WITS is the acronym used for the Water Industry Telemetry Standard, a common telemetry protocol first developed by UK water industry companies. The protocol was created in an attempt to provide greater interoperability between Field Devices and Master Stations from different manufacturers. It is now supported by many vendors, including Schneider Electric.
Field Devices and Master Stations can only be sold as WITS verified if they pass a series of extensive tests that are set by the WITS Protocol Standards Association (WITS PSA). These tests have to be witnessed and signed off by other vendors of verified WITS Master Stations (for Field Device tests) or WITS Field Devices (for Master Station tests). More information on the WITS PSA test specification is available on the WITS web site: http://www.witsprotocol.org .
WITS Self-certified devices have only been tested by vendors using their own test equipment. These tests do not involve any Third Party.
ClearSCADA versions 71 and above are WITS verified for WITS 1.1.
