by CAN controller
Bus Off : Number of Busoff detections
Baud Rate :
baud rate
Bus Load : Load on the bus (maximum, minimum, current)
Use DeviceNet so that the load on a bus is under 60% of the maximum load.
When the load exceeds 60%, the DeviceNet network communication will be
unstable. (For example, more communication errors)
For the procedure for master configuration, refer to respective master device
manuals. For EPSON RC+ master configuration, refer to the section 2.5.5
