supported by all PLC types except FPM, FP1, FP3, FP5, FP10/10S |
All PLC types support TIME (32-bit) with the exception of FPM, FP1, FP3, FP5, FP10/10S which support TIME (16-bit).
Duration data must be delimited on the left by the prefix T# or TIME#.
The units of duration literals can be separated by the character _.
Time units, e.g. seconds, milliseconds etc., can be represented in upper- or lower-case letters.
"Overflow" of the most significant unit of a duration literal is permitted, e.g. the notation T#25h_15m.
The least significant time unit can be written in REAL notation without an exponent.
