Each PLC trigger uses a certain numberof performance points.This enables you to control the extent to which the PLC may be used by the PLCtriggers. The PLC performance index must be defined individually by the machinemanufacturer based on the performance capability of the PLC.Feedback messages to the PLCFig. 3-72: Feedback messages to the PLCFunction DescriptionDB10.DBB118or indiv. dataelementDetermine the S7 data type and S7 format for the data type,with a label for the content of these variables.DB10.DBB119or indiv. dataelementDetermine the S7 data type and S7 format for the data type,with a label for the content of these variables.DB10.DBB120or indiv. dataelementDetermine the S7 data type and S7 format for the data type,with a label for the content of these variables.DB10.DBB121or indiv. dataelementDetermine the S7 data type and S7 format for the data type,with a label for the content of these variables.The S7 data types and formats can be found in the manual "Programming withSTEP 7 V5.4 (in the Appendix "Data and Parameter Types").SINUMERIK Integrate does not support any times and floating point numbers.The S7 data type is also determined by means of the data width. If a word isdefined, the following byte is, therefore, included automatically and blocked for aseparate format. If a double word is specified, all 4 bytes are assigned as doubleword. SINUMERIK Integrate checks the plausibility of the possible formats. Itallows only permissible configurations (the data word 121, for example, is illegal).The checkback signals in an individual DB behave according. However, 8 bytes areavailable. In addition, you must assign identifiers to 4 bytes before and after the 8bytes. These identifiers are evaluated for write privileges.
