Analog Output (AO)
The analog output is the logical image, or memory map, of an analog control
command and describes its properties. Within the program, the Present Value
is made available to the block as a program value. The block converts the
program value and transfers the raw data to the physical I/O, where it is
converted into a 0…10 V signal, e.g., to drive a field device.
The following functions are integrated in the block:
● Evaluation of the priority array [PrioArr]
● Interruption of the output signal [OoServ]
● Conversion of the process value and feedback signal with slope [Slpe] and
● intercept [Icpt]
● Configurable switch type (Normal or Trigger)
● Limit value monitoring (OFFNORMAL alarm)
● Deviation monitoring
● Reliability monitoring [Rlb] (FAULT alarm)
● Change of state messages (events / system events)
● Process monitoring [StaFlg]
