Unit.
Connected to C500-OD213 Transistor Output Unit
■External Connections
Refer to the Terminal Arrangement on page 3 and the Block Diagram on page 8 for external connections for each unit.
Example of connection to a PLC.
• Refer to the PLC operation manual before connecting the PLC.
• The number of wires can be reduced by using a PLC with dynamic outputs.

Example of Zero Suppression Usage: Descrtption Using
Negative Logic Model
The zero suppression function operates when the display is 0, RBI is
low and the decimal point is not lit.
Example 1: The RBI input and RBO output of each digit are open
when zero suppression is not being used.
Example 2: Wired as shown to display only 0 for the rightmost digit
when zero suppression is being used.
Example 3: Zeros are suppressed only for the digits on the left of
the digit where the decimal is lit when both zero
suppression and a decimal point are being used.
