Multiple Analog Output Function Block (MAO)

Overview

The MAO block makes available to the I/O subsystem its eight input parameters IN_1/8.
This function block keeps the fault state features specified for the AO block. It includes option to hold the last value or a preset
value when in Fault State, individual preset values for each point, besides a delay time to go into the Fault State.
The actual mode will be LO only due to the resource block (SET_FSTATE parameter). If an input parameter has a bad status, that
parameter will be in Fault State, but the mode calculation of the block will not be affected.
The FSTATE_STATUS parameter shows that points are in Fault State.
The MAO block does not support back calculation, or the Cas mode.

Description

The Channel selects the input to be propagated in output at the connected transducer block.
Description / Range / Selections / Notes
Default string: "Input 7"
"********"
Each IN has an associated bit in order to
enable disable its use
Bit 7 = IN8 .....................Bit 0 = IN1
1: OFF (default)
2: ON
1: FAST (default)
2: SLOW
1: OFF (default)
2: ON
1: Disabled (default)
2: Enabled
3: Squawk once
Number of power cycle
Counter of how much time the device has been powered on expressed in days/hours/mins.
BLOCK
ALGORITHM
Bit x = 0 – Input not used/enabled
Bit x = 1 – Input used/enabled
Default = 00000001 = only IN1 enabled
When IN_SEQUENCE = ON, the MAO Channel must switch
to the next ENABLED Inputs evaluating the IN_ENABLED
bit corresponding to the channel number
When IN_SEQUENCE = ON, this parameter specify at which
rate chance the IN selection. Every 6 seconds when FAST
and 12 seconds when SLOW.
