Your system hardware must be in control of your process at all times, regardless of system load. To assure this, it is now possible to Step-Up your hardware, by replacing it with more powerful units. This also extends the expected life time of the system parts.
Combined with Automation Sentinel, there is an even greater price incentive: It is the most cost efficient way of increasing system hardware performance, compared to any other way of acquiring brand new certified parts.
