Introduction Introduction General information about the positioner The positioner is used to adjust and control pneumatic actuators. The controller operates electropneumatically with compressed air as an energy supply. The positioner together with the PROFIBUS PA communications inter- face are components in a digital process automation system. It commu- nicates with the master as a slave via the PROFIBUS PS field bus.

Introduction General information regarding PROFIBUS The PROFIBUS-PA(PA = Process Automation) is a variant of the PRO- FIBUS DP (DP = Decentral Peripheral) which is widely used in manufacturing engineering. The PROFIBUS (Process Field Bus) is an open communication sys- tem for automation engineering and thousands are used all over the world.
(GS*) files (available on the Internet at http://www.ad.siemens.de/csi_e/gsd). One or more class 2 masters can access the field devices acyclically in addition to the cyclic mode. With this communication type further infor- mation can be fetched from the devices or settings made in the de- vices.
Introduction 1.2.4 Profile Supplementary to the EN standard 50170, the PNO (PROFIBUS User- organisation) has defined the functionality of the individual field device types in a so-called profile description. This profile defines minimum functional requirements and optional extensions. The device-internal Device Management supplies all the basic information necessary for finding the profile parameters to the control system configuration tool.
Page 22
Introduction An additional terminating resistor T must be fitted at the far end of the bus for transmission-technical reasons. When using the recommended bus cable, the theoretically possible line length (sum of all line sections) is a maximum of 1900 mm. In addition, the voltage drop over the lines supplying the field devices must be taken into account in the planning.
Page 23
Introduction Before operation make sure that the positioner addresses of two or more field devices are set on the bus. So that the addresses are unique, each address must only be assigned once. In principle, an address range from 1 to 125 is possible. In its as-supplied state, address 126 is set.

Design and Functional Principle Design and Method of Operation The following chapter describes the mechanical and electrical design, the instrument components and method of operation of the positioner. Overview The electropneumatic positioner forms a control system in connection Introduction with an actuator. The current position of the positioner is detected by a servo potentiometer and fed back as actual value x.
Design and Functional Principle The limit value alarms are output by the alarm option module which can monitor and report the function of the positioner and the actuator addi- tionally through a fault message output. The value of the control differ- ence dependent on the travel time is monitored in automatic mode.
Design and Functional Principle 2.2.3 Pneumatic Connections The pneumatic connections are on the right hand side of the positioner (figure 2-3 and figure 2-4). Actuating pressure Y1 in single- and double-acting actuators Feedback shaft Supply air P Actuating pressure Y2 in double-acting actuators Exhaust air output E with silencer on the bottom of the instrument Figure 2-3 Pneumatic connection in normal version...
Page 29
Design and Functional Principle The exhaust air output E can be provided for supplying dry instrument air to the tapping chamber and spring chamber to prevent corrosion. Figure 2-5, page 27 shows the pneumatic connection variants for the different actuator types, the positioning acting and the safety position after power failure.
Design and Functional Principle 2.2.4 Mounting Kit The positioner can be mounted on almost all actuators with the ap- propriate mounting kit. 2.2.5 Purge air switching (not in the explosion-proof version) The purge air switch is accessible above the pneumatic terminal strip with the housing open (figure 2-6).
Design and Functional Principle Method of Operation The electropneumatic positioner forms a control circuit with the pneumatic actuator in which the actual value x is the position of the actuator bar in linear actuators or the position of the actuator shaft in rotary actuators and the command variable w is supplied digitally via the PROFIBUS.
Design and Functional Principle NOTE The exhaust air valve is always open when there is no current. Figure 2-8 Method of operation five-point switch State as supplied There are no mechanical mounting accessories on the controller in the state as supplied These must be ordered and installed according to the “operating instructions”...

Operation Optimization of the control data The data automatically determined during initialization for control qual- ity are optimized for short duration commands with small overshoots. In special cases (e.g. extremely small and specially quick actuators or when operating with boosters) it can however occur that these data need to be revised to achieve quick responses or heavy damping.

Care and Maintenance Functions/Operation via PROFIBUS PA System integration The positioner can be controlled and monitored by acyclic and cyclic data transmission by a control system (master). So that the positioner can be in communication as slave with the master, its address must be set up in advance.
Care and Maintenance With SIMATIC PDM the process device data can be displayed, adjusted, changed, compared, checked for plausibility administered and simulated In general, we recommend the following procedure: First of all read the current settings from the device, by initiating the action “Load to PG/PC”, Check the current settings, Check the required settings,...
Care and Maintenance To see the values displayed, open the ”Device” menu and open the ”Read maintenance information” sub-menu. Because there is so much information, these are divided amongst several registers: Maintenance information 1 and 2 here the initialization values such as zero point P0, end value P100, positioning times etc.
Care and Maintenance Only by confirming the register ”Reset counter” by pressing the ”Reset maintenance counter” key will the following maintenance counters be reset: Number of 100% strokes (STRKS) Number of changes of direction (CHDIR) Number of fault messages (\CNT) Number of alarms 1 and 2 (A1CNT / A2CNT) 5.2.1.6 Operation...
Page 125
Care and Maintenance NOTE Note that the positioner will respond after the transmission with the quality ”Bad” and the status ”value constant”. On leaving this target mode and if no further master sends a setpoint to the positioner, the positioner after the set monitoring period will adopt the parameterized fail safe value.
Page 126
Care and Maintenance Local Overlay (LO) To allow the drive to insist on maintaining the current position, the posi- tioner can be set using the PDM to ”Local Overlay”. In this mode the positioner valves will not be activated, although they can detect any leakage.
Care and Maintenance Simulation of Simulation functions are of assistance during commissioning pieces of readbacks equipment and positioner. Process values can be generated without output of real positional values. Equally the outputs from the alarm modules and the position value of the Iy module will not be affected by them.
Care and Maintenance To remove an positioner from the PROFIBUS line, its address should be restored to 126 using this function, so that in future it can be linked into this or another system if necessary. If a cyclic master is already in communication with the positioner, the address cannot be reset.
This means that it is pos- sible to optimise the quantity of data to be transmitted. The DMD files for all common devices are already stored in the Siemens control sys- tem, however they are also accessible over the Internet (www.ad.siemens.de/csi_e/gsd) and can be subsequently imported.

Care and Maintenance To communicate diagnostic information standard mechanisms within the PROFIBUS--DP can be called upon and an active report made to the class 1 master. PROFIBUS--DP provides a protocol for this to con- vey information that is of higher precedence than operating data to the class 1 master.

Technical Data Service and Maintenance The positioner is largely maintenance-free. The positioners are fitted with filters in the pneumatic connections as protection against coarse particles of dirt. This dirt will be deposited under pressure on to the filter and the filters may clog and impair the function of the positioner. In this case the filters can be cleaned as follows.
