ABB FOUNDATION™ Fieldbus Linking Device LD 810HSE Ex V1.0

The FOUNDATION™ Fieldbus Linking Device LD 810HSE Ex is registered as class 42c of the HSE profile, there- fore providing the following functions:

–  It supports up to 4 separate FF-H1 links. In each of these links, the Linking Device operates as Link Master as well as SM Time Publisher.

– Identification of devices connected to the H1 links

– Configuration of connected H1 devices through System Management and Network Management via HSE

– Access to the function blocks of connected H1 devices via HSE

– Republishing of process data between H1 links

– Republishing of process data from H1 to HSE and vice versa
– Distribution of alarms and events sent by H1 devices

Functions

The LD 810HSE Ex is a gateway between an FF High Speed Ethernet (FF-HSE) subnet and FF-H1 links. It sup- ports device redundancy. The Linking Device meets protection class IP20 and is DIN rack mountable. It is pow ered by 24 V DC and supports Ethernet 10 Mbit/s or 100 Mbit/s.

H1 Links

• System Management Manager • Network Management Manager • FMS Client for object access • Publisher and Subscriber of process data • Support of alarms and events • Link Master • SM Time Publisher: The LD will distribute the system time, i. e. the base for alarm time stamps. • Accesses to an H1 port MIB from H1 network is supported but write access from the H1 net- work is restricted.

H1 Live List

• The H1 live list contains all H1 devices that are active on the H1 link. • For each H1 device, the Linking Device records the node address, the PD tag, and the device ID.

Built-in Web Server

General information about the Linking Device can be queried via the web pages of the built-in web server. This requires a standard web browser sup- porting JavaScript on a PC that is connected to the Linking Device via Ethernet.

Installation in Hazardous Locations

The LD 810HSE Ex is suitable for use and installa- tion in areas with potentially explosive atmosphere in accordance to both the Division model (North America) and the Zone model (Europe and IEC coun tries) of hazardous locations.

Hazardous Location - North American Approval (cULus)

If indicated on the device label, the LD810 HSE Ex is suitable for use in Class 1, Division 2, Groups A, B, C, and D hazardous or non-hazardous locations.

The Linking Device does not meet the requirements of impact protection or IP54 (according to IEC 60529). Thus, it must be installed in a protective enclosure that meets the requirements for re sistance against impact and IP as stated in section 26.4 of IEC/EN 60079-0. This enclosure must be fully mounted and intact. If the enclosure is damaged, the operation is not permitted.

Hazardous Location - European and International Approval (ATEX, IECEx)

The equipment was assessed based on the follow- ing standards and editions: a) IEC 60079-0:2011 Ed. 6, modified Cor. 2012 + Cor. 2013 / EN 60079-0:2012 + A11:2013   b) IEC 60079-11:2011 Ed. 6 + Corr. 2012 / EN 60079-11: 2012 c) IEC 60079-15:2010 Ed. 4 / EN 60079-15: 2010 If indicated on the device label or by technical documentation, the LD 810HSE Ex is suitable for use in gas- Ex atmospheres of Zone 2 in the explo- sion groups IIA, IIB and IIC in temperature class T4, if accommodated in a tested enclosure. 

 • IECEx marking for explosion protection: Ex nA [ic] IIC T4 Gc 

 • ATEX marking for explosion protection: II3G nA [ic] IIC T4 Gc The Ex protection method [ic] corresponds only to the FF-H1 fieldbus interfaces.

The LD 810HSE Ex complies with the applicable standards and regulations and meets the require- ments of Directive 2014/34/EU. The requirements for mounting the device as part of the system in potentially explosive atmospheres (e. g. IEC/EN 60079-14) must be strictly adhered to.

Integration into the ABB Ability™ IT System Structure

Within a typical 800xA system structure as shown in the Figure below, a FOUNDATION™ Fieldbus subsystem is linked to the control system via the HSE subnet. The Linking Devices serve as gateways between the field devices on the H1 links and the HSE subnet.
