VS3202   DeltaV SIS™ Logic Solver

Flexible deployment. Traditionally, process safety systems
have been deployed either separate from the control system or
interfaced to control systems via engineered interfaces based
on open protocols (e.g. Modbus). However, most end users
require a higher integration for configuration, maintenance,
and operations environment. DeltaV SIS can be deployed
either as interfaced to any DCS or integrated with DeltaV DCS.
Integration is accomplished without scarifying functional
separation as safety functions are implemented in separate
hardware, software, and networks while being seamlessly
integrated at the workstations.
Easy Compliance with IEC 61511. IEC 61511 demands
rigorous user management and the DeltaV SIS process safety
system provides it. IEC 61511 requires that any changes
made from an HMI (e.g. to a trip limit) be extensively vetted
to ensure that the right data is written to the right Logic Solver.
The DeltaV SIS process safety system automatically provides
this data verification.

Scales to fit any size application. Whether you have an
isolated wellhead or a large ESD/fire and gas application,
the DeltaV SIS process safety system scales to provide you
with the safety coverage you need for your SIL 1, 2 and 3 safety
functions. Each SLS 1508 Logic Solver has dual CPUs and
sixteen channels of I/O built into it. This means that no
additional processors will ever be required to expand the
system, since each Logic Solver contains its own CPUs.
Scan rate and memory usage are constant and independent
of system size.
SIL 3-rated. DeltaV SLS 1508 Logic Solvers are installed in
redundant pairs for increased process availability of your
SIS loops.
