3-10 Program Memory
Program Memory is where the user program is stored. The amount of Pro-
gram Memory available is either 4K or 8K words, depending on the type of
Memory Unit mounted to the CPU.
Memory Units come in different types, such as RAM and ROM Units, and for
each type there are different sizes. (Refer to the Installation Guide for de-
tails.)
To store instructions in Program Memory, input the instructions through the
Programming Console, or download programming data from a FIT, floppy
disk, cassette tape, or host computer, or from a File Memory Unit if one is
mounted to the CPU Rack. Refer to the end of Appendix A Standard Models
for information on FIT and other special products. Programming Console op-
erations, including those for program input, are described in Sections 4 and
7.
3-11 TR (Temporary Relay) Area
The TR area provides eight bits that are used only with the LD and OUT in-
structions to enable certain types of branching ladder diagram programming.
The use of TR bits is described in Section 4 Writing and Inputting the Pro-
gram.
TR addresses range from TR 0 though TR 7. Each of these bits can be used
as many times as required and in any order required as long as the same LR
bit is not used twice in the same instruction block.
