Introduction

The S-series Serial Interface provides a connection

between the DeltaV™ system and devices that support a

serial protocol, such as Modbus or Allen Bradley’s Data

Highway Plus.

The S-series Serial Interface is supplied with Modbus

software drivers pre-loaded. Additional drivers are available

to allow a wide variety of devices to be integrated directly

into the DeltaV controller’s I/O subsystem. Data can be used

by control modules or communicated to workstations as

SCADA tags for display and/or historizing. Like all DeltaV I/O,

the Serial Interface may be added online while the rest of

the controller I/O is powered up and in use.

DeltaV Serial Interface can also be installed as a redundant

pair for critical applications needing the highest availability.
