*2 The following instructions are not available with the same channel as for the G(P).BIDOUT instruction because they use a
communication protocol different from the one used by this instruction. In addition, if these are used with the same channel as for the
G(P).BIDOUT instruction, a communication protocol setting error (7FF2H) will occur.
