This part can be written into and read as required. Its contents are not affected by

reading.

●

EVENt

The EVENt part indicates whether an event has occurred since the last reading, it is

the "memory" of the condition part. It only indicates events passed on by the transition

filters. It is permanently updated by the instrument. This part can only be read by the

user. Reading the register clears it. This part is often equated with the entire register.

●

ENABle

The ENABle part determines whether the associated EVENt bit contributes to the

sum bit (see below). Each bit of the EVENt part is "ANDed" with the associated

ENABle bit (symbol '&'). The results of all logical operations of this part are passed

on to the sum bit via an "OR" function (symbol '+').

ENABle bit = 0: the associated EVENt bit does not contribute to the sum bit

ENABle bit = 1: if the associated EVENt bit is "1", the sum bit is set to "1" as well.

This part can be written into and read by the user as required. Its contents are not

affected by reading.

Sum bit

The sum bit is obtained from the EVENt and ENABle part for each register. The result is

then entered into a bit of the CONDition part of the higher-order register.

The instrument automatically generates the sum bit for each register. Thus an event can

lead to a service request throughout all levels of the hierarchy.
