Blocks with cyan background are inputs for alarm calculation, pale yellow blocks are intermediate calculations and yellow one is final storage of alarm state. Red arrow indicate transfer of information with Passive Processing, black arrows with No Passive Processing.
The δ and ε are different parameters for CAEN HV, WIENER LV abd BIAS modules.
CAEN HV | WIENER LV | WIENER BIAS | |
δ | 0.5V | 0.1V | 0.5V |
ε | 0.01V | 0.01V | 0.01V |
Calcout record is recalculated and alarm state changed subsequently if one of inputs are changed achieved using posted monitors on input channels.
The difference with CAEN is that intead of Status we have Stat_string reported by hardware. In the CAEN haardware state reported is unique state. I.e. it could not be on the On and Ramping Up states simultaneously. In Winer/iSEG, the state could be combination of different states reported by bit pattern. We report an alarm if one of BAD states reported or channel is not on (bit0). Below is the list of bits reported by hardware (Note the bit8 is not used).
