Section 1 gives a brief overview of the history of Programmable Controllers and explains terms common-
ly used in ladder-diagram programming. It provides an overview of the process of programming and oper-
ating a PC and explains basic terminology used with OMRON PCs. It also describes the Programming
Devices that can be used and provides a list of related FA products and manuals.
Section 2 provides information on hardware aspects of CVM1D PCs that are relevant to programming
and software operation. These include switches on the CPU Unit and basic PC configuration. This in-
formation is covered in more detail in the CVM1D Installation Guide.
Section 3 describes the way in which PC memory is broken into various areas used for different pur-
poses. The contents of each area and addressing conventions, including the use of indirect addressing
and addressing registers, are also described.
Section 4 explains the basic steps and concepts involved in writing a basic ladder diagram program. It
introduces the instructions that are used to build the basic structure of the ladder diagram and control its
execution, along with a few other instructions of special interest in programming.
Section 5 explains each instruction in the CVM1D PC instruction set and provides the ladder diagram
symbols, data areas, and flags used with each.
Section 6 explains the execution cycle of the PC and shows how to calculate the cycle time and I/O re-
sponse times. I/O response times in Link Systems are described in the individual System Manuals.
Section 7 lists the parameters in the PC Setup, provide examples of normal application, and provide the
default values. The use of each parameter in the PC Setup is described where relevant in this manual and
in other CVM1D manuals.
