Install the load current power supply (PM) on the installation rail. 2. Open the front cover and unplug the power connection plug. 3. Unplug the 4-pin connection plug and tighten the load current power supply (PM). 4. Insert the U-shaped connector into the back of the CPU. 5. Install the CPU on the installation rail and tighten it. 6. Insert the U-shaped connector into the back of the digital input module. 7. Connect the digital input module to the installation rail and tighten it. 8. Connect the digital output module to the installation rail and tighten it. Wiring rules for CPU Wiring steps for power connection plug 1. Use a suitable tool to pull out the connector cover. 2. Connect the power cord to the plug according to the wiring diagram. On the other side of the plug, there is information indicating the voltage that can be used after the plug is certified. According to the information on the back of the plug, select the corresponding voltage by inserting the coding component. 3. Close the cover. 4. Tighten the screw on the power connection plug. Connect the load current power supply (PM) to the CPU steps 1. Wire the 4-pin connector plug of the load current power supply (PM). 2. Connect the 4-pin connector plug to the 4-pin power connection plug of the CPU. Wiring steps for digital input module 1. Insert the front connector into the prewired position. At the prewired position, there is no electrical connection between the front connector and the module. 2. Secure the cable with a cable tie. 3. Connect the load voltage 24 V DC to terminals 20 (M) and 19 (L+). 4. Insert a potential circuit bridge between the two bottom terminals. Wiring steps for digital output module 1. Insert the front connector into the prewired position. 2. Supply DC 24 V power voltage to terminals 20 (M) and 19 (L+) from the digital input module through terminals 40 (M) and 39 (L+) on the digital input module. 3. Connect four potential circuit bridges. 4. Connect terminals 30 and 40, as well as 29 and 39. Wiring steps for the front connector 1. Connect each wire according to the wiring diagram on the inside of the terminal front cover and tighten them. 2. To eliminate tension, secure the cables with cable ties and tighten them. 3. Move the front connector from the prewired position to its final position. At this point, the electrical connection between the front connector and the module has been established. 4. Tip: The prewired front connector can be directly inserted, for example, for module replacement. Power-on first CPU startup steps 1. Insert the power connection plug of the load current power supply (PM). 2. Connect the power connection plug to the power source. 3. Insert an empty SIMATIC memory card into the CPU. 4. Switch the switch on the load power supply (PM) to the RUN position. The CPU will be started. The CPU starts and is in STOP mode. In this step, the IP address and subnet mask of the CPU will be set through the display. Steps: 1. Navigate to "Settings". 2. Select "Addresses". 3. Select the interface "X1 (IE/PN)". 4. Select the menu item "IP Addresses". 5. Set the IP address to 192.168.0.10. 6. Press the "Right" arrow key on the module. 7. Set the subnet mask to 255.255.255.0. 8. Press the "Down" arrow key on the module to select the menu item "Apply", and then click "OK" to confirm the settings. PART 06 Siemens PLC Wireless Communication
