VE4021 Emerson DeltaV M-series Zone 2 Remote I/O

Description:

VE4021 DeltaV M-series Zone 2 Remote I/O delivers big savings in the installation process. The compact, modular design allows you to cost-effectively meet your process needs. 

The Remote I/O subsystem consists of a System Power Supply and a Remote I/O Unit connected to an 8-wide I/O carrier with up to 8 simplex I/O cards. 

There are two versions of the Remote I/O Unit; the original Remote I/O Unit (RIU), and the Next Generation Remote I/O Unit 2 (RIU2). The RIU2 is a drop-in replacement for the original RIU back to DeltaV v13.3.1 and has the same functionality as the original RIU. 

Shared remote I/O for maximum flexibility I/O Targeting. The M-series Zone 2 Remote I/O Units supports targeting of Classic I/O to controllers on a per card basis. For example, a card can be owned by a controller, with different I/O cards owned by a different controller, with the limit that a Remote I/O Unit can support 4 controllers maximum. 

Each DeltaV controller can have up to 16 Remote I/O Units associated with it. 

The DeltaV system supports up to 300 remote I/O Units1 and they communicate on the same Ethernet network as the controllers and workstations.

The RIU2 supports 10/100MB communication on both primary and secondary ports.

Data Passthrough. The controller is equipped with the ability to pass smart HART® information from field devices connected to a Remote I/O Unit to any workstation node in the control network. 

This means you can take advantage of applications, such as AMS Device Manager that enable you to remotely manage the HART information contained in your HART equipped devices. 

Mounting. This plug-and-play system structure provides modular system growth with a single controller and is approved for remote mounting in a Class 1, Div 2 or ATEX Zone 2 environment. Refer to the System Power Supplies and I/O Subsystem Carriers product data sheets for additional information.

I/O Types and Capacity. The RIU2 support one I/O carrier of either Classic I/O or HART I/O. The Remote I/O Unit and I/O cards can be installed on either horizontal or VerticalPlus carriers. Any of the Classic or HART I/O cards may be utilized. The HART data from the I/O channels can be used in a control strategy, providing the user with the same experience using remote I/O as when using local I/O. 

Pulse Count Input card, Sequence of Events card, FOUNDATION Fieldbus cards, Profibus DP card, DeviceNet card, AS-i card, and Serial cards are not supported on the RIU2. I/O card redundancy is also not supported.

Starting with the DeltaV v14.FP3 release, the RIU2 supports the Series 2 Plus High-Density cards in simplex configuration. 

Easy plug-and-play installation 

-Self-Addressing. The M-series Zone 2 Remote I/O Unit is unique in its ability to automatically identify itself to the DeltaV control network. When the Zone 2 Remote I/O Unit is powered up, it is automatically assigned a unique address— no dip switches, no configuring—just plug and play! 

-Self-Locating. An M-series Zone 2 Remote I/O Unit’s physical location is easy to find. LEDs on the face of the Remote I/O Unit can be made to flash, providing a strong visual cue. 

-Automatic I/O Detection. The M-series Zone 2 Remote I/O Unit can identify all I/O interface channels located on the subsystem. As soon as an I/O interface is plugged in, the Remote I/O Unit knows the general characteristics of the field devices managed by that I/O interface. This reduces the “no-value engineering” associated with configuration—easy! 

Easy to use 

-Total Control. The controller(s) manages all control activities for the I/O interface channels. It also manages all communication functions for the communications network.

Time stamping, alarming, and trend objects are also managed within the controller(s). The controller(s) executes your control strategy. Information from an input channel on a Remote I/O Unit is received, control strategy applied, and data is sent to an output channel on Remote I/O Unit within 200 ms on average - assuming a 100 ms scan time for the I/O.
