Safety Guidelines

This manual contains notices you have to observe in order to ensure your personal safety, as well as to preventdamage to property. The notices referring to your personal safety are highlighted in the manual by a safety alertsymbol, notices referring only to property damage have no safety alert symbol. These notices shown below aregraded according to the degree of danger.

Dangerindicates that death or severe personal injury will result if proper precautions are not taken.Warningindicates that death or severe personal injury may result if proper precautions are not taken.Cautionwith a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.

Cautionwithout a safety alert symbol, indicates that property damage can result if proper precautions are not taken.

Noticeindicates that an unintended result or situation can occur if the corresponding information is not taken intoaccount.

If more than one degree of danger is present, the warning notice representing the highest degree of danger willbe used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating toproperty damage.

Learning units 33.1 1. Step: Installing the mounting rail and modulesRail installation sequence

From left to right: Power supply PS 307 - CPU 313C.The synopsis will provide you with an overview of the overall configuration.

Install and ground the mounting rail1. Screw on the mounting rail (screw size: M6) so that at least 40 mm space remains above

and below the rail.

When mounting it on a grounded metallic panel or on a grounded device mounting panelmade of steel sheet, make sure you have a low impedance connection between themounting rail and the mounting surface.

2. Connect the rail to the protective conductor. An M6 screw is provided on the rail for thispurpose.Minimum cross-section from the cable to the protective conductor: at least 10 mm2.

3.1 1. Step: Installing the mounting rail and modules


Installing modules on the mounting rail1. Hook the power supply module onto the rail, slide it until it reaches the grounding screw

of the rail and then screw it tight.2. Hook the CPU onto the rail (1),slide it along as far as the module on the left (2), and

swing it down into place (3).

3. Bolt the CPU tight, applying a torque of between 0.8 and 1.1 Nm.4. Insert the micro memory card into the CPU (4); this is essential for operation.

If you do not know the content of the micro memory card, erase it first on theprogramming device.

3.2 2 . Step: Wiring modules


3.2 2. Step: Wiring modules

WarningYou could touch live wires if the power supply module PS 307 is switched on or the supplycable of the power supply is connected to the mains supply.

Perform any wiring work on the S7-300 only when the power is off!

Wiring the power supply and the CPU1.

Open the front panel covers of the power supply module and CPU.

2. Unscrew the strain relief clamp on the power supply module.3. Remove the insulation from the power cord, attach the cable end sleeves (for stranded

conductors), and connect them to the power supply.

4. Screw the strain-relief assembly tight.5. Insert two short connecting cables between the power supply and the CPU and screw

them tight.

6. Check that the line voltage selector switch is set to the correct line voltage.The default line voltage setting for the power supply module is 230 VAC. To label a frontconnector, 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 theprotective cap.

Wiring the front connectors of the DI and DO1. Open the right front panel of the CPU 313C.2. Place the front connector into wiring position.

You do this by pushing a front connector into the CPU until it latches. In this position, thefront connector still protrudes from the CPU. In the wiring position a wired front connectorhas no contact with the module.

3. Remove 6 mm of the insulation from the ends of the wires that go into the frontconnector. Attach cable end sleeves to these ends.

4. Wire the front connector (DI side) as follows: Terminal 1: L+ of the power supply Terminal 3: Button 1 Terminal 4: Button 2 Terminal 20: M of the power supply

5. Wire the front connector (DO side) as follows: Terminals 21 and 31: L+ of the power supply Terminal 30: M of the power supply

3.3 3. Step: Commissioning hardware


6. Wire the free cable ends of the button with L+ of the power supply.7. Lead the wires downwards out of the front connector.8. Secure the front connector with the screws (this establishes contact with the module).9. Close the front panel covers of the power supply module and the front panel of the CPU.

3.3 3. Step: Commissioning hardwareProcedure

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

2. Connect the mains cable, then switch on the power supply module PS 307.The DC24VLED on the power supply is lit.

All the LEDs on the CPU light up briefly; the SFLED and the DC5VLED stay lit. TheSTOPLED then flashes slowly to indicate a CPU memory reset.

3. Perform a CPU memory reset: Turn the mode switch to MRES. Hold the mode selector at this position until the STOP

LED lights up for the second time and then remains lit (approx. 3 seconds). Thenrelease it.

You must press the mode switch back to MRESwithin 3 s. The STOPLED begins toflash rapidly and the CPU performs a reset. You can now release the mode switch.The CPU has completed the memory reset when the STOPLED remains permanentlylit again.

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

5. Select button 1.The LED of I124.1 lights up. No DO LED lights up.

6. Select button 2.The LED of I124.2 lights up. No DO LED lights up.

4. Carefully click on the horizontal line representing the current path.The line is highlighted.

5. On the toolbar, click twice on the --||-- icon (normally-open contact) and then once on the( ) icon (coil).

The icons are inserted into the current path.

6. Click on the red question mark for the left-hand normally- open contact in the currentpath.

The normally-open contact is highlighted and the question mark is replaced with a textinput box containing the cursor.

7. EnterI124.1and press Return.The left-hand normally-open contact is now called I124.1.

3. Set the CPU's mode switch to RUN.The STOPLED is switched off. The RUNLED starts to flash and then assumes acontinuous signal.

4. Press each of the buttons alternately.The LEDs of inputs I124.1 and I124.2 light up alternately.

The LED of output Q124.0 is not lit.

5. Press both buttons simultaneously.The LEDs of inputs I124.1 and I124.2 light up simultaneously.

The LED of output Q124.0 is lit. This would switch on a connected final controllingelement or indicator.
