About Jochen_Mueller

Hello Maurus We need to reduce the possible error situations. The error can occur at The actual position provided by the PLC Please read the value from the web-interface or over REST (is it 74,6??) the value read by the C++ App please check the value in debug mode of the c++ App alternative write the value to a customer node at the datalayer and check the value the value written in the logbook if the value is correct at the upper points, it seems that either the writting in the logbook is not correct or the logbook display the value not correct   Please check the different points.

  Some extented explantation: The FB DL_ReadNode can be used to read every values from the datalayer, independent to the type. Link to docu of DL_ReadNode (Here you find the description and an example.)   But the variable you connet at "Value" must fit the datalyer type. Means you have to check the type of the datalayer-node and depending on this declaring the PLC-variable. Here you see it's a "number" (float). if you don't see it clearly 🙂 additional you have the possibility to check it at the DataLayer tree under "types". (I know it's not nice to read.) Schema of the lim: { "$schema": "http://json-schema.org/draft-04/schema#", "definitions": { "motion_core_fbtypes_AxsCfgLimits" : { "type" : "object", "properties" : { "posMin" : { "type" : "number" }, "posMax" : { "type" : "number" }, "velPos" : { "type" : "number" }, "velNeg" : { "type" : "number" }, "acc" : { "type" : "number" }, "dec" : { "type" : "number" }, "jrkAcc" : { "type" : "number" }, "jrkDec" : { "type" : "number" } }, "additionalProperties" : false } }, "$ref" : "#/definitions/motion_core_fbtypes_AxsCfgLimits"}   Hope this helps. ...
