Emerson M-series Virtual I/O Module 2 Interface Cards

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.

DeviceNet Interface Cards

In DeltaV v12 and later, the number of DSTs per connected

DeviceNet device will be 1 DST in most cases. The DST type

counted will be the most valuable type used to reference

a signal for each device. If references are made to more

than 16 signals from a device, additional signal references

beyond the 16th reference will each count as a DST.

A motor starter, for example, with 4 to 5 signal references,

will consume 1 DST (typical an AI or DO DST). A remote I/O

island will consume 1 DST for the first 16 signal references,

and 1 DST for each additional signal reference beyond the

16th signal reference.

Profibus DP Interface Cards

In DeltaV v12 and later, the number of DSTs per connected

Profibus DP device will be 1 DST in most cases. The DST

type counted will be the most valuable type used to

reference a signal for each device. If references are made

to more than 16 signals from a device, additional signal

references beyond the 16th reference will each count

as a DST. A motor starter, for example, with 4 to 5 signal

references, will consume 1 DST (typical an AI or DO DST).

A remote I/O island will consume 1 DST for the first 16

signal references, and 1 DST for each additional signal

reference beyond the 16th signal reference.
