168/316 Bosch Rexroth AG | Tightening Technology 7 Data Services7.6 DeviceNet communicationNoteThis setting only reserves the storage space for the logical control signals (1 bit per input or output). Controlsignal assignment is done using the PLC assignment table.Receive dataInterfaceDetermines how many bytes should be reserved to receive the ID code (1 byte per character). The valuerange can be between 0 to 64 bytes.The interface is set as follows on delivery:– MAC ID (Media Access Code Identifier): 63– Baud rate: 125 kbit/sIf desired, you may set another MAC ID and select between 125, 250 or 500 kbit/s or Autodetection forthe data rate.Note MAC ID and data rate are determined during DeviceNet planning. The address section is from 0 to 63.The DeviceNet master (partner controller) is usually assigned the address 0 or 1.⇒After all the parameters have been set, click on Accept to assign the parameters.EDSThe DeviceNet configurator needs a participant profile in the form of an EDS (electronic data sheet) fileto commission the IMdev interface module. The EDS file enables the software to recognize the variableparameters and their value ranges.ExampleIf 16 I was selected as the number of I points and 32 O for the O points, 16 inputs (= 2 bytes) and32 outputs (= 4 bytes) will also be available in the EDS configurator.⇒After setting all the parameters, create the EDS file by clicking on Create EDS file.If a PLC assignment table has been created on the controller, the EDS file will also contain the names ofthe applied control signals. Import the data into the DeviceNet configurator.7.6.2.2 Sending the configuration to the tightening systemThe interface configuration is only valid after the settings have been sent to the tightening system.7.6.3 ID code transfer to the tightening system via DeviceNetThe ID code is transferred by the DeviceNet master to the data buffer of the DeviceNet interface as acharacter sequence (ASCII). An ID code of maximum 64 characters can be transferred per transmissioncycle.The ID code must be stored in the input data area 100 ms before the start of the tightening cycle (startof the tightening channel Ch x.y Cw or Ch x.y Ccw), so that it can be used in the next tightening.The ID code is taken over once the tightening channel has started (CH x.y CW, CH x.y CCW). The tighteningsystem evaluates the stipulated area for the ID code in the data buffer. Irrelevant characters in thestipulated buffer area must be filled up with spaces.System 350 | 3 608 878 040/05.2008
