Using TOP Server to communicate with PLC 5 via a ControlLogix Gateway

The driver will need to be set to Allen-Bradley ControlLogix Ethernet.

You will need to put in the correct route when your creating your TOP Server device.

This route is:

the IP address of the Ethernet Card on the Gateway,
followed by a 1 for the back plane,
next the slot number assigned to the DH+ card,
after this the port of the DH+ Card your using (A or B),
last, the node address of the PLC 5.

155.64.87.12,1,3.A.2, for example, is:

IP address 155.64.87.12
followed by the comma, 1, comma for the back plane.
The DH+ card is in slot 3 (4th position)
and we are using the A port.
The PLC 5 has a node address of 2 in this example.

Further information regarding Gateway to DH+ connections and routing can be found in the TOP Server Help file for the Allen-Bradley ControlLogix Ethernet Driver, under Appendices ⇒ Data Highway Plus Gateway Setup.

Using TOP Server to communicate with PLC 5 via a ControlLogix Gateway

It is possible for the TOP Server to collect data from several Allen-Bradley PLC 5 processors via a ControlLogix Gateway? The network will use Ethernet to reach the ControlLogix Gateway and Data Highway is used behind the Gateway.
