Emerson IC830M42H-DC92CA00 PACMotion Servo Motor

The Ovation controller hardware platform has evolved

over time beginning with the OCR161 model.

Specifications for the OCR1100 model are detailed in

the tables within this document. The OCR1100

controller model shares the same packaging concept

as the preceding OCR400 model. Migration programs

are available to update previous model control logic

and databases to the latest model. OCR1100 platform

provides backward hardware compatibility and can be

used as an OCR400 while retaining the ability to

provide full OCR1100 capabilities when installed in an

Ovation system release which supports them (i.e. Ovation 3.5 and above).

Make-before-break contacts ensure digital field instruments remain powered and the process is undisturbed.

Analog output signals are briefly driven by both cards for < 5 ms during switchover of the card.

Hardware Alerts automatically report hardware integrity errors for both the primary and secondary cards.

Any event that causes a switchover is also reported automatically through the system hardware alerts and is logged in the Event Chronicle.

Events that can cause a switchover include.

Hardware failure within the active card.

Communications failure between the active card and the controller.

Detection of a fault in the field wiring.

A switchover may also be initiated from the diagnostics explorer, and the health and status of both cards and 

their channels are available in the diagnostics explorer.

The system automatically commissions a new standby card.

In safe areas, failed cards can be replaced under power.

In hazardous areas, appropriate installation procedures must be followed.
