Integrators Model 325 URICA™ Universal Remote Interface Introduction Features & Benefits Provides standard Modbus RTU interface for up to 15 HART® devices Integrates Model 348 FIELDPAC TM Field-Mounted Controllers and SITRANSTM transmitters to various control systems using a Modbus interface for centralized control Uses standard RS232, RS422, and RS485 communication interfaces for low-cost connection to remote sites 2 Compatible with telephone, radio, and fiber optic modems for a broad range of remote connectivity options Simple installation with no configuration required reduces start-up time Provides remote read and write access to real-time process data Designed as an industrial grade package with 4 status lights and removable screw terminals resulting in a durable, user-friendly device Description The Model 325 (Universal Remote Interface for Control & Acquisition) URICA interfaces remote HART field devices such as the FIELDPAC 348 Field-Mounted Controller and the Siemens line of smart transmitters to a variety of control systems with Modbus RTU master interfaces. Through URICA, a user can access all FIELDPAC 348 loop data including setpoint, process, valve, and alarm information. The Model 325 also provides a connection to the Siemens line of transmitters to obtain their process information, range limits, damping, and loop data. URICA supports communication for up to 15 simultaneously connected HART field devices on a single twisted pair. Modbus masters can tie into multiple remote URICAs via standard phone, radio, and fiber optic modems. The front panel contains LED status lights, all terminal connections, and an RS232 serial port. Asynchronous communication between URICA and a MODBUS master is provided via RS232, RS422, or RS485 communication interfaces. DIP Switches, positioned on the rear of the circuit board, are set to establish the chosen communications format. 2.26 Designed for Division 2 locations, URICA can be mounted in an industrial enclosure, instrument cabinet, or on a desk. With only three simple steps necessary to create a fully operating system, the Model 325 has been designed for ease of installation. After power is applied, the Model 325 will automatically detect the connected HART devices and make their data accessible via Modbus. Both writing and reading HART device parameters, including any necessary error checking and acknowledgments, are managed by the Model 325 Universal Remote Interface.
