When wiring inputs, apply the following points to avoid noise interference and
optimize Analog Input Unit performance.
• Use shielded twisted-pair cable for external connections and power lines.
• Route input cables separately from the AC cable, and do not run the Unit's
cables near a main circuit cable, high voltage cable, or a non-PC load cable.
• If there is noise interference from power lines (if, for example, the power supply
is shared with electrical welding devices or electrical discharge machines, or if
there is a high-frequency generation source nearby) install a noise filter at the
power supply input area.
The IR and DM word addresses that each Analog Input Unit occupies are set by
the unit number switch on the front panel of the Unit.

Note 1. Switches A to F can be set for the C200HX/HG-CPU5j-E/6j-E. Setting
numbers A to F for C200H, C200HS, C200HE, or C200HX/HG-
CPU3j-E/4j-E PCs will cause an I/O UNIT OVER error and the Unit will
not operate.
2. If two or more Special I/O Units are assigned the same unit number, an I/O
UNIT OVER error will be generated and the PC will not operate.
