How to Use Pilz Safety Relays?(Includes Wiring Diagram) A robust control system must first and foremost be a secure system—capable of ensuring the safety of individuals and equipment in the event of system failures or emergency shutdowns. When it comes to safety automation systems, the mention of Germany's Pilz company is inevitable. Pilz has been deeply rooted in the field of safety automation for decades, offering a range of safety products, including safety PLCs, safety switches, and safety relays. Notably, Pilz pioneered the development of the first safety relay (PNOZ) for emergency stops, gaining widespread recognition worldwide. Since then, PNOZ has become synonymous with safety relays. Today, Pilz offers a variety of PNOZ safety relay series, such as PNOZsigma, PNOZ X, PNOZcompact, PNOZelog, each with different models. In this article, we will take PNOZ X3 as an example to discuss the usage of safety relays for emergency stop buttons. The appearance of PNOZ X3 is depicted i...

Retain values in S7 1200 when power off

So how to set up the power-off data retention function for S7-1200? S7-1200 module (Photo: siemens.com/global) During operation, an unexpected power outage may occur, and the equipment operators hope that certain key data can be preserved in such cases to ensure the normal operation of subsequent production. The S7-1200 series PLC features a retained storage area that can be used to set power-off retained data. In this article, we will discuss how to set up the power-off data retention function for S7-1200. First, let's understand the composition of the internal storage area of the S7-1200 series PLC: The internal storage area of the S7-1200 includes the Load Memory, Work Memory, and Retain Memory. Load Memory: This is a non-volatile storage area, similar to a computer's hard disk. The Load Memory is used to store user project files (user programs, data, and configurations). When no memory card is inserted, users use STEP 7 software to download projects directly...
