Programmable logic controllers (PLCs) that were vulnerable to the Stuxnet attack are still in use globally and rarely have security controls deployed — meaning they're still at risk. More than 10 ...

Siemens has issued a security alert about the company’s Simatic S7-1500 programmable logic controllers (PLCs) after security researchers at Positive Technologies reported “serious vulnerabilities” ...

This class discusses the basic concepts of programming Siemens PLCs. Linear and modular programming are both discussed, as well as different types of Siemens PLC engineering software and PLC program ...

Universal Robots (UR), a supplier of collaborative robots (cobots), has now integrated the Standard Robot Command Interface (SRCI) into its software. UR said it is among the first cobot vendors to ...

A Russian security researcher has unleashed a brute-force password-cracking tool that can capture passwords for Siemens S7 programmable logic controllers (PLC), which run machinery in power plants and ...

These small controllers deliver cost savings and many advantages over traditional methods of control. Seems like everything is getting smaller-cheaper-faster these days. So why not go smaller while ...

Security researchers have found a way to extract a global encryption key that was hardcoded in the CPUs of several Siemens programmable logic controller (PLC) product lines, allowing them to ...

When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...
