I/O Card Redundancy

Redundant I/O cards are available for critical applications.

The same card can be used in simplex or redundant

applications. When installed on a two-wide redundant terminal

block, the cards are recognized as a redundant pair by the

controller. The controller scans each card and determines which

card is acting as the active interface. When a fault is detected,

the system automatically switches to the standby I/O card.

DeltaV Control modules reference simplex and redundant

I/O channels identically and there is no special configuration

required to take advantage of redundancy.

Switchover of a redundant I/O card is completed within

two scans of the I/O bus. Make-before-break contacts ensure

digital field instruments remain powered and the process

is undisturbed. Analog output signals are briefly driven by

both cards for < 5 ms during switchover of the card.

Hardware Alerts automatically report hardware integrity errors

for both the primary and secondary cards. Any event that

causes a switchover is also reported automatically through the

system hardware alerts and is logged in the Event Chronicle.

Events that can cause a switchover include.

All I/O cards are enclosed in a common form factor that plugs

into the I/O interface carrier. The housing is clearly labeled with

the enclosed I/O card type. All cards have power and internal

error indicators. Eight-channel cards have clearly visible channel status LEDs.

All cards meet ISA G3 corrosion specifications by the careful

selection of superior electronic components and the use of conformal coating.

Pulse Counters are available on most DI cards. The supported

maximum frequency varies from 0.1 Hz on AC signals to

75 or 120 Hz on 24V DC inputs. For higher pulse counts,

up to 50 KHz, use the Multi-Function card’s high speed pulse input.

The DeltaV system provides control module level time

stamping for log events and alarms. For greater event

resolution, the 16-channel Sequence-of-Events DI card

can provide signal driven events to a resolution of +/- 0.25 ms

per card, or within 1 ms per controller. Please refer to

the Sequence-of-Events PDS for more information on

Sequence-of-Event data collection and system options for this feature.

on which all I/O related components are installed.

• Bulk AC to 24V DC power supply for field devices.

 An I/O interface consisting of an I/O card and an

I/O terminal block.

• A variety of analog and discrete I/O cards enclosed

in a common form factor that easily plugs into the

I/O interface carrier.

• A variety of I/O terminal blocks mounted on the I/O interface

carrier that can be pre-wired before I/O card installation.

The DeltaV system provides control module level time

stamping for log events and alarms. For greater event

resolution, the 16-channel Sequence-of-Events DI card

can provide signal driven events to a resolution of +/- 0.25 ms

per card, or within 1 ms per controller. Please refer to

Simple Maintenance

RSTi-EP lays a strong foundation for installation, machine

commissioning and service applications with robust and

easy-to-use signal connection components. LEDs on the

module and each channel help operators to quickly and

easily determine I/O health and quickly diagnose any

system failures.

Intutive Integration

The RSTI-EP features outstanding performance and

response time, with the high-speed system bus reading

up to 256 DI/ DOs in 20 microseconds. It offers intuitive

I/O mapping for quick and easy integration into

your control application, as well as maximum power

reserves for future applications. RSTi-EP features faster

backplane speeds than the original RSTi I/O and perfectly

responds to growing complexity in machine and factory

automation thanks to powerful flexibility and a consistent

user interface.

High Availability

With the PNS101 network adapter, RSTi-EP supports

PROFINET System Redundancy (PNSR). This enables

synchronized independent controllers to service the I/O

and transition from active to back-up controller without

interruption. With controllers and processes resilient

from physical disruption, you can consider unplanned

downtime a thing of the past.

Consistent I/O cabling interfaces make installation faster

and more reliable. Color-keyed connectors allow for

fewer cabling errors and noticeably shorter installation

times. Better still, no tools are required for installation or

removal of I/O wiring connectors, saving time and effort.

Entire machine modules can be cabled and transferred

into production through a streamlined commissioning

process. Bulk swing-arm kits are available to enable cable

pre-assembly, offloading repetitive tasks for your team

during panel assembly.

Plug and Play Installation

A single row connection level

facilitates wiring, installation, and service. Separate power

supplies for inputs and outputs reduce the number of

power feed modules needed and save space; additionally,

specific sections can be activated or deactivated without

affecting production thanks to the independence of the

input and output power busses.

Remote, Real-time Diagnostics

With the RSTi-EP’s integrated web server and advanced

diagnostics, failures in the system can be identified

remotely, eliminating the need to travel to the machine,

saving both time and money. The web server lets the

operator view diagnostic faults and upgrade firmware

over the web– simplifying start up, increasing availability

and productivity without the need for additional tools or

software. Additionally, actions can be taken within the

application feeding off of the diagnostic information. It

is simple to prioritize service trips as critical or routine

maintenance without stepping out of the control room.

 It can accommodate up to 64 modules and 1024 I/O

points per drop, while its 11.5 mm I/O slices maximize

limited cabinet space. By adopting the most compact

I/O system on the market, it’s possible to incorporate

smaller cabinet sizes into user-friendly system designs.

You can even eliminate external components by using

optional potential distribution modules to provide

easy connections to input power, output power, and

functional earth.

Higher Performance in Half the Space

RSTi-EP combines powerful technology and a modular,

compact form factor to deliver higher performance and

maximized productivity in today’s connected automation

systems. The RSTi-EP remote I/O system is well suited

for Industrial Internet enabled applications. It features

an extended operating temperature range, enhanced

diagnostics, plug-and-play connectivity and high channel

density– all designed to simplify machine design and

maintenance. Advanced diagnostics make RSTi-EP ideal

for remote applications, especially those where I/O can be

difficult to reach. RSTi-EP I/O is easily expandable, so you

can adapt and extend coverage as your system evolves.
