Glossary Configuration Connecting to common potential Device names Diagnostics Direct starter The systematic arrangement of the different ET 200S modules (setup). The opening of a new voltage group by a power module. This enables individual connection of the sensor and load supply to common potential. Before an IO device can be addressed by an IO controller, it must have a device name. This procedure was selected for PROFINET because names are easier to handle than complex IP addresses. Assignment of a device name for a concrete IO device can be compared with the setting of the PROFIBUS address for a DP slave. An IO device does not have a device name upon delivery. An IO device can only be addressed by an IO controller - i.e., for transferring configuration data (including the IP address) during startup or for user data exchange during cyclic operation - after it has been assigned a device name with the programming device/PC. Diagnostics involves the identification, localization, classification, display, and further evaluation of errors, faults, and messages. Diagnostics provides monitoring functions that run automatically while the system is in operation. This increases the availability of systems by reducing setup times and downtimes. A direct starter is a → motor starter that switches a motor on and off directly. It consists of a circuit breaker and a contactor. Distributed IO systems are input/output units which are not deployed in the central device, but which are set up decentrally at a greater distance from the CPU, e. g.: • ET 200M, ET 200X, ET 200L, ET 200S • DP/AS-I Link • Other DP slaves either from Siemens or other manufacturers The distributed IO systems are connected to the DP master by means of PROFIBUS DP. DP master A→ master that acts in compliance with the IEC 61784-1:2002 Ed1 CP 3/1 standard is termed DP master. ET 200S Glossary-2 Manual, 12/2005, A5E00514527-03
DP slave DP standard A → slave, which is operated with the PROFIBUS DB protocol and acts according to the Norm IEC 61784-1:2002 Ed1 CP 3/1, is known as a DP slave. Glossary DP standard is the bus protocol of the ET 200 distributed I/O system according to the IEC 61784-1:2002 Ed1 CP 3/1 standard. Electronic module Electronic modules make inputs and outputs available for process signals. There are digital and analog electronic modules. Equipotential Bonding Electrical connection (equipotential bonding conductor) that brings the conductive parts of electrical equipment and other conductive parts to the same or approximately the same potential in order to prevent troublesome or dangerous voltages arising between these parts. ET 200 The ET 200 distributed IO system with the PROFIBUS DP protocol enables distributed IO devices to be connected to a CPU or an appropriate DP master. ET 200 is distinguished by fast response times, since only few data (bytes) are transferred. ET 200 is based on the IEC 61784-1:2002 Ed1 CP 3/1 standard. The ET 200 works on the master/slave principle. A DP master can be for example the master switch-on system IM308-C or the CPU, 315-2 DP. DP slaves can be the distributed IO system ET 200M, ET 200X, ET 200L, ET 200S or DP slaves from Siemens or other manufacturers. Firmware update Updating the firmware of the interface module After (compatible) extensions of functions of improvements to performance, the interface module can be updated to the most recent firmware version. FREEZE This is a control command of the DP master to a group of DP slaves. When a DP slave receives the FREEZE control command, it freezes the current status of the inputs and transfers them cyclically to the DP master. After each new FREEZE control command, the DP slave freezes the status of the inputs again. The input data is not transferred from the DP slave to the DP master again cyclically until the DP master sends the UNFREEZE control command. ET 200S Manual, 12/2005, A5E00514527-03 Glossary-3
