Under normal conditions, the dot LEDs of the wireless master station come on
depending on the registration status of the wireless slave station serial num-
bers, and the wireless slave station displays the node numbers (NNODE). In
the wireless slave station, the right and left dot LEDs come on in the scan list
invalid mode and go off in the scan list valid mode.
Under error conditions, "error code +error occurrence node" are displayed
sequentially, according to the error codes in the order of detection. The error
codes are conform to DeviceNet error codes. In addition, the receiving wave
level is displayed during the test.

This section explains the causes of errors, how to determine their locations,
and the actions to be taken when errors occur in a DeviceNet wireless unit.
Trouble assumable in the system using the DeviceNet wireless can be roughly
classified into the following two cases.
1. Hardware error in each unit
2. Communication error in each network (the upper DeviceNet network be-
tween the DeviceNet master unit and wireless master station, the wireless
network between the wireless master station and a wireless slave station,
the lower DeviceNet network between a wireless slave station and the De-
viceNet slave connected with a wireless slave station)
Hardware errors in each unit can be determined either by the LEDs of the unit
or by the fact that a unit is not added to the upper unit (this could be a wireless
