Automatic commissioning. The system automatically detects,

commissions, and downloads a standby controller so you can

safely replace a unit in the field. Redundancy can be added

online by simply installing a new 2-wide backplane with a

system power supply and MQ, MX, SQ, or SX controller on it.

The SZ controller carrier, or the Dual Universal Safety Carrier,

provides 2 slots for SZ controllers, so there is nothing to add

other than the additional SZ controller. The PK controller carrier

also provides 2 slots, so simply add an additional PK controller

to the existing carrier. The engineering database is updated

automatically, simply assign and download the controller

redundancy license to activate the standby controller, all with

no impact to your running process.
