The CIO and DM number occupied by the PROFIBUS Slave Unit are set by the
machine number rotary switch on the front of the Unit.
Allocated CIO words (Start address CIO Area = 2000 + MACH No. x 10)
Allocated DM words (Start address DM Area = 20000 + MACH No. x 100):
• If two or more Units are set to an identical Machine number or if one Unit is set to areas of plu-
ral Machine numbers, the CPU Unit has a major fault level error, a duplicated Unit number
error, and stops operation. After correcting the Machine number setting, cycle the power to the
Controller.
• Be sure that no Machine numbers are duplicated.
To avoid duplication, when you set a PROFIBUS Slave Unit to the Machine number "n", set the
next Unit to the Machine number "n + 1".
