SIS configuration issue
Thread Content
What are the things to be mindful of when two security logic systems share a single processor?
Are the SIL levels of these two safety systems the same in terms of design? Has the number of IO points exceeded the limit allowed by the CPU? In simple terms, it’s just a SIS control system that is used to implement more control functions.
The two systems share one processor; previously, each system had its own processor.
As long as the score does not exceed the maximum allowed by the controller, it is fine
One set is in operation; I can also install the other set
Most security systems support offline installation, and it has nothing to do with the logic of how many devices are present in a single CPU.
If lower garments can affect the operating system, what about offline lower garments?
In theory, it’s possible to do it offline, but almost no one dares to take the risk of losing their job.
It is not recommended to install the SIS system offline
