[. . . ] W05E-EN-01 WS02-9094G CX-PROFIBUS Ver. 1. 0 OPERATION MANUAL SYSMAC WS02-9094G CX-PROFIBUS Ver. 1. 0 Operation Manual Produced July 5, 2005 iv 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. [. . . ] In order to change the parameter setting, double-click the row, with the left mouse button. Depending on the type of parameter and the selection options, either the field can be edited directly, or a drop-down list with options will appear. Note The parameter settings must be performed carefully. In general, the slave device will reject the parameter message, if it contains any faulty parameter. Consequently, the slave device will not reach I/O data exchange with the PROFIBUS Master. The parameter values are by default displayed in Hexadecimal format. By checking the check box at the bottom, the values are converted to decimal values. Module Parameters Group Tab In the Group tab the user can define to which group the slave device will belong. This group definition is used to define multi-cast groups of slave 60 Generic Slave Device DTM Section 2-5 device to which a Global-Control message can be transmitted. The window is shown below. Selecting the Groups The user can check the check boxes for each group the slave device will belong to. The group setting is transferred to the slave device as part of the parameter message. The three tabs discussed above, allow for making all the standard PROFIBUS DP settings for a slave device. For slave devices supporting PROFIBUS DPV1, two additional tabs will show up. These tabs will appear, if the GSD file parameter GSD_Revision is set to 3 or higher. The additional tabs are discussed below. Extensions Tab The Extensions tab contains a number of settings, which define additional behaviour of the CS1/CJ1W-PRM21 PROFIBUS Master Unit with respect to a particular PROFIBUS DP-V1 slave device. Although this specific behaviour is defined in the PROFIBUS DP extensions standard (PROFIBUS DP-V1) it does not necessarily require PROFIBUS DP-V1 capabilities from the PROFIBUS Master Units. The Extension tab is shown below. 61 Generic Slave Device DTM Section 2-5 Auto-Clear Processing The Auto-Clear processing box defines whether or not the PROFIBUS Master Unit should ignore a failure of this particular slave, when Auto-CLEAR has been enabled in the Master Unit (See Auto-CLEAR Box on page 32 in section 2-3-1 Configuration User Interface). When Ignore Auto-CLEAR has been selected, a failure of this particular slave device (i. e. the slave device requests new parameters, or fails to respond) will not activate the Auto-CLEAR mode. The Master Unit will however, service the slave device. This feature can be used with slaves which can fail during operation, but for which failure it is not necessary 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 this particular slave will cause an Auto-CLEAR event. When Auto-CLEAR has been enabled in the PROFIBUS Master Unit, a failure of this particular slave will not cause an Auto-CLEAR event. The Master will however service the slave device (e. g. send new parameters). Ignore Auto-CLEAR Configuration Data Convention The Configuration Data Convention setting defines how the slave device will handle the special identifier format data parts of the Check I/O configuration message. [. . . ] · Make sure the Personal Computer COM port selected within the Device Set-up Configuration is not in use by another application. If it is close the connection from within the other application. · Restart Personal Computer to ensure COM port is released. · Ensure the correct version of CXServer is installed on the Personal Computer.
