1. Introduction
1.1 Product Outline and Features
The FX
3U
-32DP PROFIBUS-DP Interface Block (hereinafter called 32DP) enables users to integrate the
MELSEC FX
3G
/FX
3GC
*1 /FX
3U
/FX
3UC
*1 /FX5U *2 /FX5UC *2 PLC in any existing PROFIBUS-DP network (DP-V0/
DP-V1) as a DP-Slave. The 32DP links the FX
3G
/FX
3GC
*1 /FX
3U
/FX
3UC
*1 /FX5U *2 /FX5UC *2 PLC with
PROFIBUS-DP decentralized control tasks. The module connects the PLC system to the DP-Master in the
PROFIBUS-DP network for efficient and easy data exchange.
*1. An FX
2NC
-CNV-IF or FX
3UC
-1PS-5V is necessary to connect to the 32DP with the FX
3GC
/FX
3UC
Series PLC.
However, the 32DP cannot be connected to the FX
3UC
-32MT-LT(-2).
*2. An FX5-CNV-BUS or FX5-CNV-BUSC is necessary to connect to the 32DP with the FX5U/FX5UC
PLC.
1. Easy Connectivity to an existing PROFIBUS-DP Network
The 32DP Interface Module enables the FX
3G
/FX
3GC
*1 /FX
3U
/FX
3UC
*1 /FX5U *2 /FX5UC *2 PLC to fit into an
existing PROFIBUS-DP Network as a DP-Slave, while reducing the time and cost for users to build up a new
network system.
→
For the PROFIBUS-DP Network configuration, refer to Subsection 1.3.1
*1. An FX
2NC
-CNV-IF or FX
3UC
-1PS-5V is necessary to connect to the 32DP with the FX
3GC
/FX
3UC
Series PLC.
However, the 32DP cannot be connected to the FX
3UC
-32MT-LT(-2).
*2. An FX5-CNV-BUS or FX5-CNV-BUSC is necessary to connect to the 32DP with the FX5U/FX5UC
PLC.
2. Enhanced Data Exchange
The 32DP has enhanced the data exchange functionality in the following communication formats.
→
For details, refer to Chapter 5 and 6
• Cyclic Input/Output Data Communication - a maximum of 144 Bytes
• Acyclic Input/Output Data Communication - a maximum of 140 Bytes
• User-Diagnostic Messages
• Alarm(Status) Messages
3. Global Control
The 32DP supports SYNC / UNSYNC / FREEZE / UNFREEZE global controls.
→
For details, refer to Chapter 5
4. Flexible and Easy Network Setting
The 32DP enables a flexible and smooth integration with components on a new/existing PROFIBUS-DP
Network. The FX
3U
-32DP PROFIBUS Interface Block is fully applicable for the user-specific PROFIBUS-DP
Network.
→
For details, refer to Chapter 7 and 8
5. Various Transmission Speed Options
The 32DP supports the communication speeds, 9.6k, 19.2k, 45.45k, 93.75k, 187.5k, 500k, 1.5M, 3M, 6M and
12Mbps to fit into various kinds of networks. To connect the 32DP to a PROFIBUS-DP Network, use the
standard 9-pin D-SUB connector and shielded twisted-pair PROFIBUS cable complying with EN50170.
→
For wiring, refer to Chapter 4
→
For the transmission speed parameter, refer to Section 2.3 and 6.7
Note : INPUT/OUTPUT to where?
When this manual references INPUT/OUTPUT for communication data on the PROFIBUS-DP network, it
refers to data from the DP-Master's point of view. Therefore, CYCLIC INPUT DATA means THE CYCLIC
DATA STREAMING FROM DP-SLAVE TO DP-MASTER. On the other hand, ACYCLIC OUTPUT DATA, for
example, means THE ACYCLIC DATA STREAMING FROM DP-MASTER TO DP-SLAVE.
