Meaning Meaning
Incorrect or no connect telegram and
startup data sets transferred to
interface module -- there is no data
exchange between the I/O controller
and the interface module (I/O device).
Causes:
•
Device name is incorrect
•
Configuration error
•
Parameter assignment error
No I/O controller on bus
Causes:
•
No bus communication
The configured setup of the ET 200S
does not match the actual setup of the
ET 200S.
There is an error in an I/O module, or
the interface module is defective.
Incoming diagnosis
•
An MMC is not inserted.
•
The inserted MMC is full or does
not have enough memory for the
device names.
•
No suitable MMC is inserted (i.e.
no MMC from Siemens).
Data transfer is taking place between
the I/O controller and the ET 200S.
The target configuration and actual
configuration of the ET 200S match.
Remedy Remedy
•
Check the interface module.
•
Check the configuration data and
parameters.
•
Check the device name.
•
Establish a connection to the
I/O controller (via a switch).
•
Assign a valid device name to the
interface module.
•
Check the bus configuration.
•
Check that the bus connector is
correctly inserted.
•
Check if the interconnecting cable
to the I/O controller has been
interrupted.
Check the setup of the ET 200S,
whether a module is missing or
defective, or whether an unconfigured
module is inserted.
Check the configuration (using
STEP 7, for example), and correct the
parameter assignment error.
Replace the interface module, or
get in touch with your Siemens
contact person.
Before power on insert an empty MMC
into the IM151-3 PN.
