Construct a High-Speed Data Acquisition System with Ethernet-Enabled Controllers and PLC

This introduces a system that uses Ethernet communications to acquire measured values, target values, and control output values from a controller installed on site into a PLC at high speed (ten units' worth within one second).

High-Speed Data Acquisition System with Ethernet-Enabled Controller

The Ethernet communication function that can be included with the UT55A/UT35A supports 100BASE-TX and 10BASE-T. By using the high-speed response mode that comes standard with the Ethernet function, the instruments can respond rapidly to requests for data from (upstream) PLC's and other devices. Since measured and other data are stored in the Ethernet-specific registers inside the UT, the data can be retrieved at high speeds by upstream devices by accessing those registers. Data that can be acquired with high-speed response are: PV values, SP values, OUT values, error information (PV input or A/D operation), alarm ON/OFF statuses, and other information such as RUN/STOP. Using the gateway function, you can connect with up to thirty-one other RS485-enabled (Modbus/RTU protocol) controllers via RS485. Of those, up to eight (including the UT55A/UT35A) can use high-speed response mode for high-speed data acquisition.

  • Chemical

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
