[. . . ] W04E-EN-03 SmartSlice GRT1-Series GRT1-PRT PROFIBUS Communication Unit OPERATION MANUAL SmartSlice GRT1-Series GRT1-PRT PROFIBUS Communication Unit Operation Manual Revised November 27, 2006 ii Notice: OMRON products are manufactured for use by a trained operator and only for the purposes described in this manual. The following conventions are used to classify and explain the precautions in this manual. Always heed the information provided with them. !DANGER !WARNING Indicates information that, if not heeded, is likely to result in serious injury or loss of life. Indicates information that, if not heeded, could possibly result in serious injury or loss of life. [. . . ] To display the most recent error history, click the Update Button. Note The method described is also available in third party FDT Containers, although slightly different terminology may be used in the menus. 41 Setup the GRT1-PRT Configuration Section 3-3 3-3 Setup the GRT1-PRT Configuration Setting up a PROFIBUS Master Unit to exchange parameters and I/O data with the GRT1-PRT and the SmartSlice I/O System involves defining the I/O configuration to the Master Unit and to set parameters needed at run-time. Refer to Appendix A PROFIBUS Technology for more information on PROFIBUS network commissioning. This section discusses the methods of configuration. 3-3-1 Defining the PROFIBUS Network Defining the PROFIBUS network in the Cx-Profibus FDT Container, starts with defining the PROFIBUS Master Unit and assigning the slave devices to it. Defining and assigning devices can be achieved using drag & drop from the Cx-Profibus Device Catalogue. Refer to the CS/CJ-series PROFIBUS DP Master Units Operation Manual (W409) for more information on how to assemble a network. The figure below shows Cx-Profibus with an assembled network in the left window pane and the Device Catalogue opened in the main window pane. To define the I/O Configuration of the GRT1-PRT SmartSlice Communication Unit, double-click the device in the Network view using the left mouse button. A separate configuration window will pop up, which is described in the next section. 42 Setup the GRT1-PRT Configuration Section 3-3 3-3-2 Setup Using the DTM GRT1-PRT DTM window which pops up after double-clicking the GRT1-PRT entry in the Network View is shown below. Note The buttons on the bottom will be enabled only when the DTM is on-line. Parameter Area Tab The Parameter Area Tab, shown above, defines the parameter settings for the GRT1-PRT. · PROFIBUS Settings Box · Extensions Box PROFIBUS Settings Box The PROFIBUS Settings Box contains · the Station address, · the Watchdog Control settings, · the Group Selection · the FINS Fragment length. Station Address Setting The Station Address is automatically assigned by the Master DTM. Only change this setting if the physical device has a different address from the one assigned by the Master DTM. The allowable range is 00 to 99. !Caution It is recommended not to use address 00, since in that case the messaging services will not work. Watchdog Control Setting The Watchdog Control check box allows Enable/Disable of the Communication watchdog. If the Watchdog has been enabled, the GRT1-PRT will revert to a safe state, in case the PROFIBUS communication stops. The Watchdog will be Enabled by default, and it is recommended to leave it Enabled. Note The Watchdog timeout Interval is defined by the PROFIBUS Master DTM and depends on the Bus parameters as well as on the total amount of Slave devices on the network. 43 Setup the GRT1-PRT Configuration Group Setting Section 3-3 The Group Setting selects to which of 8 groups the GRT1-PRT will belong. This setting allows the user to control input and output data on specific groups of devices using the broadcast command. Refer to Appendix A-4 Bus Access Protocol for more information on the broadcast command. The FINS Fragment Length determines the maximum fragment size used on messaging services, when being wrapped in to PROFIBUS messages. The Extensions Box contains a number of settings, which define additional behaviour of the PROFIBUS Master Unit with respect to the GRT1-PRT. This specific behaviour is defined in the PROFIBUS DP extensions standard (PROFIBUS DP-V1), but it does not necessarily require PROFIBUS DP-V1 capabilities from the PROFIBUS Master Units. The Auto-Clear processing box defines whether or not the PROFIBUS Master Unit should ignore a failure of the GRT1-PRT, when Auto-CLEAR has been enabled in the Master Unit (Refer to Appendix A-6 Protection Mechanisms for more information on Auto-CLEAR). When Ignore Auto-CLEAR has been selected, a failure of the GRT1-PRT (i. e. it requests new parameters, or fails to respond) will not activate the Auto-CLEAR mode. This feature can be used in case failure during operation, does not necessitate to switch the entire network to Auto-CLEAR mode. Control Process Auto-CLEAR Description When Auto-CLEAR has been enabled in the PROFIBUS Master Unit, a failure of the GRT1-PRT will cause an Auto-CLEAR event. [. . . ] This bit will - for example - be set if the Unit has more diagnostics available than it can enter in its send buffer. This bit will also be set if the Master Unit receives more diagnostic information than it can enter in its diagnostic buffer. Slave Diagnostics Byte 4: Master PROFIBUS Address This byte contains the PROFIBUS address of the Master Unit, which parameterized the slave. If the slave is not parameterized correctly, the byte contains FF (Hex) or 255 (Decimal). 78 Slave Diagnostics Message Slave Diagnostics Bytes 5 to 6: Ident Number Appendix B Slave Diagnostics Bytes 5 and 6 contain the PROFIBUS Ident Number of the slave device. For the GRT1-PRT PROFIBUS DPV1 slave the Ident number is 098F (Hex). B-2 Extended Diagnostics Module Diagnostics The Module Diagnostics will indicate whether or not SmartSlice I/O Units have communication or configuration errors related to the Unit. 7 Byte 7 Byte 8 Byte 9 Byte 10 Byte 11 Byte 12 Byte 13 Byte 14 Byte 15 Byte 16 7 15 23 31 39 47 55 63 6 14 22 30 38 46 54 62 6 5 4 3 2 1 0 Header byte = 4A (Hex) 5 13 21 29 37 45 53 61 4 12 20 28 36 44 52 60 3 11 19 27 35 43 51 59 2 10 18 26 34 42 50 58 1 9 17 25 33 41 49 57 0 8 16 24 32 40 48 56 64 SmartSlice Slot 1 ~ 7, COM Status (0) SmartSlice Slots 8 ~ 15 SmartSlice Slots 16 ~ 23 SmartSlice Slots 24 ~ 31 SmartSlice Slots 32 ~ 39 SmartSlice Slots 40 ~ 47 SmartSlice Slots 48 ~ 55 SmartSlice Slots 56 ~ 63 SmartSlice Slot 64 Fixed to 0 Module Diagnostics bytes Bit 00 01 64 Name COM Status Module Diagnostics Description When set, this bit indicates that there is Diagnostics information pending related to the COM status.
