AC800M CPU(PM861) module of high temperature alarm
Voted best answer
I understand the question is can our CPU send out an alarm for high temperature (of the CPU itself in System 800xA). Well from what we know, it cant do so for now. But there is a straight forward work around for that: a simple logic and a temperature transmitter will do the trick. 800xA is one of the best DCS in the market with an excellent Alarm Managment and Alarm Analysis Capabilities. This alarm too can be configured to how one may want it.
