Cause
No supply voltage available on COMPACT
module.
Hardware defect on COMPACT module.
Supply voltage available on COMPACT
module.
The COMPACT module is not configured or is
configured incorrectly. No data exchange is
taking place between the DP master and the
COMPACT module.
Causes:
The PROFIBUS address is incorrect.
•
Configuration error
•
Parameter assignment error
•
Transmission rate detection, illegal
PROFIBUS address, or lowermost DIP switch
(PROFIBUS address) not in the OFF position.
Causes:
The response monitoring has elapsed.
•
Bus communication with the COMPACT
•
module via PROFIBUS DP has been
interrupted.
The designed configuration for the IM151-1
COMPACT (ET 200S) does not match the
actual configuration of the station.
There is an error in an I/O module, or the
COMPACT module is defective.
Parameter assignment incorrect
•
Hardware defect in the COMPACT
•
module's integrated I/O.
Short circuit in the sensor supply of the
•
digital inputs or in the load voltage for the
digital outputs.
Action
Switch on the power supply voltage 24 VDC
on the COMPACT module.
---
Check the COMPACT module.
•
Check the configuration and parameter
•
assignment.
Check the PROFIBUS address.
•
Set a valid PROFIBUS address (1 to 125) at
the COMPACT module, or check the bus
configuration.
Check that the bus connector is correctly
•
inserted.
Check whether the bus cable to the DP
•
master has been disconnected.
Switch the 24 VDC supply voltage off and
•
on again at the COMPACT module.
Check the configuration of the ET 200S to
determine whether a module is missing or
defective or whether an unconfigured module
is inserted.
Check the configuration (e. g., using COM
PROFIBUS or STEP 7), and correct the
parameter assignment error.
Replace the COMPACT module, or contact
your Siemens representative.
Check the parameter assignment.
•
Exchange the COMPACT module.
•
Check the supply lines.
