One-to-N Computer Connections
Up to 32 OMRON PLCs, including CPM2B PLCs, can be connected to a host
computer.

Note
1.
The NT-AL001-E must be supplied externally with 5 V DC. When an NT-
AL001-E is connected to a CPM2B PLC, pin 6 of the CPM2B’s RS-232C
port su5 V DC and an external power supply is not necessary.
When the NT-AL001-E is connected to a host computer, it is necessary to
supply 5 V DC from an external power supply.
If an NT-AL001-E is connected to the CPM2B’s RS-232C port, only one
Expansion I/O Board can be connected to the CPU Board because the NT-
AL001-E draws its 5-V DC power from the CPU Board.
Use an XW2Z-070T-1 (0.7 m) or XW2Z-200T-1 (2 m) cable to connect the
NT-AL001-E to the CPM2B’s RS-232C port.

The 3G2A9-AL004-E requires an external AC power supply (110 V AC or
220 V AC).
