6. Screw-tighten the modules on the mounting rail. 7. You need to use a CPU with a SIMATIC Micro Memory Card. Insert this into the

receptacle. 8. You also need to install digital input and output modules to the right of the CPU. To do

this, repeat steps 1 to 6.

Units 3.2 2. Step: Wiring modules


3.2 2. Step: Wiring modules

WARNING You may come into contact with live wires that are connected to the power supply. Make sure that the S7-300 is completely disconnected before you start wiring.

Wiring the Power Supply and the CPU 1. Open the front panels of the power supply and the CPU. 2. Detach the strain relief clip from the power supply. 3. Strip the flexible power cable, crimp on the ferrules and connect them to the power

supply. (Blue to terminal M, black to terminal L1, protective conductor to terminal PE) 4. Screw the strain relief clamp in place. 5. Next, wire the power supply to the CPU. Use flexible cable with a conductor cross-section

of 1 mm2. Strip the ends to approx. 6 mm and crimp on the ferrules. Connect terminals L+ and M on the power supply to those on the CPU.

6. Check that the line voltage selector switch is set to the correct line voltage. The power supply is set at the factory to a line voltage of AC 230 V. To label a front connector, follow the steps outlined below: To change the voltage, remove the protective cap with a screwdriver, set the switch to the required line voltage and replace the protective cap.

Wiring the Digital Input and Output Modules 1. Open the front panels of the digital input and output modules. 2. Push front connectors into the DI and the DO until they snap into position. The front

connector still protrudes from the module in this wiring position, and is not yet connected to the module.

3. Cut around 10 wires (1mm2) to length (20 cm), and attach ferrules to the ends. 4. Wire the front connector for the digital input module as follows: – Terminal L+ to terminal L+ on the power supply; terminal M to terminal M on the power

supply – Terminal 3 to the first connection of button 1 – Terminal 4: with the first connection to button 2

Connect the two unassigned connections on buttons 1 and 2 to L+ on the power supply. 5. Wire the front connector for the digital output module as follows: – Terminal L+ to terminal L+ on the power supply – Terminal M to terminal M on the power supply 6. Lead the wires downwards out of the front connectors. 7. Press the release button on the front connector at the top of the module. At the same

time, push the front connector into the module until the release button snaps back into its initial position.

Note Please note: If you are using 40-pin front connectors, they must also be fixed using the fixing screw in the center of the front connector.

8. Close the front panels of the digital input and output modules and the power supply.

Units 3.3 3. Step: Commissioning the Hardware


3.3 3. Step: Commissioning the Hardware

Procedure 1. Use the PG cable to connect the programming device to the CPU. When using a cable

with PROFIBUS connectors, remember to switch on the integrated terminating resistors. Close the front panel cover of the CPU, then set the mode selector switch on the CPU to STOP.

2. Connect mains, then switch on the power supply module. The DC24V LED on the power supply is lit. All the LEDs on the CPU light up briefly; the SF-LED and the DC5V-LED stay lit. The STOP-LED then flashes slowly to indicate a CPU memory reset.

3. Depending on the type of CPU, you will need to insert either the SIMATIC Micro Memory Card or the backup battery into your CPU.

4. Perform a CPU memory reset: – Turn the mode switch to MRES. Hold it in this position until the STOP LED lights up

for the second time and then remains lit. Then release it. – You then have 3 seconds in which to turn the mode switch back to MRES. The STOP

LED begins to flash rapidly and the CPU performs a reset. You can now release the mode switch. The CPU has completed the memory reset when the STOP LED remains permanently lit again.

5. Start your programming device, then run SIMATIC Manager from your Windows Desktop. A window opens with SIMATIC Manager.

your project. The variable table for monitoring and modifying is displayed.




5. In the variable S_IMP_H of the VAT, select the count pulse source: – S_IMP_H = 0:

The pulse source is a programmed SW clock generator. Its frequency is adjustable via the T_PULSE variable. The clock is connected to the pulse input via a digital output.

– S_IMP_H = 1: Specify the count pulses by manually setting and resetting the S_IMP_T variable in the VAT.

6. You can perform the following tests:

Starting/stopping the counter: • Start the counter by setting the variables

SW_GATE (SFB parameter SW gate) and S_HWT (simulation of HW gate) in the VAT to 1 (logical AND).

• Stop the counter by resetting S_HWT or SW_GATE to zero.

You can monitor the actual counter value at the SFB output parameter COUNTVAL. You can view the status of the SW or HW gate in the variables STS_GATE or STS_STRT.

Loading a count value to the counter: • JOB_ID = 01 hex ("Write counter directly") • JOB_VAL = Count value (-231 to +231-1) • JOB_REQ = 1,

Job initiates at the positive edge

You can view the loaded count value at the SFB output parameter COUNTVAL. If no load error has occurred, the status at the output parameters is JOB_DONE = 1 and JOB_ERROR = 0.




Example: The "ZEn26_02_TF_____31xC_Cnt" project contains further samples you can use for orientation. You can customize all samples according to your personal applications.

3.6 6. Step: To insert CPU 317-2 PN/DP and assign it and IP address

Introduction Each Ethernet node is identified by a international unique address. This so-called MAC address is preset by the manufacturer and cannot be changed. In the following steps you will assign an IP address in the the Ethernet to this physical address.

Procedure 1. Select CPU-300 from the hardware catalog. Drag-and- drop the CPU 317 PN/DP to slot 2

of the mounting rail. The CPU 317-2 PN/DP is inserted in slot 2 and the properties dialog box of the PROFINET interface X2 is displayed.

2. Enter the IP address and the subnet mask. When working on a corporate network, contact your network administrator for information about this address.

3. If you setup a connection via router, you must also enter the address of the router. When working on a corporate network, contact your network administrator for information about this address.

4. Click "New", then assign a name for a new Industrial Ethernet subnet. Confirm your entries with "OK". Result: You created a new Industrial Ethernet subnet.

5. Click on the "OK" button. Result: The properties window of PROFINET interface X2 for CPU 317-2 PN/DP closes.

6. In HW-Config you can now also set the options of the PROFINET interface: In HW-Config, double click the PROFINET interface X for the CPU 317-2 PB/DP. If necessary, change to the "Options" tab. There you can customize the network settings. Default is "Automatic Settings", which is usually sufficient for error-free communication. Communication problems (connections fail, or frequent network errors, for example) may be caused by faulty settings, or by the automatic network settings. In this case, adjust your network settings to match you network configuration. Result: You can customize the network settings in HW-Config.



Save and compile your configuration: 1. Select the menu command "Station > Save and compile".

Result: The hardware configuration is compiled and saved. 2. Select the menu command "PLC > Download to module".

Result: The dialog box for the selection of the target group is displayed.

CPU 317-2 PN/DP is already selected as target module. 3. Confirm the dialog with "OK".

Result: The dialog box for the selection of the station address is displayed.

The CPU is not yet displayed in "stations reached".



4. Click "View". Result: The PG reads the MAC address and shows it on the dialog box.

5. Select the line with the MAC address of the CPU and confirm with "OK". Result: The message window opens.

6. Confirm the message with "Yes". Result: IP address is assigned to the CPU and the configuration is loaded.

7. Close HW-Config via the menu command "Station > Close" and answer question regarding saving with "Yes". Result: HW Config is closed. The CPU now appears in the station in SIMATIC Manager.
