Allen-Bradley PLC-5 via Data Highway - 5136-SD-PCI Test

Note: For full details of the 5136-SD-PCI board, please refer to its hardware guide.

Once the 5136-SD-PCI board is installed, you can tell whether or not it is functioning correctly by monitoring its LEDs. You will not need to remove your computer's cover to do this, as the board's LEDs are visible at the back of the machine.

The board has two LEDs, the Network LED and the System LED. The first time you start up the computer with the board installed, the System LED will be red. When Plant SCADA successfully downloads the communications firmware to the board, it turns the System LED off. If the loader does not run successfully, the System LED will remain red.

The Network LED displays a flickering green whenever the card is active (transmitting) on the network. The Network LED should never turn off as long as there is a node on the network. If it does not display green, check your hardware or network cable.
