+It is possible to access the state of the output via gvarget commands from within the PLC process:
+<code>a= gvarget (0x400); // OUT0
+b= gvarget (0x407); // OUT7</code>
+Starting from 0x400 to represent OUT0, this is a hexadecimal system that is simple to convert to dotted decimals (through the likes of a simple reference site [[https://www.hexadecimaldictionary.com/hexadecimal/0x400/|here]]). Thus, for example, //gvarget(0x40d);// will return the state of Output #13.
