1.2.1.1 Recommendation for designating variable types
In order to be able to recognize the type of variable in a program according to the name, it makes
sense to use the following designations, which are placed in front of the proper variable name and
separated from it by an underline stroke:
I_<Variablename> VAR_ INPUT
Q_<Variablename> VAR_OUTPUT
IQ_< Variablename> VAR_IN_OUT
R_<Variablename> VAR RETA IN
C_<Variablename> VAR CONSTANT
CR_<Variablename> VAR CONSTANT RETAIN
g_<Variablename> VAR_ GLOB AL
gR_<Variablename> VAR_GLOBAL RETAIN
gC_<Variablename> VAR_GLOBAL CONSTANT
gCR_<Variablename> VAR_GLOBAL CONSTANT RETAIN
Example
for a global array of type integer, that includes fixed setpoints (analog) for a speed setting:
g_anFixSetSpeedValue_a
