Product Overviews

    Overview:

    Yokogawa presents a brief tutorial on configuring Stardom RTU to communicate with EJX Multivariable Pressure and Temperature transmitter via Modbus RTU over RS485. Appropriate function blocks and settings within Logic Designer are covered in order to read in the primary three variables DP, SP, and Temperature. Also a quick review of FieldMate and Kepware OPC Server are shown as examples of ways to review and change the settings of the EJX 910 Modbus MV transmitter.
