Interpreting the indicator lights
The indicator lights are used to display the state of operation of the DINRSM. In general, a
green
light indicates correct operation, while a
red
light indicates an error.
Success or failure of an operation
Behaviour:
The
red
or
green
flashes rapidly for about ½ second. A
red
light indicates failure, while a
green
light indicates success.
Event:
⚫
When switching on the device (after a brief delay) to indicate it has started up correctly.
⚫
After a Modbus frame if the response fails (
red
light).
USB connection or radio activity
When a radio message is sent over the network, the
green
light flashes every half-second
while it is being sent. This may last for up to one minute. This light flashes in a similar manner when the
product is connected via USB.
Modbus communication
During Modbus communication, the
green
light remains on throughout the entire process. If a Modbus error
is detected, the
red
light will flash rapidly.
Normal start-up behaviour
When the device is switched on, after a brief delay, the
green
light flashes rapidly for about
½ second to indicate that the device has started up correctly. The periodic frame is then sent out, based on
the statement period specified in the settings. If a USB cable is connected to the DINRSM, the
green
light will
flash as long as that connection is in place.
