Connection Diagram

As shown in the figure below, connect multiple NT600S units to one PC. In an NT link (1:N), up to eight NT600S units can be connected to one PC port.

C200HX/HG/HE

RS-232C cable (max. length: 2 m), or directly connected RS-422A/485 cable

OMRON PC

While controlling machinery and monitoring lines, controls the NT600S units when necessary. C200HX/HG/HE can be used.

RS-232C/RS-422A converter unit, type NT-AL001

(*1) Total cable length: 500 m

(*2) For connection to an NT600S-ST121(B)-EV3, a separate power supply is required.

[Maximum Number of NT600Ss Connectable to One Port]

The maximum number of NT600S units that can be connected to the RS-232C port (built in the CPU) and the A and B ports in the communication board is indi- cated below.

￿C200HE:Up to 4 NT600S units per port (unit Nos. 0 to 3)

￿C200HG, C200HX :Up to 8 NT600S units per port (unit Nos. 0 to 7)

Reference When NT600S-ST121(B)-EV3 is connected in the configuration shown in the figure above, a separate +5 V (150 mA) power supply is required to drive the RS-232C/RS-422 converter units (NT-AL001). When NT600S-ST211(B)-EV3 is connected, the power to the converter unit can be supplied from the PT itself,

￿so no separate power supply is required.

When connecting the C200HX/HG/HE and an RS-232C/RS-422A converter unit, use a converter unit whose lot number is 15Y5 or later. Converter units of lot numbers previous to 15Y5 cannot be connected.
