DVC6200f Digital Valve Controller
MAI Function Block
February 2017
OUT_X status will be Bad if the transducer detects a problem with sensor associated with the channel.
Application Information
The intended use is for applications where it is necessary to convey DVC6200f measurements from a function.
The configuration of the MAI function block and its associated output channels depends on the specific application.
D CHANNEL [7]: Channel must always be set to 21.
The output parameters (OUT_1 to OUT_8 [8 through 15]) are set through the transducer block Instrument menu.
Each output has a channel assigned to it in MAI Channel Map (TB.MAI_CHANNEL_MAP [95]) in the transducer block.
For additional information, refer to table E‐30.
Block Errors
Table E‐28 lists conditions reported in the BLOCK_ERR [6] parameter.
Table E‐28. MAI BLOCK_ERR Conditions
Condition Number
Block Configuration Error: the selected channel carries a measurement that is incompatible with the engineering units selected
1
in XD_SCALE, the L_TYPE parameter is not configured, or WRITE_CHECK = 0.
7 Input failure/process variable had Bad status ‐ The hardware is bad, or a bad status is being simulated
14 Power Up - This condition exists after power up until the MAI function executes for the first time.
15 Out of Service ‐ The actual mode is Out of Service.

Corrective Action
Set target mode to something other than OOS
The actual mode of the Resource block is OOS. See
Resource Block Diagnostics for corrective action.
Block is not scheduled and therefore cannot execute to go
to Target Mode. Typically, BLOCK_ERR [6] will show
"Power‐Up" for all blocks that are not scheduled.
Schedule the block to execute.
FEATURES_SEL [18] in the resource block does not have
Alerts enabled. Enable the Alerts bit.
LIM_NOTIFY [32] in the resource block is not high
enough. Set equal to MAX_NOTIFY [31], also in the
resource block.
