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
.
