The Programmable Logic Controller (S7-1516) consists of a controller from the Siemens family. This powerful PLC comes with sixteen 24 V dc inputs, eight 4-20 mA inputs, eight 24 V dc output relays and eight 4-20 mA outputs hardwired to both banana jacks and terminal blocks on the module front panel. Banana jacks provide an easy and fast way to wire a setup, while terminal blocks allow students to wire their setup in a way much closer to what is commonly found in the industry.

The Siemens S7-1516 PLC supports two types of network communication: one PROFIBUS and three PROFINET ports.

The S7-1516 PLC is programmed using Siemens SIMANTIC STEP 7 Pro software in TIA Portal environnement (Model 46986) using any of four languages: Ladder (LAD), Function Block Diagram (FBD), Instruction List (IL). This module has ten switches that the instructor can use to insert faults.
