  1. POUsing multiple variables across multiple functions in C#
    text
    copied!<p>I'm trying to write a program to interface with an I/O card. The hardware's provided documentation is in C# and I have never used C# before. So, pardon me if this question seems very basic or elementary.</p> <p>Using the manufacturer's functions calls for at least 3 variables per I/O pin and there are 55 pins. That means a lot of defined variables. As I am writing my code, I am finding that its very ugly. I am reusing snippets here and there that could easily be made a function. But making them a function, I lose the ability to access the multitude of variables. Is there some simple way to do this?</p> <p>Here is an shortened version of what I am currently working with. The missing pieces look the same. I'm using VS2012. Thanks in advance.</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Threading; /* Tool Changer Controller Program * In theory, this program will run the tool changer through a full cycle. * This includes: removing the current tool, * placing the current tool in its appropriate location on the carousel, * moving the carousel to the correct location of the new tool, * placing the new tool in the spindle so it is ready for use. */ namespace Tool_Changer { class Program { static void Main(string[] args) { // Create PoKeys55 device object PoKeysDevice_DLL.PoKeysDevice device = new PoKeysDevice_DLL.PoKeysDevice(); // Define all pins and correlate to correct pin // Pin: Pin #, Status: pass/fail returned, State: On/Off status // Swivel byte SwivelCCWA_Pin = 0; //Set* bool SwivelCCWA_Status = false; bool SwivelCCWA_State = false; byte SwivelCWA_Pin = 2; //Set* bool SwivelCWA_Status = false; bool SwivelCWA_State = false; // Telescope byte TeleExtA_Pin = 4; //Set* bool TeleExtA_Status = false; bool TeleExtA_State = false; byte TeleRetA_Pin = 6; //Set* bool TeleRetA_Status = false; bool TeleRetA_State = false; // Grabber byte GrabberOpen_Pin = 12; //Set* bool GrabberOpen_Status = false; bool GrabberOpen_State = false; byte ToolPresent_Pin = 13; //Get bool ToolPresent_Status = false; bool ToolPresent_State = false; // Begin Tool Change procedure.
