FX2N-32DP-IF Profibus-DP Interface Unit
1.3.3

Configuration Rules

1) Total I/O points on the system ≤ 256 points
The 256 I/O maximum point includes all the categories below in addition to the I/O of the
extension module.
a) I/O points for the extension I/O units/blocks (including additional occupied points)
Refer to Table 1.7 for I/O point allocation for each extension unit/block.
b) I/O points for the special function units/blocks
A 32DP-IF can connect a Maximum of 8 special function units/blocks.
Refer to Table 1.7 for I/O point allocation for each special function unit/block.
c) I/O points for FX
2) Supply 24V DC (total internal and service power supply) and 5V DC to the extension I/O
blocks and special function units/blocks from the 32DP-IF or extension I/O unit.
Use the same configuration rules for the FX
48ET-DSS as applies to the FX
If 24V DC and/or 5V DC is insufficient for the extension I/O units/blocks and special function
units/blocks in this rule, the hardware configuration should include a powered extension I/O
unit.
For power consumption, refer to Table 1.5 ~ 1.14 and Figure 1.4 ~ 1.7. However, information
concerning Table 1.11 ~ 1.14 is same as Figure 1.4 ~1.7.
a) Check the loading on the 5V DC bus supply. Consumption values for special function
blocks can be found in Table 1.7. See the Table 1.4 for maximum available current.
b) Check the loading on the internal 24V DC supply for FX
Consumption values for these blocks can be found in Table 1.7. See the Table 1.5 for
maximum available current.
Use the same configuration limits for the FX
48ET-DSS as applies to the FX
c) Check the loading on the 24V DC service supply and internal 24V DC supply. Check the
number of expansion I/O in Figure 1.4 ~ 1.7 or Table 1.11 ~ 1.14. Find the residual
current.
When using the FX
retain the current consumption for those blocks' internal 24V DC supply. (Refer to Table
1.7)
Use the same configuration rules for the FX
48ET-DSS as applies to the FX
