BAC_AC_ExtAFan_FC_01

Application

The template BAC_AC_ExtAFan_FC_01 is used for controlling a pressure-controlled outlet air fan.

The main tasks of the template are:

BAC_AC_ExtAFan_FC_01 1:

udiPltStp      : UDINT;
udiOpMod       : UDINT;

udiPltStp: Plant start sequence steps. The plant steps are generated in the system start program BAC_AC_StartT_01.

udiOpMod: Plant operation mode. The plant operation mode is determined in the mode selection programBAC_AC_OpMod_01.
