conversion of a particular channel of a connected

SM-DAD1 module. The syntax is as follows:

<analog var> := OPERATE(<iovar>, O_DISABLE_CONV, 0);

where

represents the analog return variable and can

be zero if the operate call is supported and the

correct

<iovar>

is passed or non-zero if an

error occurred.

<iovar>

is the variable name for the channel where the

operate call is to take effect.
