Trying to link up a weighing software to control the closing and opening of a valve for a hopper. What it does is that when a weight target is keyed in to the system, the filling of a tanker is initiated until the target weight is achieved where the valve will then be shut. The process is done via a programmable logic controller.
Any suggestions on how this should be done using VFP on WinXP? The program needs to be fail safe as the valve control failure will result in dangerous chemical spillage.
Thanks in advance.
