When you use an IA output, it will write to the entire word in the PLC that it 
is connected to. The PLC word must be under the control of one MASTER only. If 
the PLC must write to bits in this word, you must send the state to an IA input 
block and then connect the IA bit in the input parameter of the IA output block.
 
I do not believe that multiple MASTER's are permitted.
