PACSystems VersaSafe

Distributed Safety System with High Availability

At Emerson, we understand that production has
to become more efficient by enabling the opera­tor to work closer to the process without com­promising operator safety.

VersaSafe adds SIL3 machine safety capabilities
to our high performance platforms strategy.
By combining secure network connectivity,
certified safety function blocks and an easy to
use graphical programming environment,
customers can efficiently integrate standards­compliant safety capabilities to their equipment
while meeting increasingly stringent regulatory
requirements.

In addition to enabling safety functionality,
VersaSafe provides enhanced I/O control
capabilities suitable for optimization of high-end
machines.

Higher Availability

The VersaSafe distributed safety system provides a
TÜV-certified SIL3 machine safety solution that focuses on the
critical control requirements of the production environment:
safe operation and greater uptime of the manufacturing
equipment.

High availability is delivered by integrating industry-proven
PROFINET with optional media redundant protocol (MRP)
and multiple cable media options. Machine repair times are
reduced by the ability to put a machine in a safe state without
fully
powering down the equipment, enabling faster start-up after
a repair.

Simplified Architecture

VersaSafe is a member of the PACSystems control family that
delivers increased performance, greater uptime and lower total
cost of ownership. Leveraging PACSystems’ distributed I/O

architecture and single point of connect capabilities, VersaSafe
enables efficient development of high-performance
modular machines.

A single network carries standard and safety I/O; this simplifies
wiring without compromising safety.

Simplified Engineering

To minimize engineering efforts, Emerson provides a
comprehensive set of tools and services as part of the
VersaSafe solution, including a library of certified safety
function blocks, the ability to seamlessly integrate safety and
standard capabilities and a robust set of integrated
development and commissioning diagnostic utilities.

Best-in-Class Scalability

We have eliminated the need for a separate safety CPU,
enabling a highly distributed safety I/O configuration that is
both cost effective and maintains highest levels of
performance as the system grows. Emerson has also addressed
customers’ needs to make online changes to safety logic.
Large production lines, in particular, will realize considerable
benefit in the ability to update a portion of the safety logic
witout stopping the controller. Smaller machines benefit from
right-sizing the safety I/O needs without bearing the overhead
of a separate safety controller.
