Could you please explain what does " fe , re , dec" means

if fe (Mixing_done)
then
feeder_state:=material_a_value+material_b_value;
reset (new_material_demand);
end_if;

(* calculating value feeder state *)

if re (forming)
then
dec (feeder_state);
end_if;

if feeder_state=2
then
set (new_material_demand);
end_if;

if feeder_state>2
then
set (feeder_full);
else
reset (feeder_full);
end_if;

Firstly I presume this is code from Structured Text (ST) in a PLC ? Which PLC are you using ?

They are all ST implementation of Ladder etc. so should be familiar if you program PLC's, most PLC programming packages will explain he usage in the help files.

It is Schneider, I am familiar with Siemens STL and ladder.
Yes, I use HELP but looking for pdf like siemens which explain ladder or fbd or stl
