AI, AO, DI, DO Analog Input, Analog Output, Digital Input and Digital Output respectively. Byte A group of 8 bits. Each bit can be a 0 (off) or a 1 (on) allowing up to 256 combinations. Card A PCB (printed circuit board) and its connectors. A card is housed within a module. Comms Communications Current Sinking Current is supplied into the RTU’s IO terminal. G30 A double width module that includes a Power Supply Card, a Processor Card and may
include an IO card and a comms option card. Runs the Linux operating system and supports ISAGRAF.
IO Input, Output IP Internet Protocol. Used for ethernet communications. Port A physical connection or socket on an RTU used for communications Processor Module Processor module containing a CPU (central processing unit) Protocol Refers to the format of messages that may be passed to, from and through an RTU in
communication with local and remote devices. Communications may use one or more RTU ports. Examples of protocols used within telemetry include Kingfisher, Modbus and DNP3.
RTU Acronym for Remote Terminal Unit. Describes a group of processor, communication and IO modules that comprise a device for monitoring and control of hardware and devices in remote locations.
