Table 3-6. Block Error
Conditions
Modes
The MAI Function Block supports three modes of operation as defined by the
MODE_BLK parameter:
Manual (Man)
The block output (OUT) may be set manually
Automatic (Auto)
OUT_1 to OUT_8 reflects the analog input measurement or the simulated
value when simulation is enabled.
Out of Service (OOS)
The block is not processed. PV is not updated and the OUT status is set to
Bad: Out of Service. The BLOCK_ERR parameter shows Out of Service.
In this mode, changes can be made to all configurable parameters. The
target mode of a block may be restricted to one or more of the supported
modes.
Number Name and Description
0 Other

incompatible with the engineering units selected in XD_SCALE, the L_TYPE
parameter is not configured, or WRITE_CHECK = zero.
2 Link Configuration Error
3 Simulate Active: Simulation is enabled and the block is using a simulated value in
its execution.
