"The length of the parameter assignment data of slave(8) (DP master system 1)exceeds the maximum length specified in GSD fileSI04801E.GSE." The other 10 I/O modules which is already in use are 8 channel AI modules of the type 6ES7 331-1KF01-0AB0 Kindly direct me to solve this issue. Hello, Please check again that you are using the correct module in the HW config. IM153 which supports up to 12 I/O modules is 6ES7 153-2BA02-0XB0 While 6ES7 153-2AA00-0XB0. In the attachment you will see the both modules in HW config.

Hello MightyITian I fear your problem is caused by GSD file based configuration of the ET 200M (i.e. the ET 200Mwas dragged in from the "Additional Field devices" catalogue). In that case, the244 Byte limit applies to the configuration data (this is a Profibus limit). To fix it you'll need to drag in the appropiateET200M from the "ET 200M" catalogue (so called Metadata configuration which allows exceeding 244 Bytesof configuration data in DPV1 mode with an S7 as the DP Master). You'll need to manually configure it to match the setup ofthe GSD file based one, butyou can have then your 12 modules in it (Note that the problem is not the number of modules, but rather the size of the configuration data with GSD file based configuration). I hope this helps |

Hello MightyITian
The problem is NOT the amount of cyclic I/O data,the problem is the amount of configuration data. This data is only sent once to the DP Slave upon busstartup and must notexceed 244Bytes if GSD file based configurationis done. With a Siemens PLC as the DP Master and metadata based HWconfig of the DP Slave, you can however exceed the 244 Byte limit for configuration data (this abilility is unique to Siemens). The ET200 configurator in the Siemens Industry Mall should tell you the amount of configuration data (I typically do not worry about it though as there is no need with Metadata based configuration).
Your Step 7 V5.4 SP5 version should already have it in the ET200M folder (note that you can also use the "find" field at the top of the HW catalogue to search for it), but you might as welltry a catalogue update as per link below: How do you update the STEP 7 hardware catalog in STEP 7 V5.2 onwards? I hope this helps |
