Glossary Substitute value S7-300 backplane bus T Terminating resistance Time-out Transducer Transmission rate U User data Glossary-12 A value which is output to the process if a signal output module is faulty, or which is used in the user program instead of a process value if a signal input module is faulty. Substitute values can be defined by the user (e.g. ’hold last value’). A serial data bus which is used by the modules to communicate with one another and which supplies them with the necessary voltage. The connections between the modules are made with bus connectors. A resistance for power matching on the bus cable; terminating resistances are always required at the end of a cable or segment. The terminating resistances of the ET 200 are connected and disconnected in the bus connector. If an expected event does not occur within a specified period of time, this time is known as a “time-out.” In the HART protocol there are time-outs for the response of a slave to a message from the master, and for the pause after each transaction. Sensor (measuring transducer) or actuator (signal control element). A transducer can be implemented by a smart field device. The transmission rate is the speed at which data are transmitted and indicates the number of bits transmitted per second (transmission rate = bit rate). Transmission rates of 9.6 Kbps to 12 Mbps are possible for the ET 200. User data can be exchanged between a CPU and a signal module, a function module, or a communications processor via process image or via direct access. User data can be digital and analog input/output signals from signal modules or control and status information from function modules. I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04
