Dear PLCnext community, I am currently trying to connect a Siemens ET200 SP I/O module to my AXC 2152 PLC. Previously a Siemens controller was used with this profinet module with a certain IP adress.
With the GDSML file of the module i have set up the profinet device with all modules in PLCNext engineer, but i can not connect to it.
In the web manager of the PLC the following code is given:
Diagnostics Status: Code 0x0023
Bit 0: Lost connection to Device
Bit 1: Invalid Data
Bit 5: Neighborhood information is not available It seems the connection is not possible or never established, is there possibly anything missing? Kind regards, Coen EDIT:
After editing the DNS device name, i am now able to connect. Yet i still get these error codes: Diagnostics Status: Code 0x040c
Bit 2: Diagnosis is available
Bit 3: Module difference is available in case of configuration difference
Bit 10: Channel or manufacturer specific Diagnostic information is available What do these error codes mean?
Hi Coen, the important flag is “Bit 3: Module difference is available in case of configuration difference” and that means that there is a mismatch between what you’ve configured in your application and what is really installed.
Depending on the behavior of the device and kind of the mismatch (e.g. just an additional module at the end) were the process data still valid, which seems to be here the case. Now coming to the question were did the ET200 detect the mismatch ?. As I’m not that familiar with the ET200 I’ll come back to the general procedure:
1. If the device does have a WBM it should be very easy to find the issue.
Just open it and check the log for any issues or alamrs.
2. In case the device does not have WBM you can receive and check the Alarm message (coming from the device) with the RECV_ALARM functionblock in PLCnext Engineer
3. Or check the manual of the device if there are some LED information which leads you to the right way
The best would of course to use one of our IO BKs (like AXL F BK PN TPS - 2403869 or IL PN BK-PAC - 2403696) which all have a build in WBM for an easy diagnostic. Hope that helps, Frank
