PROGRAMMING
Toshiba's experience in industrial controls (robotics, process computers, etc .) has resulted in a very wide range of programming instructions available on the EX250/500. There are 15 basic instructions, contacts, coils, timers, counters, etc . for standard relay ladder logic . There are also 64 special functions such as word logic functions, compare functions, trigonometric functions, math functions, etc .
