Chapter 5 Analog Modules
O_DISABLE_CONV
: This operate call tells ISaGRAF to disable the
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
<analog var>
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.
