Page 9: Overview
2. OVERVIEW PRODUCT SUMMARY The Chipkin™ CAS2500-01 Modbus® RTU Data Client is a device that connects to Modbus® RTU as a Modbus RTU Master, and reads and stores the data. The data client operates by reading data from the configured registers and stores the values in an internal database. These values can then be logged to an archive file or can be accessed via the data clients REST API as XML, JSON, or CSV data using HTTP Get requests. -
