1 Task Description of the automation task Using the PSE200U module enables monitoring up to four 24 V load circuits electronically for overload or short-circuit. The PSE200U module is connected to a controlled 24 V power supply with up to 40 A output current, e.g. a 24 V power supply by SITOP. The PSE200U module divides the controlled output voltage (24 V DC) between four load circuits. The 24 V load circuits are connected to the outputs OUT 1 to OUT 4 and monitored by the electronic system of the PSE200U module. Load 1 is located in the 24 V load circuit of output OUT 1. The module detects, for example, if an overload or a short-circuit occurs in a load circuit. In the case of an overload or short-circuit, the appropriate outputs OUT 1 to OUT 4 are automatically switched off. The state output (S) of the PSE200U module supplies a signal that serially codes the state of the outputs OUT 1 to OUT 4. The following tasks must be solved in order for the status of the individual channels to be evaluated by the SIMATIC S7-300 CPU and displayed by the SIMATIC Panel: Reading the signal of the status output (S) of an S7-CPU. Evaluating the signal course of the status output (S) in the user program of the SIMATIC S7-300 CPU, in order to save the states of outputs OUT 1 to OUT 4 of the PSE200U module in the SIMATIC S7-300 CPU and provide it for the SIMATIC Panel. The S7-CPU must generate all massages on the state of outputs OUT 1 to OUT 4 for the SIMATIC Panel. Resetting the message and the PSE200U module at the SIMATIC Panel via remote reset.

The information available from the evaluation is displayed as message on a SIMATIC Panel. We will show you: Schematic layout how the PSE_DIAG (FB50) block is integrated in the user program of the S7-CPU how the states of outputs OUT 1 to OUT 4 of the PSE200U module are visualized on a SIMATIC Panel (TP900 Comfort Panel) a message procedure (control messages (PLC alarms)) The figure below shows a schematic illustration of the main components of this solution.

3 Basics on Control Messages (PLC Alarms) 3 Basics on Control Messages (PLC Alarms) Messages enable you to recognize processing errors within the automation systems, localize them exactly and remove them. This can considerably shorten the down-times of a plant. Before messages can be output, they need to be configured. The message system in WinCC V12 SP1 enables the display and recording of operating states and failures at a SIMATIC Panel, which are pending or occurring in a plant. The message system in WinCC V12 SP1 processes various alarm methods of the controller and the SIMATIC Panel. For the S7-300 CPUs only the control messages (PLC alarms) are used. Control messages (PLC alarms) are configured in STEP 7. These event-related messages are assigned to one respective block (FB). They are generated in the program editor. In the message editor you assign message texts and message attributes to the generated PLC alarms. Control messages (PLC alarms) are then further edited in WinCC V12 SP1. Note Detailed information on the configuration of control messages (PLC alarms) is available in chapter 5.2 and in the STEP 7 V12 SP1 manual (see \3\) Detailed information on working with messages in WinCC V12 SP1 is available in the WinCC V12 SP1 manual (see \4\).

The variables of the HMI interface are linked with WinCC basic objects and elements. Figure 4-4 4.4.1 Displaying the states To display the states of output OUT 1 to OUT 4 as well as the state of the PSE_DIAG (FB50) block on the SIMATIC Panel, the following variables of the HMI interface in the State of the outputs of the SITOP PSE200U screen are linked with WinCC basic objects and elements.

4 Functional Mechanisms of the Application 4.4 Visualization States of outputs OUT 1 to OUT 4 of the PSE200U module The individual bits of the CHANNEL_STATE variable contain the states of outputs OUT 1 to OUT 4 of the PSE200U module and are assigned in the text fields. This enables representing the states of outputs OUT 1 to OUT 4 via the background color of the text fields. Each text field shows the state of one output OUT 1 to OUT 4 of the PSE200U module. Each of the outputs OUT 1 to OUT 4 can take on state 0 or 1. The text fields are represented red or green independent of the state of output OUT 1 to OUT 4 (see Table 8-4). The following table shows which states of module PSE200U cause the outputs OUT 1 to OUT 4 to go to state 0 or 1. Table 4-8 State of PSE200U State of OUT 1 to OUT 4 Output enabled 1 Output current > rated current 1 Device starting up, supply voltage missing 0 Output was automatically disabled 0 Automatic disable can be reset 0 Output manually disabled 0 Output defective (internal fuse has tripped) 0 Device over temperature 0 Status of the PSE_DIAG (FB50) block The STATUS_SAVE variable contains the state of the PSE_DIAG (FB50) block and is assigned to an I/O field. 4.4.2 Controls the remote reset input (RST) of the PSE200U module The HMI_RESET variable is assigned to the RESET button. This enables you to set the variable to value 1 via the SIMATIC Panel and reset it to value 0 again. In the user program of the S7-CPU (OB1) the HMI_RESET variable is assigned to the digital RESET output (Q8.4). The digital output is connected with the remote reset input (RST) of the PSE200U module. When clicking the RESET button, the HMI_RESET variable is set to value 1, so the digital RESET output (Q8.4) and the remote reset input (RST) are controlled to trigger a reset of the PSE200U module. Outputs OUT 1 to OUT 4, which were automatically switched off due to a failure, e.g. overload or short-circuit, are automatically switched back on if the wait time of 20s has already elapsed. As soon as you release the RESET button, the HMI_RESET variable is reset to value 0. The digital RESET output (Q8.4) and the remote reset input (RST) are no longer controlled.
