Yokogawa Unveils Enhanced DXAdvanced DAQStation

The latest version of the Yokogawa DXAdvanced DAQStation range of data acquisition (DAQ) and display stations - the DXAdvanced R4 - features a number of new enhancements. These include an advanced security option that provides 21 CFR Part 11 compliance, multi-batch capabilities, a Profibus interface and the new DAQManager data management software. The advanced security option (AS1) incorporates all the features required to provide secure electronic records to comply with the US Food and Drug Administration's 21 CFR Part 11 standard, including controlled system access, active directory password management, electronic signatures and an audit trail.

The DXAdvanced R4 has evolved from Yokogawa's paperless recorder technology to become a complete DAQ station with a built-in panel. It incorporates integrated display, recording and communication functions. Two models are available: the DX1000 with a 5.5in (14cm) LCD panel and up to 12 input channels; and the DX2000 with a 10.4in LCD panel and up to 48 input channels. The new models also feature high-capacity internal storage, with 400Mbyte of secure non-volatile flash memory to support the uninterrupted recording of more data over longer time periods.

The multi-batch function allows the user to record predefined channel groups to separate data files with independent start and stop control. Up to six batches can be created on the DX1000 and up to 12 on the DX2000. The DXAdvanced R4 offers custom display screens that allow the user to arrange field displays along with trend curves, bar graphs and other visuals. The DAQStudio builder software can be used to create and edit custom display screens on a PC. The DAQManager software allows the user to manage measured data from the DXAdvanced DAQStation and Yokogawa's MVAdvanced range of paperless recorders on a PC.

Data loaded onto DAQManager can be searched for by data/time, tag name, batch name or other criteria. The Profibus interface, along with support for Profibus-DP and Ethernet/IP protocols, enables the DXAdvanced DAQStation R4 to be integrated into end-user applications to provide a wider range of functions than DAQ and recording. In particular, it can be used with Yokogawa's MW100 DAQ system and other vendors' input/output products to provide many additional input channels. Then, using the optional maths and events functions of the DXAdvanced DAQStation, the unit can be used to initiate actions or alarms based on the acquired data.
