Extends the life of existing equipment. Enhance existing

capabilities—don’t replace them. Many plants have a variety

of devices already installed. With the Serial Interface you are

able to effectively interface a DeltaV system with existing

PLCs or other serial devices. This means that you can layer

the state-of- the-art process control offered by a DeltaV

system on to the devices you already have in place.

1:1 Redundancy for Serial I/O cards. You can add

Serial interfaces as simplex cards or redundant pairs.

The interfaces automatically detect the presence of

the redundant terminal block and are autosensed by

the system as a redundant pair. There is no additional

configuration. Use redundant Serial interfaces with slave

devices that support redundant serial ports.

Automatic switchover. Should a primary Serial

Interface card fail, the system automatically switches

to the “standby” card without user intervention. The

operator is given clear notification of a switchover at the

operator display. The standby card continually polls the

slave devices for diagnostic to confirm its ability to take

over communications.
