Description

CE4006P2 M-series Serial Interface Series 2

The DeltaV controller auto-senses the Serial Interface and presents the configuration options. Online help makes this
interface a snap to configure. After a simple point-and-click configuration exercise, your integrated solution is up and running.
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-ofthe-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 redundancy to an existing system, providing the slave device supports
redundant serial ports. DeltaV redundant I/O uses the same Series 2 I/O cards as non-redundant I/O. This allows you to
leverage your investment in installed I/O and in I/O spares. No additional configuration is required.
Autosense of redundancy. The DeltaV system autosenses redundant I/O, which greatly simplifies the task of adding
redundancy to the system. The redundant pair of cards is treated as one card in the system tools.
Automatic Switchover. Should a primary I/O 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 serial card supports the following features using the Modbus protocol:
Reading input data from Modbus coils, input status, holding registers and normal input registers.
Writing output data to coils and holding registers.
Output data can be written in single coil, register mode, or complete data set mode. This output mode is a configurable parameter.
Input data can be read in as a complete data set, providing the best performance.
The serial card supports the input and/or output of 16 different data sets per serial port, for a total of 32 data sets per Serial Interface.
Serial dataset registers can be referenced directly in control modules as analog or discrete I/O providing fast easy data
exchange with the serial device. Direct module-to-Dataset/ register references are recommended for control signals.
Alternatively, users can read multiple registers form a Dataset into a single “marshalling” module at the cost of a single DST.
Marshalling modules provide a cost effective way to integrate serial data from analyzers and other data sources. Serial dataset
registers can also be passed as SCADA values directly to Workstations and Continuous Historians without consuming DST’s.
