Hello everyone! I am an amature programmer working with some small scale industrial control systems (PLC, data acquisition, I/O, Motion control, micro-controller etc). I was wondering if it is possible to develop a mod for HL2 that communicates with an external device via a COM (serial) port or UDP/IP. Can the non commercial (free) Source SDK provide a means to access DLL's or libraries that are not part of the Source SDK?
A simple example of what I would like to do: I setup a PLC or to read/write ASCII data from its serial port hooked to a PC. Two simple ASCII commands tell the PLC to either activate an output (or sequence) or return a data value. This would allow software to poll the device and when a specific condition is met, a command sent to activate the output or sequence. PLC stands for Programmable Logic Controller, basically an embedded computer with modular or fixed I/O (Digital, analog etc.) for automating any kind of system. I would like to create a virtual control panel HL2 mod. The user would spawn in a simple map consisting of a room with a virtual control panel that displays a data value from the PLC in the form of a dynamically updating texture and present the player with a switch to press that send an ASCII command via the COM port to the PLC. I know of an open source serial library for windows that can be included into any source file and allow one to communicate with a COM port without external DLL's. Is this possible? _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
