The Device Drivers are software drivers built into WebAccess to provide communications with PLCs, DDC systems, IO and automation hardware. The engineer or technician "configures" device drivers with Fill-in-the-Blanks forms that update the WebAccess database. No programming is required by users, operators, technicians or engineers to implement a device driver. WebAccess Device drivers are objects that use a database to update the IO Tags.
IO Tags, Blocks and the Internal Tags (Calculation, Constant and Accumulation Tags) are object that reside on SCADA nodes. The SCADA node acts a Tag Server to clients to provide real-time data.
