LD= Initial comparison contact. Active when the comparison (S1)=(S2) is true.
LD> Initial comparison contact. Active when the comparison (S1)> (S2) is true
LD< Initial comparison contact. Active when the comparison (S1)< (S2) is true
LD<> Initial comparison contact. Active when the comparison (S1)≠(S2) is true
LD<= Initial comparison contact. Active when the comparison (S1)≤(S2) is true
LD>= Initial comparison contact. Active when the comparison (S1)≥(S2) is true
AND= Seri ison contact. Active when parison (S1)=(S2)is eal compar the com tru .

OR= Parallel comparison contact. Active when the comparison (S1)=(S2) is true.
O Parallel compar Active when the com > (S2) is true. R> ison contact. parison (S1)
OR< Parallel comparison contact. Active when the comparison (S1)< (S2) is true.
OR Parallel compar Active when the com ≠(S2) is true. <> ison contact. parison (S1)
OR<= Parallel comparison contact. Active when the comparison (S1)≤(S2) is true.
OR Parallel comparison . Active when the com ≥(S2) is true. >= contact parison (S1)
