Process-Dependent Operator Guidance Soft keys and Different actions are normally required or allowed in different operating screen hierarchies situations. To support changing requirements during process control, you can configure the following measures, which provide the operator with help depending on the situation and aims: screen-dependent soft keys and user-defined screen hierarchies.
Process-Dependent Operator Guidance 11.2 Self-Defined Screen Hierarchy Defining the The screen hierarchy can be adapted to system-specific requirements and be screen hierarchy modified either in part or in whole. Screens can be removed or added. Screens can be linked together in random order. The configuration, sequence of the link, inclusion in the screen directory and the relevant cross-jump destinations are defined during configuration with ProTool/Lite.
Process-Dependent Operator Guidance Example The OP3 is used to operate and monitor a system for producing and bottling different fruit juices. The system consists basically of a mixing unit and a bottling machine. Mixing unit The ingredients for the fruit juices are contained in three tanks. Depending on the juice that you wish to manufacture, ingredients are mixed in certain ratios.
Process-Dependent Operator Guidance 11.3 Evaluating Screen Numbers Application The screen number area is located on the PLC. The OP3 writes the number of the current screen to this area. If the PLC writes a screen number to the screen number area, the screen is opened on the OP3. You can configure operator guidance in this way.
Process-Dependent Operator Guidance Special Screens If the most significant bit has been set in the data word (=1), the screen number refers to a special screen. If the most significant bit has not been set (=0), the screen is a user-defined screen. The screen numbers of the special screens are listed in the table below.
Process-Dependent Operator Guidance 11.4 System Keyboard Assignment Application Create a data area for your system keyboard on the PLC. When you press a key, the corresponding bit is set in the keyboard assignment. The bit is set for as long as the corresponding key is pressed. Releasing the key resets the bit. By an evaluation of this area, the operator’s attention can be drawn, for example, by means of an event message to incorrect operation of a key.
Communication Types of The OP3 can be connected to SIMATIC S7 automation systems (PLCs) via connection two different network configurations. The network configuration depends on the CPU being used. The following two types of connection are possible: SIMATIC S7-200 Point-to-Point Interface (PPI) SIMATIC S7-300 Multi-Point Interface (MPI) (without CPU318)
Communication 12.1 Connecting to an S7-200 via the PPI Connection When you are connecting an OP3 to an S7-200, connect the OP3 to the S7-200’s PPI interface. In this particular instance, up to two S7-200s can be connected to the OP3. Similarly, you can connect several OP3s to a S7-200.
Communication Interface If data user areas are used that are area located in the interface area, you must create an interface area. You must configure a separate interface area for each S7 connected. Settings With ProTool, all settings with the exception of the interface area must be in ProTool performed by choosing PLC.
Communication Parameters The following parameters must be configured in the configuration software for a connection via the MPI: Address of the MPI address of the S7 module to which the OP3 communication is connected. The default address is 2. peer Expansion slot The number of the expansion slot containing the S7 module with which the OP3 exchanges data.
Communication 12.3 Interface Area for the SIMATIC S7 Purpose The interface area is required only if it is intended that the following functions be used or evaluated by the SIMATIC S7: Sychronize the date and time of the S7 and the OP3 Evaluate the connection ID and Detect OP3 start-up in the S7 program.
Communication 12.3.1 Control and Response Bits Purpose Three bytes are present in the interface area for the control and response bytes. Bytes n+0 and n+1 are used to synchronize the OP3 and the S7. Byte n+3 is not applicable to the OP3. Byte n+0: Byte n+0 is used by the OP3 to request the current time and the date from the Requesting...
Communication 12.3.3 Time and Date Purpose The current time and date are stored by the S7 program in bytes n+15 to n+17 and n+21 to n+24. This means that the OP3 can synchronize the time and date with the S7. Bytes Bytes n+15 to n+17 contain the current time of the S7 in BCD.
Communication Reading the You then transfer the S7 CPU system time to OP3. The FC6 uses the OP3 S7 system time requirement in the interface area to set the OP clock.

ESD Guidelines In this chapter This chapter describes the most important precautions which must be taken to avoid damage toe the electrostatically sensitive devices in the OP3. What Does ESD Mean? Electrostatically Nearly all modern modules incorporate highly integrated MOS devices and sensitive devices components.
ESD Guidelines Important Precautions against Charge Keep away from Most plastics are capable of carrying high charges and it is therefore plastics imperative that they not be placed near sensitive components. Grounding When handling electrostatically sensitive devices, make sure people, workplaces and packaging are properly grounded.
ESD Guidelines Shipping ESDs Conductive As a matter of policy, modules and components should be stored and shipped packing only in conductive packing – for example, metalized plastic boxes, tin cans. Should packing not be conductive, modules must be conductively wrapped before they are packed.
