2.2 Name and Function of Each Part of the Controller
 Indication of PIO pattern number
If you have multiple systems and a different PIO pattern is used for each system, it is recommended
that you specify an applicable PIO pattern number on each controller to prevent confusion.
 Explanation of input/output signal pattern
NPN --- Sink type
PNP --- Source type
 Explanation of motor drive-power cutoff circuit
INT --- ACON-C [Internal drive-power cutoff relay type]
EXT --- ACON-CG [External drive-power cutoff relay type]
 On notational convention of types of actuators to be connected
The supported actuator type is specified as in the example below. Check that the correct actuator is
used when connecting cables.
Example: RCA-RA3C-I-20-10-50-A1-S
(Note) Refer to the operation manual for each network (CC-Link, DeviceNet and ProfiBus) as well for the
detailed explanation of the network connection specifications.
