Hot Standby Controllers

These controllers support M580 Hot Standby systems:

  • BMEH582040, BMEH582040C, BMEH582040S

  • BMEH584040, BMEH584040C, BMEH584040S

  • BMEH586040(C),BMEH586040(C)C, BMEH586040S

Controller Module Front and Back Views

The three Hot Standby controller modules have the same external hardware features. The front of the module is on the left. The back of the module is on the right:

1 LED diagnostic display panel

2 Mini-B USB port for module configuration via PC running Control Expert

3 RJ45 Ethernet service port connector

4 RJ45 connectors that together serve as a dual port to the Ethernet network

5 SFP socket for copper or fiber-optic Hot Standby link connection

6 Hot Standby status link LED

7 SD memory card slot (behind door)

8 SD memory card lockable door

9 Cybersecurity rotary selector switch, with settings Cybersecurity Reset, Advanced, Standard

10 Hot Standby rotary selector, used to designate the controller as either controller A or controller B, or to Clear the existing Control Expert application

NOTE: The only visible difference between safety and non-safety-related controllers is that safety controllers are colored red.

Hot Standby Rotary Selector Switch

Use the rotary switch on the back of each M580 Hot Standby controller to designate the role that the controller plays in the M580 Hot Standby configuration:

Use the small, plastic screwdriver provided with the controller to set the rotary switch according to its role in a Hot Standby system.

NOTE: A plastic screwdriver is provided for your convenience; use it, or an equivalent, to change the position of the rotary switch. Avoid using metal screwdrivers.

Rotary switch settings include:

Position

Result

A

  • Designates the controller as controller A, as referenced in Control Expert and the T_M_ECPU_HSBY DDDT.

  • Assigns the controller IP address A on Ethernet RIO network.

B

  • Designates the controller as controller B, as referenced in Control Expert and the T_M_ECPU_HSBY DDDT.

  • Assigns the controller IP address B on Ethernet RIO network.

Clear

  • Clears the application in the controller, and places the controller into the NO_CONF operational state.

  • If an SD memory card is inserted in the controller, the application in the card is also cleared,

NOTE: Setting the switch for each Hot Standby controller to the same A/B position can cause a a conflict of controller roles.

Clearing Controller Memory

To clear a controller memory, follow these steps:

Step

Action

1

Set the rotary switch to Clear.

2

Power up the controller.

3

Power down the controller.

4

Set the rotary switch to A or B.

When you next power up the controller, if the remote controller is primary, the primary controller transfers the application to the local controller.

SFP Socket

Each controller module includes one Small Form-factor Pluggable (SFP) socket, to which you can connect either a fiber optic or a copper transceiver:

To insert a transceiver:

Step

Action

1

Check that the controller is powered off.

2

Position the transceiver so that its label is oriented to the left.

3

Press the SFP transceiver firmly into the socket until you feel it snap into place.

NOTE: If the SFP transceiver resists, check the orientation of the transceiver and repeat these steps.

To remove a transceiver:

Step

Action

1

Check that the controller is powered off.

2

Pull out the latch to unlock the transceiver.

3

Pull on the transceiver to remove it.
NOTE: For part numbers and other information regarding the available transceivers, refer to the description of controller Hot Standby link transceivers.

Each module comes with a stopper. When the SFP socket is not connected to a transceiver, cover the unused socket with the cover to keep out dust.

Grounding Considerations

Follow all local and national safety codes and standards.

The backplane for your M580 PAC is common with the functional ground (FE) plane and must be mounted and connected to a grounded, conductive backplane.
