2.6.7 The X-Function; 2.6.8 The F-Function; 2.6.9 The M-Function - Siemens SIMATIC S5 Manual

2.6.7 The X-Function

The X-function is the target function of the statement. It consists of the character "X", followed by
an optional sign and a number which specifies a distance in the units mm, 0.1 inches or degrees.
The number consists of five digits and three decimal places.
The maximum range of values is
X-99999,999 .. X+99999.999
Examples
X50, X50., X-.5, X+12345.678,...
If the decimal point is missing, it is assumed to beat the last place in the number,

2.6.8 The F-Function

The F-function describes one of the following:
the speed,
a dwell time or
the number of loop repetitions.
it consists of an 'F' and a maximum five digit, signless whole number.
As a speed, it indicates the units mm/min, 0,1 inches/rein or degrees/rein. The range of
values is then 1 .,. 65000.
As a dwell time, it specifies a multiple of 100 ms and can have values between 1 and
65000,
If the F-function is interpreted as a number of loop repetitions, the whole range of O to
65000 is possible. If O is specified, the loop is repeated continuously.

2.6.9 The M-Function

The M-function consists of the character 'M' and a two digit number. Permitted values are 0...99.
The significance of the number is only fixed for M02 and MOO.
An M-function is only output in conjunction with a traversing job (X-function or G74) or a
dwell time (G04) to the programmable controller and to the programmer. M-functions stand-
ing alone in a statement or alone with switchovers or offsets in a statement are ignored (ex-
ception: MOO). and IIQIoutput
