Er Data error - out of range
Data send to the display is out of range
Messages
--- No data
The display will show an “---” at node start up, when no data is send to
the display or when the display is disabled.
In Configuration data initialization
The display will show an “In” when the configuration data are
initialized with the factory default values.
Id Wink request received
The display will show a flashing “Id” when the wink request was
received. The node will receive the flashing “Id” will be shown on the
display until the service button will be pressed, or a 30 min delay timer
will expire or a second wink request.
oF Offline
The node is offline: no application is running. This is the result of a
network management command an will happen
- -- --- Controller disabled, waiting for restart
After a major change of the configuration parameter, the rack controller
1 and 2 are disabled for 20 seconds. After this delay the controllers
restart automatically.
The rack controller 1 and 2 are disabled (with object status or with the
network variable nviContEnable[0] and nviContEnable[1]).
