Once these tests are successfully completed, the Hand-HeldProgrammer can interact with the PLC.Initially, you must select an operating mode: program mode, protection mode, datamode, or configuration mode. When setting up a new system, you will normally wantto select configuration mode first, in order to configure the I/O modules to be used in thesystem. In configuration mode, you can identify which PLC backplane slots contain I/Omodules, and the size (number of Input or Output points) for each module. Based onthe size of each module, a range of discrete input and output references can either beassigned automatically by the Hand-Held Programmer, or optionally specified by theuser. The configuration of these I/O modules can be changed at any time.After configuring the I/O modules, the next step is to program the actual logicprogram. Program mode is selected for this. Once in program mode, you can create,modify, and monitor the execution of program logic instructions. The optional Series90 Memory Card or EEPROM can be used at any point to save or recall a particularversion of the program.While attempting to debug a logic program, you may need to view and modify data inone or more reference tables. Selecting data mode allows you to accomplish this. Oncein data mode, you can view any of the PLC reference tables in binary, hexadecimal, orsigned decimal format. Only the system register (%R) table can be viewed intimer/counter format.GFK-0402GChapter 1 Introduction to the Hand-Held Programmer1-7
