Dear all, As per Siemens technical sheet (As link mentioned below) the IM can handle 244 byte of Input Data. http://support.automation.siemens.com/WW/view/en/20132586/td But unfortunately we are unable to insert more than 68 byte. The message coming "The maximum length of the configuration data for a slave with the PROFIBUS address 4 has been exceeded." Can any one guide. Regards, ddg |

the configuration data is to large you are going to have to split the node up to get your configuration telegram down in size |

Hi, i think you got the right answer already! "the configuration data is to large you are going to have to split the node up to get your configuration telegram down in size" Maybe meaning of that answer isnot clear. There are two different things: Maximum Data length for cyclic data --> these are really your analog values --> 244Bytes (not reached till now). BUT: You are using Analog modules. This module must be configured by the Master. Measurement range, diagnostic etc. For Analog modules the amount of data is also more than simple digital modules. AndPlayerslight said maybe this data reaches the maximum length of this configuration telegram (will be sent only once time during startup of the station). I thinkalso that this can be the reason and the error message of Step7 is not 100% correct. To verify this you can use the SIMATIC Selection tool (www.siemens.de/simatic-selection-tool). Put your configuration and let the tool check the data size. This tool will calculate also the configuration data. If you get also the result, that the configuration isn't possible, then you must use 2x ET200S. |
