The Origins of PC Logic Section 1-2 1-1 Overview A PC (Programmable Controller) is basically a CPU (Central Processing Unit) containing a program and connected to input and output (I/O) devices. The pro- gram controls the PC so that when an input signal from an input device turns ON, the appropriate response is made. The response normally involves turning ON an output signal to some sort of output device. The input devices could be photo- electric sensors, pushbuttons on control panels, limit sw

PC Terminology Section 1-3 Actually there is not a total equivalence between these terms. The term condi- tion is only used to describe ladder diagram programs in general and is specifi- cally equivalent to one of a certain set of basic instructions. The terms input and output are not used in programming per se, except in reference to I/O bits that are assigned to input and output signals coming into and leaving the PC. Nor- mally open conditions and normally closed conditions are explained in 4

Overview of PC Operation Section 1-5 1-4 OMRON Product Terminology OMRON products are divided into several functional groups that have generic names. Appendix A Standard Models list products according to these groups. The term Unit is used to refer to all of the OMRON PC products. Although a Unit is any one of the building blocks that goes together to form a C200HX/HG/HE PC, its meaning is generally, but not always, limited in context to refer to the Units that are mounted to a Rack. Most, but n

Peripheral Devices Section 1-6 7. Wire the PC to the controlled system. This step can actually be started as soon as step 3 has been completed. Refer to the C200HX/HG/HE PC Instal- lation Guide and to Operation Manuals and System Manuals for details on individual Units. 8. Test the program in an actual control situation and carry out fine tuning as required. (Section 7 Program Monitoring and Execution and Section 9 Trou- bleshooting) 9.

Available Manuals Section 1-7 PC programs can be written on-screen in ladder-diagram form as well as in mne- monic form. As the program is written, it is displayed on a display, making con- firmation and modification quick and easy. Syntax checks may also be per- formed on the programs before they are downloaded to the PC. The SSS comes on 3.5” disks. A computer running the SSS is connected to the C200HX/HG/HE PC via the Pe- ripheral Port on the CPU Unit using the CQM1-CIF02 or CV500-CIF01 cable
