Introduction 

 Are you looking for an efficient, yet robust, I/O subsystem? M-series FOUNDATION Fieldbus I/O is a modular subsystem that communicates digitally with field devices, increases your input/ output capacity, and gives you access to more information about your process than conventional I/O subsystems. If you want an efficient, economical, and secure process control system, use DeltaV™ M-series FOUNDATION Fieldbus redundant I/O. It greatly enhances device diagnostics that affect your control strategy and alerts operators to device malfunctions. The modular design of M-series FOUNDATION Fieldbus I/O offers flexibility during installation. It’s designed to be installed in the field, close to your devices. M-series FOUNDATION Fieldbus I/O is equipped with function and field-wiring protection keys to ensure that the correct I/O card is always plugged   into the corresponding terminal block. Modularity,   protection keys, and increased input/output capacity make M-series FOUNDATION Fieldbus I/O a smart choice for your process control system.

Benefits 

 Increases input/output. Use M-series FOUNDATION Fieldbus I/O instead of Classic I/O to increase information flow.   Take advantage of FOUNDATION Fieldbus digital communications to access additional information from   your smart devices. Get more information over one wire   than over multiple wires, as with Classic I/O. Takes advantage of all smart device capabilities. Increase your ability to communicate with your devices using DeltaV M-series FOUNDATION Fieldbus I/O; field device status is updated continuously. For multi-variable devices, all process variables are available on the single fieldbus connection. Facilitates multi-drop 16 devices on one port. Save on wiring expenditures by installing M-series FOUNDATION Fieldbus I/O in the field, close to the actual field devices. Mounting the controller with the I/O further reduces your wiring costs by eliminating   the need for long runs of multi-cores. Multi-dropping up to   16 devices on one port reduces your wiring expenses substantially. The integrated design of the M-series FOUNDATION Fieldbus I/O can eliminate the need for marshalling panels. This saves you even more time and money. Features secure uninterrupted control. A DeltaV system offers back-up link active schedule (LAS) to ensure secure control when upgrading a card or in the case of card failure.   LAS control is automatically transferred to the backup device when upgrading or experiencing card failure. Control is automatically transferred back to the H1 Interface Card   when the system detects a new card. This process requires   no user interaction. 

Product Description 

 The I/O card is enclosed in a DeltaV-designed common form factor that plugs into the I/O interface carrier. The housing is clearly labeled with the enclosed I/O card type. Clearly visible LEDs on the top of the I/O card display the power, error,   and status to the two channels included in the I/O card. The Fieldbus I/O Card meets ISA G3 corrosion specifications by using superior electronic components and conformal coating. Redundancy Made Easy. The active and standby I/O cards   are connected to the field at the redundant terminal block.   When a fault is detected, the system automatically switches to the backup I/O card. The reliability rating of the terminal block is greater than the high reliability of the I/O cards. The controller scans each card of a redundant pair.   Incremental controller loading is a function of the number of redundant cards. In addition, the redundant cards have dedicated communication between the pair and the backup card monitors the health of the active card. Configuration of redundancy is not required as the DeltaV system automatically recognizes the redundant pair of cards and assigns a device signal tag (DST) to the channels on the primary card. Signals referenced for each connected FOUNDATION Fieldbus device will count at most 1 DST. The DST type counted will be the most valuable type used to reference a signal for each device. For example, a device with 1 AI signal reference and   1 AO signal reference will count as 1 AO DST. Switchover time for redundant I/O is minimal, and the process will be undisturbed. An alarm on the integrity error for the primary notifies the operator of a switchover. The backup card is also monitored for integrity alarms. Events that can cause a switchover include. 

 y Hardware failure within the active card. 

 y Communications failure between the active card   and the controller. 

 y Removal of the active card from the carrier.

 y Detection of a fault in the field wiring. A switchover may also be initiated from the diagnostics explorer, and the health and status of both cards and their channels are available in the diagnostics explorer. The system automatically commissions a new standby card.   In safe areas, failed cards can be replaced under power.   In hazardous areas, appropriate installation procedures must be followed. The M-series FOUNDATION Fieldbus I/O subsystem includes: y H1 interface card and simplex terminal block, or y 2 H1 interface cards and redundant terminal block.EMERSON VE4017P0
