Visualisation with S7 Controllers

System

The course teaches the essential functions of a Programmable Logic Controllers (PLC) and the visualisation of processes on an HMI touch panel. The trainer package for the Siemens PLC S7-1512C-1 PN contains assembly parts and accessories including the required PLC.

Learning objectives

• Creating programmes
• Learning logic and control functions
• Testing the programmes
• Setting up Profi-Net and Profi-Bus network connections
• Process visualisation in TIA

Teaching system

The training system consists of:

• SIMATIC S7-1500 KOMPAKT CPU, CPU 1512 C-1 PN, 32x DI, 32 DO, 5 AI, 2AO
• SIMATIC STEP 7 Professional
• ETHERNET cable
• Communication processor CP 1542-5 (only with catalogue number 773075)
• PLC base plate
• Touch panel HMI TP1500 Comfort

Description of the PLC base plate:

• 24 digital inputs of which 16 with push-button latching switch and 16 digital outputs are directly accessible via safety sockets (4 mm).
• 32 digital inputs and 32 digital outputs are accessible via 27-pin connectors with assignment for MCS.
• 2 analogue input channels and 2 analogue output channels are accessible via safety sockets (4 mm).
• Depending on the PLC, 5 analogue input channels and 4 analogue output channels are accessible via two 30-pin connectors.
• Profi-Net is connected directly to the CPU.
• The power supply unit is connected via an IEC plug with switch.
• The power supply unit is designed for an output of 156 W at 115 VAC / 230 VAC and 47-63 Hz. The mains voltage is preset.
• The control voltage is 24 V DC at max. 6.5 A.
