3. I/O Allocation in the FP1
The I/O addresses for the FP1 control unit, primary and secondary expansion units, and intelligent units (FP1
Transmitter Master Unit, FP1 I/O Link Unit) are assigned as follows.
Notes:
• X50 to X67 and Y50 to Y5F are allocated for the FP1 Transmitter Master Unit when it is used instead of
an expansion unit for FP1 C24, C40, C52 and C72 series, which have expansion units.
• The maximum number of expansion units that can be connected to the control unit is as follows:
- FP1 C14 and C16 series:
1 expansion unit (including FP1 Transmitter Master Unit)
- FP1 C24, C40, C56 and C72 series: 2 expansion units (including FP1 Transmitter Master Unit)
• Number of expandable units together:
- FP1 Transmitter Master Unit/FP1 I/O Link Unit: Max. 1 unit
