Pointer to a Boolean value of
the request attribute of the function
ReadPointValue. The function
ReadPointValue is called
after finishing the I/O tag initialization.
The function InitPoint (_InitPoint@12 in the Stdcall calling sequence) is
optional. A pointer to a PointPar structure with a definition of the I/O
tag parameters is the parameter of the function. The function is called at
starting of the process
D2000 KOM and later after a change of the I/O tag parameters in
D2000 CNF. If it is required to save the I/O tag address converted to a 32-bit
number into the list, the numerical address is to be saved into the parameter
FastAdr. If the address is not converted, the constant FastAdrNotUsed
is saved into the parameter FastAdr. For more info on addresses see
addresses of stations and I/O tags.
Request has been executed.
An error occurred (device does not communicate or is out of order, or
there is any error).
The function was ignored and the station status is not changed.
