FX2N-32DP-IF Profibus-DP Interface Unit |
Introduction 1 |
1.Introduction
The FX2N-32DP-IF Profibus-DP Interface Unit (hereafter called “32DP-IF”) can be used to connect extension blocks/units and special function blocks of FX2N/FX0N series directly to an existing Profibus-DP network.
The 32DP-IF provides an intelligent slave function for decentralized control applications. Digital and analog data from a Profibus-DP master CPU (hereafter called “DP-master”) can be sent and received to/from any of the supported I/O blocks and special function blocks.
1.1Features of the 32DP-IF
Using the 32DP-IF extension blocks, units, special function blocks of FX2N/FX0N series can exchange data with any DP-master.
•Up to 256 I/O points and/or up to 8 special function blocks can be connected to the 32DP-IF. However, adjust total control I/O points to 256 or less. See section 1.3.
•The slave address of the 32DP-IF is adjusted by DIP switches. See chapter 5.
•The 32DP-IF can be connected to a Profibus-DP network by a standard 9-pin D-SUB connector and a shielded twisted pair cable complying with EN50170. Optional glassfiber adapters are supported by the 32DP-IF and are available from other vendors.
See chapter 2.
•An FX-20P-E or personal computer can be used to monitor the devices of the 32DP-IF or to set parameter for special function blocks connected to the 32DP-IF. For operating instructions of the FX-20P-E or personal computer, refer to their respective operation manuals and to section 1.3.1. For device numbers and explanation, refer to Chapter 4. For parameter of 32DP-IF, refer to chapter 6 and appendix B.

FX2N-32DP-IF Profibus-DP Interface Unit |
Introduction 1 |
1.3.3Configuration Rules
1)Special function blocks: Max. 8 blocks per 32DP-IF.
Check the loading on the 5 V DC bus supply. Consumption values for special function blocks can be found in Table 1.7. For maximum available current see the Table 1.6.
2)Maximum I/O points: 256 or less.
3)Check the loading on the 24 V DC service supply. Look up the number of expansion I/O in Figure 1.4. Find the residual current. This can then be used to power sensors etc.
4)Check total exchanged data length in DP-master, this number might be limited by the DPmaster unit. Data length is exchanged between the 32DP-IF and a DP-master in every cycle.
For the data length of connected extension units/blocks, refer to Table 1.3.
However, the maximum amount of data that can be exchanged with the 32DP-IF is 200 byte inputs and 200 byte outputs.

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 (FX2N-4AD × 1, FX2N-4DA × 2). 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 blocks can be found in Table 1.7. For maximum available current see the Table 1.6.

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)

3)Check the total allowable exchanged data length for each input data and output data in the DP-master, because this number might be limited by the DP-master unit.
Maximum exchanged data length of 32DP-IF can be found in Table 3.3. For the data length of connected extension units/blocks, refer to Table 1.3.
