In Control Expert, assemble a Quantum rack:

Step

Action

Comment

1

In Control Expert, create a project.

Click File > New.

Result: The New Project window appears.)

2

Add a PLC from the New Project window.

For this example, double-click the 140 CPU 651 50 module. ( New Project > Quantum > 140 CPU 651 50).

3

In the Project Browser, double-click Local Bus.

Click Tools > Project Browser > Configuration > Local Bus.

Result: The Local Bus window opens, and the rack includes the processor you selected.)

4

Add a power supply to the Local Bus.

Drag the module to slot 1. ( Tools > Hardware catalog > Local Quantum Drop > Supply > 140 CPS 114 X0)

5

Add a 140 CRP 312 00 remote I/O head module to an available slot in the local rack.

Drag the module to slot 4. ( Tools > Hardware catalog > Local Quantum Drop > Communication > 140 CRP 312 00)

6

Use the same method to add a 140 NOC 780 00 distributed I/O head module to the Local Bus.

Drag the module to slot 5. ( Tools > Hardware catalog > Local Quantum Drop > Communication > 140 NOC 780 00)

7

Double-click any empty slot to add modules to the Local Bus .

This step is optional, but you can provide Ethernet transparency between the device network and the control network by adding a 140 NOC 781 00 control head module to the local rack.

8

Save the file.

Click File > Save.

The local rack in your Control Expert configuration should look like this:

Note that the Local Bus contains these modules:

  • power supply (140 CPS 114 •0)

  • CPU (140 CPU 651 50)

  • remote I/O head module (140 CRP 312 00)

  • distributed I/O head module (140 NOC 780 00)

  • control head module (140 NOC 781 00)

Rack Parameters

Double-click the 140 CRP 312 00 module in the Local Bus window to access these configuration parameters for the local rack:

NOTE: You can accept the automatically assigned IP address or change the IP address in the Control Expert IP Config tab.

Rack Considerations

Remember:

  • The copy/cut/paste commands are not available for the 140CRP31200 module.

  • You can cut or copy other devices in the local rack or the drop and paste them in any rack of the same type. You can perform these actions (cut, copy, paste) only in the same device editor. You cannot move objects from the local rack to the drop or vice-versa.

  • The number of the first slot in a rack is 1. Therefore, a 4-slot rack has slot numbers 1, 2, 3, 4.

NOTE: If you use a low-end CPU (140 CPU 6• 1••) (2 Mb or less), you can only install a maximum of 31 remote I/O drops. Of those 31 drops, you can only install a maximum of sixteen BMXCRA312•0 remote I/O drops. If you use a high-end CPU (140 CPU 6•• ••) (4 Mb or more), you can install a maximum of thirty-one BMXCRA312•0 or 140CRA31200 remote I/O drops.
