For configuration rules, refer to section 1.3.3.
1) Check special function blocks.
a) Count special function blocks.
This 32DP-IF has 3 special function blocks connected (FX
This configuration is OK as the total number of blocks is less than 8.
b) Check the loading on the 5 V DC bus supply. Consumption values for special function

Total Consumption Values
This configuration is OK as the 5 V DC bus supply consumption value is less than 220 mA
(5 V DC bus supply capacity).
However, this system needs a supply of 455 mA from an external 24 V DC power supply, for
the special function blocks. In this case, the 32DP-IF can supply 250 mA for external 24 V
DC. See next page (check the loading on the 24 V DC service supply)
