DeltaV Licensing Guidelines

DeltaV I/O licensing for the VIM2 depends on the I/O cards

the VIM is emulating and follows that card type’s rules.

Programmable Serial Interface Cards

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 from 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.

See the M-series Serial Interface Series 2 product data

sheet for additional details.
