Block interlock conditions can be disabled with I_DISABLEn parameters. However, if the higher managed condition parameter I_HIGHER_MNGn is True, I_DISABLEn is ignored. When I_HIGHER_MNGn is False I_DISABLEn disables the interlock condition logic.
When I_DISABLEn is True, I_OUT_D_n is not set, regardless of the interlock condition's evaluation. However, the I_PRE_OUT_Dn parameter ignores the I_DISABLEn parameter. When I_DISABLEn is False, I_OUT_D_n and I_PRE_OUT_Dn have the same value. When I_HIGHER_MNGn is True, I_OUT_D_n remains equal to I_PRE_OUT_Dn, regardless of the value of I_DISABLEn.
I_DISABLE_ACT is the logical OR of the I_DISABLEn parameters. DISABLE_ACT is set when at least one condition of any type is disabled.
