Rosemount Hart 375 Manipulator

I. Product Overview:

Emerson Rosemount (Rosemount, USA) Hart 375 handheld communicator, Emerson process management of the new 375 field communicator, it supports not only the HART communication protocol, but also the Foundation fieldbus communication protocol, and has the characteristics of universal, reliable, portable, intrinsically safe and easy to upgrade. These characteristics will quickly make 375 hａnd manipulators a new standard.

2. Unique performance:

1. The new standard of Rosemount Hart 375 is a new generation of communicator developed on the basis of more than 10 years'application experience of 275 Hart communicator and further needs of users.

2. Following the successful application of 275HART communicator, Emerson Process Management has introduced a new 375 field communicator, which supports both HART protocol and Foundation Fieldbus protocol. It is universal, reliable, portable, intrinsically safe and easy to upgrade. These characteristics will quickly make 375 hａnd manipulators a new standard.

3. At present, more than 100 equipment suppliers provide more than 600 HART and FF fieldbus equipment protocols. Rosemount Hart 375 Manipulator supports Emerson's PlantWeb plant management and control network technology, and combines 17 years to provide HART users with on-site experience in configuring and maintaining their instruments and valves. The powerful field bus branch diagnostic function of 375 hａnd manipulator is based on Emerson's extensive experience of thousands of field bus devices worldwide.

3. Product characteristics:

1. Universality

Rosemount Hart 375 handset supports all HART #ａnd Foundation Fieldbus devices. In addition, there is ample room for your future development. Users can upgrade locally. Users can download the latest version of HART and Foundation fieldbus from the Internet to upgrade 375 handsets locally.

2, safety

Rosemount Hart 375 is the only field operator that meets all intrinsic safety requirements. Including ATEX-compliant, CENELEC, FM, CSA and FISCO.

3. Firm and reliable

That's one reason why he's called a'hand-held device'. Some work must also be performed on equipment. 375 hａnd operaters are specially designed to connect with AMS interface for adverse working conditions in factories. 375 hａnd operaters can be connected with AMS equipment management software interface. Data transmission of HART instruments and valves is carried out between equipment management software and hａnd operaters.

VII. Notices for upgrading:

HART375 handheld communicator produced by Rosemount is a handheld communicator supporting HART protocol equipment. It is mainly used to configure, manage, maintain, adjust and monitor the process variables of HART intelligent instruments in industrial field. It can be comparable to ROSEMOUT-375 handheld communicator with similar functions, low price and good compatibility. With EasyUpgrade, the product can be upgraded for free for three years.

Note when upgrading: When DD files do not match the field transmitter, there may be problems with some functions.

In the process of 375 automatic upgrade, you must pay attention to the installation of random software in English operating system (using Win2000) in order to install successfully.

Perform the following steps to enter PC control mode:

1. From the main menu of HART 375, select Listen for PC.

2. Align IrDA interface of 375 field communicator with PC IrDA interface.

3. Use programming tools or AMS software package intelligent device manager to complete the necessary transmission; more detailed information can be referred to the online help of programming tools.

4. Click EXIT to close PC application control. If the new system software is downloaded to the system card of the 375 field communicator, the internal Flash will be updated.

8. The commonly used models are:

Rosemount 375HR1ENA9, Rosemount 375HR1ENAU, Rosemount 375HR1EKL9, Rosemount 375HR1EKLU, Rosemount 375FR1EKLU (HART+FF protocol)

1. Basic 375 includes field communicator device, system card, lead with connection terminal, suitcase, usage introduction, user manual, 375 resource CD, stylus and installation belt.

2. Users need to consider this option after they have 375 power supply/charger. Note: 375 battery pack can only be used with 375 power supply/charger.

3. Fast Upgrade allows users to add new system application software and device description (DD) to 375. If this performance is not available, the system card must be sent to the service center when upgrading.

4. For normal field applications, the battery pack can maintain power supply for 8 hours after it is fully charged. If more than 8 hours, a second battery pack is recommended.
