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 interface are components in a digital process automation system. It communicates 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 PROFIBUS--DP (DP = Decentral Peripheral) which is widely used in manufacturing engineering. The PROFIBUS (Process Field Bus) is an open communication system for automation engineering and thousands are used all over the world.
(GS*) files. The files are available on the Internet at: www.siemens.com/sipartps2 Click on “More Info” and “--> Instructions and Manuals”. One or more class 2 masters can access the field devices acyclically in addition to the cyclic mode.
Introduction 1.2.4 Profile Supplementary to the EN standard 50170, the PNO (PROFIBUS Userorganisation) 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.

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.

Preparing for operation NOTE The positioner will be equipped at the factory and delivered complete with the necessary options at the customer’s request. Options modules may only be retrofitted by our service technicians. The positioner must be assembled -- especially in a moist environment -- in such a way as to rule out freezing of the positioner axle at low ambient temperature.
Page 51
Preparing for operation Figure 24 Favorable and unfavorable installation positions If conditions oblige you to operate the positioner in a unfavorable installation position, you can take additional precautionary measures to prevent penetration by water. NOTE Never clean the positioner with a high pressure water jet because the IP66 degree of protection is inadequate protection for this.
Preparing for operation Assembly of the screw--type gland with plastic hose Unscrew the sinter bronze silencer from the exhaust air opening on the underside of the housing. Screw the screw--type gland mentioned above into the exhaust air opening. Mount the above mentioned plastic hose on the screw--type gland and check the good fit.
Page 53
Preparing for operation Procedure After you have mounted the positioner and commissioned it completely, you can set the friction clutch torque as follows: Plug a conventional 4 mm wide screwdriver into a slot in the yellow wheel. Then turn the yellow wheel to the left with the screwdriver until it snaps in audibly.
Page 54
Preparing for operation External position Applications in which the measures described above are inadequate detection are also conceivable. This applies for instance with continuous and heavy vibration, increased or too low ambient temperatures and in the case of nuclear radiation.

Functions/operation via PROFIBUS PA 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.
Functions/operation via PROFIBUS PA 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,...

Functions/operation via PROFIBUS PA 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 138
Functions/operation via PROFIBUS PA Local Overlay (LO) To allow the drive to insist on maintaining the current position, the positioner 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.
Functions/operation via PROFIBUS PA 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.
Functions/operation via PROFIBUS PA 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 possible to optimise the quantity of data to be transmitted. The GSD files for all common devices are already stored in the Siemens control system, however they are also accessible over the Internet and can be subsequently imported.

Service and maintenance 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.
