C.5 Multiple analog output block
The Multiple Analog Output Block (MAO_1400 to MAO_1700) accepts output values from field devices
and assigns them to specified I/O channels in order to make them available for the display.

Number
Parameter Description
1 ST_REV The revision level of the static data associated with the function block.
The revision value increments each time a static parameter value in the
block is changed.
2 TAG_DESC The user description of the intended application of the block.
3 STRATEGY The strategy field can be used to identify grouping of blocks. This data
is not checked or processed by the block.
4 ALERT_KEY The identification number of the plant unit. This information may be
used in the host for sorting alarms, etc.
5 MODE_BLK The actual, target, permitted, and normal modes of the block.
Target: The mode to “go to”
Actual: The mode the “block is currently in”
Permitted: Allowed modes that target may take on
Normal: Most common mode for target
6 BLOCK_ERR This parameter reflects the error status associated with the hardware
or software components associated with a block. It is a bit string, so
that multiple errors may be shown.
7 CHANNEL Defines the output that drives the field device.
8 IN_1 Numbered input parameter for multiple output function blocks
9 IN_2 Numbered input parameter for multiple output function blocks
10 IN_3 Numbered input parameter for multiple output function blocks
11 IN_4 Numbered input parameter for multiple output function blocks
12 IN_5 Numbered input parameter for multiple output function blocks
13 IN_6 Numbered input parameter for multiple output function blocks
14 IN_7 Numbered input parameter for multiple output function blocks
15 IN_8 Numbered input parameter for multiple output function blocks
16 MO_OPTS Options that the user may select to alter multiple output block
processing. In case a Fault State option is set, the 2230 will send a Field
Diagnostic alert.
17 FSTATE_TIME
18 FSTATE_VAL1 The preset analog value to use when failure occurs in IN_1. Ignored if
the “Fault state to value 1” in the MO_OPTS parameter is false.
19 FSTATE_VAL2 The preset analog value to use when failure occurs in IN_2. Ignored if
the “Fault state to value 2” in the MO_OPTS parameter is false.
20 FSTATE_VAL3 The preset analog value to use when failure occurs in IN_3. Ignored if
the “Fault state to value 3” in the MO_OPTS parameter is false.
21 FSTATE_VAL4 The preset analog value to use when failure occurs in IN_4. Ignored if
the “Fault state to value 4” in the MO_OPTS parameter is false.
