The diagram above shows the C500-AD501 and C500-DA101 as examples of
Analog I/O Units.
System Configuration
The I/O READ and I/O WRITE instructions (READ and WRIT) cannot be used
for Units mounted to SYSMAC BUS Slave Racks. Set the C500-AD101 or
C500-DA501 for four-word operation whenever they are mounted to a SYSMAC
BUS Slave Rack. The C500-AD501 can operate only through the READ and
WRIT instructions and therefore cannot be mounted on a SYSMAC BUS Slave
Rack.

Using the Units
Turn OFF the PC power supply before connecting or disconnecting Units or wir-
ing. To reduce noise problems, wire the input and output lines through a duct
separate from the high-voltage and power cables.
Refer to Wiring in the section on the relevant Unit for detailed information and
cautions on wiring.
