Hi, good day to all:
I'll appreciate if anyone can tell me if you have or know of a virus from a lap top been inserted in a plc (CompaqLogix) and has affected the performance of the machine that it was controlling?.
Please elaborate just a little so I could understand the process. Thank you very much. baler.

PLC getting a virus happened only once so far, with Siemens S7-400 PLCs, in a nuclear uranium enriching plant in Iran.
It is not verified but it's considered USA & Israel secret services financed a team of highly skilled persons who were able to develop an extremely complex and convoluted way to infect a PLC with a virus.


Most likely your PLC doesn't have a virus, otherwise something really shady is happening at your place.
