Label on the Front of the Terminal Cover
The terminal numbers are written on the label on the front of the terminal cover. Terminal numbers are
unique three-digit numbers. They are used to locate terminals on the wiring diagram, etc. The highest
digit indicates the arrangement position of the terminal block; the lower two digits indicate the terminal
position within the terminal block (top right terminal is assigned "01" bottom left terminal is assigned
"36"). The terminals that cannot be used are indicated as " ".
PV, PV1, PV2: PV input, (RSP): RSP input(not used during program control), : unused terminal
Label on the Back of the Terminal Cover
Indicates the type of input/output signals for each terminal.
You can select the control modes from "single loop control", "cascade control", and "loop control with
PV switching" on the CX. The arrangement of the analog control input (PV) terminals are changed
depending on the control mode selected. The terminal arrangement for these three control modes are
written on the label on
Analog Control Input Terminal
.
