- Worldwide Industrial Telemetry Standards (WITS) is a suite of communications protocols designed for use within the public utility industry between components of a SCADA system. It was developed for communications between a WITS Master Station and its remotely connected WITS Field Devices (for example, Remote Telemetry Units). WITS maintains two protocols, WITS-DNP3 and WITS-IoT.
* WITS-DNP3 is a DNP3 protocol based protocol primarily used for larger 'always-on' utility assets. WITS-DNP3 is very well suited to traditional SCADA Telemetry control operations. WITS-DNP3 is based on the DNP3 protocol level2+, and uses DNP3’s generic protocol extension mechanism to define and provide the additional functionality required by water industry users. WITS-DNP3 provides Secure Authentication between Master and Field Device and uses device vendor supplied Configuration Applications for limited plug and play functions.
* WITS-IoT is a JSON based application layer protocol designed for very large numbers of smaller devices which may be online only for brief periods. WITS-IoT is well suited to the monitoring and logging of large numbers of infrastructure assets using battery powered devices over a wireless WAN. WITS-IoT provides for robust security using industry standard protocols, enjoys wide and easy availability of its protocol stack and adds full plug and play to WITS for the first time. While initially developed by and for the Water Industry, the WITS protocols are generic SCADA Communications protocols. The WITS functionality was originally defined in the mid 2000s by the UK water companies via a joint UK Water Industry / equipment vendors team. During 2011, ownership of the WITS protocol passed into the hands of the WITS Protocol Standards Association for future management and maintenance. (en)
