Emerson DeltaV™ Redundant Controller

Benefits

Uninterrupted control operation. By installing redundant M-Series, S-Series, and PK controllers, you create a “safety net” that

protects your process from unexpected controller failures. In the event of a hardware failure, a backup controller is always available to keep your control and process up and running.

Online upgrades. Installing a redundant DeltaV controller allows you to upgrade your DeltaV system online.

New software can be installed into the backup controller online without disrupting operations.

Once the upgrade is complete, the backup controller is automatically configured and available, allowing you to switch to the new ffrmware without interrupting your process.

Once the switchover is complete, the original active controller can be upgraded. In addition, MQ controllers can be upgraded online to MX controllers.

SQ controllers can be upgraded online to SX controllers. This ensures that your system is always ready to expand as your control strategy evolves.

Automatic commissioning. The system automatically detects, commissions, and downloads spare controllers so you can safely replace equipment.

Add redundancy online by simply installing a new 2-wide backplane with system power and MQ, MX, SQ or SX controllers.

The SZ Controller Carrier or Dual Universal Safety Carrier provides 2 slots for SZ controllers, so there is no need to add anything other than additional SZ controllers.

PK controller carriers also provide 2 slots, so simply add a PK controller to an existing carrier.

The engineering database is automatically updated and the spare controller can be activated by simply assigning and downloading a controller redundancy license, all without interrupting the process.

There are no dip switches, jumpers or addresses to assign. The backup controller automatically assigns the proper backup address and starts working, protecting your process.

Bufferless Transitions The DeltaV controller is designed for bufferless control transitions from the active controller to the standby controller.

During this time, the output channels maintain their output state until the switchover is complete and the control module begins execution.

The control module uses signal status to ensure that all I/O channels are normal before taking control action on them.

All output signals are synchronized via the I/O readback function to ensure that control calculations are made based on the current output state.

When using CHARM or DeltaV Classic I/O cards with or without Foundation™ ffeldbus devices.

This ensures an uninterrupted transfer of control during switchover.

PAC8000 Control System Safe Choice for Process I/O Field-Mounted I/O

Benefits

Designed by experienced process engineers and dedicated to process applications, the 8000 I/O is simple to use-saving money and delivering value:

Lowest Cost Field Installation

The 8000 I/O replaces terminal blocks in the field junction box; sensors and actuators connect directly to the IO terminal blocks.

Single or redundant twisted-pair or fiber-optic cables replace multi-core cables in the control room, significantly reducing installation costs.

Cost savings can only be realized with field installations provided by the stable 8000 I/O.

Expandable

The 8000 I/O is perfectly suited for any operation with more than 8 I/O points. It is compatible with all controllers, from PLCs and PC-based systems to large DCS devices.

Low Cost of Ownership

– Hot-swappable, no downtime

– Automatic addressing – I/O can be removed and replaced without reprogramming

– Field wiring for direct I/O connection Field wiring terminals – no need for external wiring terminals

Field Installation of I/O

Today, engineers can install I/O anywhere in the field, saving money without sacrificing reliability.

The use of field-mounted I/O and open networks significantly reduces wiring costs while allowing access to needed diagnostic data.

The 8000 I/O System solves all practical problems so you can install the I/O bus on your equipment.

What is the 8000 I/O System?

The 8000 I/O System is a field installable I/O system that replaces the field junction box. It allows a group of any type of field device to be connected to a single network node.

These I/O nodes can then be connected together to create a fast, powerful and open I/O system.

PAC8000 Control System 8000-2/x Series Modular I/O

Field Terminals

Field terminals provide the connection between the I/O module and field wiring. They include optional fuses and circuit breakers. Mechanical keying systems prevent misconnection of I/O modules by the type of field terminals. Field terminals are mounted on the module base plate, one for each I/O module. These terminals are securely clamped to the I/O module and form a highly integrated electrical and mechanical assembly. Field terminals can be replaced during operation without removing the base plate and without interfering with the operation of other modules.

Base Plate

Mounted on flat or T or G DIN rails, base plates form the physical and electrical backbone of the 8000. supporting and connecting bus interface modules, power supplies, I/O modules, and field terminals, and supporting the internal Railbus address, data, and power lines. They provide terminals for LAN and field wiring shielded cables and can distribute bus field power to I/O modules. The I/O module backplane can support 4 or 8 I/O modules.

Power Supplies

Good power management is at the heart of a truly distributed I/O system. 8000 power supplies receive local unregulated power and then provide regulated power to the bus interface modules and I/O modules. Power redundancy is supported.

Bus Interface Module (BIM)

The BIM provides a serial data connection to a host controller, which can be a distributed control system (DCS), a programmable logic controller (PLC), or a PC running a software control package. with the BIM, you can adapt to the most common fieldbus protocols. At the same time, the BIM uses a fast internal bus for data transfer to I/O modules. You can control up to 32 I/O modules with just one BIM per node.

PAC8000 Control System I/O Modules — Overview

OVERVIEW

All I/O modules are connected to the high-speed Bus Interface Module (BIM) via a proprietary bus system called “Railbus”.

Up to 32 modules can be connected to one BIM. The module backplane provides the transmission medium for the Railbus.

At the same time, the modules can be connected to the bus by plugging them into the base plate. The connectors on the base plate also provide the power supply for the modules and, if necessary, for the field wiring.

Addressing of I/O modules

Modules are addressed by the bus interface module according to their location or slot and by combinations of 32 modules rather than individual module types.

Modules can therefore be removed and replaced by another module of the same type without “informing” the Bus Interface Module.

During the configuration process, the Bus Interface Module is informed of the location characteristics of each required module, regardless of whether the module is present at the time.

Therefore, if a module is replaced, the attributes of that “slot” remain with the bus interface module.

Critical modes

Output fail-safe mode

The output module can enter a fail-safe state. The module will enter this state if either of the following two reasons occur.

(1) The BIM forces the module into a fail-safe state by issuing a special command.

(2) The module has a configurable “timeout” parameter. This allows you to specify a maximum amount of time that communication with the BIM will cease.

Once this time is exceeded, the module will go to a fail-safe state. Different types of modules respond to fail-safe commands in their own ways, which are described separately in the following sections.
