 +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.
