Chapter 6 Symbols Press Alt+ on the keyboard twice. Press Alt+ on the keyboard once. Besides, if users click the heading Identifier or Address in the global symbol table in a project or the local symbol table in a POU of the program type, the data in the table will be sorted according to the contents of the Identifier column or the Address column, and a mark indicating the sort direction will appear in at the right side of the heading Identifier or Address. Owing to the fact that the order in which the symbols in the local symbol table in a function block are arranged affects the order in which the operands in the function block are arranged, the data in the local symbol table in a function block can not be sorted in this way. 6.2.10 Filtering the Symbols Users can view the symbols which meet the same conditions. (1) Right-click a symbol table, and click Symbols Filter on the context menu. 6-21
ISPSoft User Manual (2) Users can set the conditions in the Symbols Filter window. The wildcard character “*” can be used to substitute for any character or characters in a string. The symbols which satisfy the conditions set are sieved out. If the users want to ignore a certain condition, they can leave the box for the condition blank. Click OK after the setting is complete. (3) The symbols which are sieved out are displayed in the additional page. The users can switch between the pages by clicking the tabs at the top of the table. If several groups of symbols are sieved out, the users can switch among the tabs by clicking or in the upper right corner of the window. If users click in the upper right corner of a page, the page will be closed. Besides, these additional pages are for view only. Users can not edit the tables in the pages. After the users click the Normal tab, they can edit the original symbol table. 6.2.11 Setting a Range of Devices (Only for DVP Series PLCs) The devices automatically assigned to the symbols in a project for a DVP series PLC are devices available to users. Users set a range of devices which can be automatically assigned to the symbols in a project so that they can manage the devices conveniently. They can set a range of devices for a project created. When the program in a project is compiled, devices within the range which is set are assigned to the symbols. If the number of symbols is larger than the devices within the range, an error message showing that the devices are insufficient will appear after the program in a project is compiled. Please refer to section 6.1.4 for more information about assigning devices to the symbols in a project. Unfold the PLC section in the project management area in a project for a DVP series PLC, double-click Device Resource Allocation. 6-22
