Diagnostics
Overview
The LEDs installed to display the status allow extensive diagnostics during the PowerON-procedure as well as during operation. The result of the diagnosis is determined by the combination of the different LEDs and the current operating mode.

The following operating modes are available depending on the position of the address selector:
•
DeviceNet mode (address selector in position 0 ... 63)
•
Configuration mode (address selector in position 90 ... 92)

LED Description
PW on
ER off
After PowerON the PW-LED is turned on and indicates a properly operating power supply. The RD-
RD blinks LED blinks since the configuration data, stored in the
BA off EEPROM, was transferred successfully into the
PW on peripheral modules.
After PowerON the PW-LED is turned on. The ER-
ER on
RD off
BA off
LED is on due to errors on the backplane bus or when the configuration data could not be transferred into the peripheral modules.

ER off The RD-LED blinks because:
RD blinks
• the backplane bus is operating properly
BA blinks
• the configuration data was transferred successfully
from the EEPROM into the configurable peripheral modules.
PW on
The BA-LED blinks because:
• at least one additional device is active on the
DeviceNet,
• and the address set up on the coupler is unique.
After PowerON the PW-LED is turned on. The ER-
ER on LED is on due to one of the following conditions on the

• bad address or address occupied by another device
• data transfer rate is bad.
After PowerON the PW-LED is on.
The ER-LED is turned on when the configuration data
RD blinks could not be transferred into the configurable
BA blinks peripheral module.
The RD-LED blinks because
• the backplane bus is operating properly
• the configuration data was not transferred into the configurable peripheral modules.
The BA-LED blinks because
• at least one other device is active on the DeviceNet,
• the address set up on the coupler is unique.

PowerON with
DeviceNet and master
LED Description
PW on
ER on
After PowerON the PW-LED is on.
The ER-LED is turned on since the configuration data
RD blinks was not transferred into the configurable peripheral
BA on modules.
The RD-LED blinks because
• the backplane bus operates properly
• the configuration data was not transferred into the configurable peripheral modules.
The BA-LED is turned on
• because the coupler IM 253DN has established a
DeviceNet-connection to a master.
Note!
The IM 253DN coupler executes a reset after 30s.
An error that occurs during PowerON with DeviceNet and master displays the same combination of LEDs as a hardware error.
It is possible to distinguish between these cases:
• by interruption of the DeviceNet connection
→
ER-LED and RD are blinking!
• with a network WHO in the DeviceNet-Manager
→
in case of a hardware error the IM253DN
will not appear on the network.
Note!
Please call the VIPA hotline if a hardware error occurs!

Description
After PowerON the PW-LED is on. The RD-LED is turned on because the connection to the peripheral modules could be established via the backplane bus.
The BA-LED is turned on because the coupler

The ER-LED is turned on for 1 second because a module error was detected. Subsequently the coupler
IM 253DN will execute a reset. After the reset the coupler is re-started and it indicates the error by means of the respective LED combination.

RD blinks because the I/O-connection does not exist any
BA on longer. All inputs and outputs are set to zero.
The BA-LED is turned on because the connection with the master is still established.

After PowerON the PW-LED is turned on and indicates that the power supply operates properly.
The RD-LED is turned on after a short delay since the baudrate was transferred into the EEPROM.

The address that was set up on the coupler is not valid.
Change the address to a valid setting:
•
0 ... 63 as DeviceNet address
•
90 ... 92 for the definition of the baudrate
When the coupler is not connected to the DeviceNet, an error was detected in the internal EEPROM or in

RAM. When a DeviceNet connection exists, it is also possible that an error has occurred during the transfer of the configuration data into the peripheral modules.
Note!
Errors that occur during PowerON with DeviceNet and master display the same combination of LEDs as a hardware error.
It is possible to distinguish between these cases:
• by interruption of the DeviceNet connection

• with a network WHO in the DeviceNet-Manager
→
in case of a hardware error the IM 253DN
will not appear on the network.
