Yokogawa says its Daqstation paperless recorders are the first to support Foundation Fieldbus communication standards as well as talking to analogue devices
The Yokogawa Daqstation DX100/DX200 family of paperless recorders are the first instruments of their type to support the Foundation Fieldbus bidirectional digital communication standard.
Each unit can accept up to eight Foundation Fieldbus devices, making it ideal as a 'starter pack' for Fieldbus applications. Fieldbus connectivity allows the recorders to receive measured values from connected Fieldbus field devices, display the data in a wide variety of formats, and store this information to a network or other storage media.
The Daqstation recorders can also accept a wide range of analogue values from external sensors or measuring instruments, and can interface to the Fieldbus network, allowing non-Fieldbus devices to be available on the Fieldbus link.
The recorder also has an Ethernet port as a standard feature, allowing connection to other systems via OPC.
The unit can act as an LAS (Link Active Scheduler), allowing Fieldbus networks to be created without the use of a DCS (Distributed Control System).
In addition, the Daqstation can take over as the LAS in the event of a failure to another system.
The Daqstation DX200 has a 10.4-inch colour liquid-crystal display, fits a 288 x 288 mm panel cutout, and offers up to 30 channels.
The compact DX100 has a 5.5-inch LCD, fits a 144 x 144 mm cutout, and offers up to 12 channels.
Both units offer a powerful range of display capabilities including trend curves, digital value tables and bar graphs.
The new product represents another 'first' for Yokogawa, and maintains the company's position as one of the leading vendors of Foundation Fieldbus products.
