E SR-750 UM
7-4 Ethernet Communication
Using the Ethernet communication, you can send data from the SR-750 Series, or
send operating instructions or change settings from the control device. This section
describes the basic specifications and functions of the SR-750 Series.
Basic Specifications
Ethernet port specifications
The SR-750 Series supports PoE (Power over Ethernet).
The pin arrangement of the Ethernet port on the SR-750 side is as follows:
• Pin arrangement of KEYENCE Ethernet cable
* When making a cable using the optional connector OP-87362, use a cable of
CAT5e or more.
Ethernet communication settings
SR-750 Series settings
Use the AutoID Network Navigator to set the following settings:
• IP address
• Subnet mask
• Default gateway
Ethernet default settings
The Ethernet default settings are as follows.
• IP address 192.168.100.100
• Subnet mask 255.255.255.0
• Default gateway 0.0.0.0
Reference
Pressing the TUNE button for at least 5 seconds sets the temporary IP
address setting mode.

Communication Function
Function Outline
Ethernet communication of the SR-750 Series is available with the following
functions:
Socket communication function
Sends read data of the SR-750 Series via socket communication.
Control the behavior of the SR-750 or change the settings via Ethernet by sending
operation and configuration commands to the command send/receive port.
Communication protocol: TCP
PLC link function (only for MELSEC and KV Series)
The PLC link is created via Ethernet.
Compatible PLCs are MELSEC Series and KV Series. "9-1 PLC Link (Page
85)"
Communication protocol: UDP
PROFINET
The SR-750 Series can make PROFINET communication.
For details, refer to "12-1 PROFINET (Page 109)".
Communication protocol: PROFINET
EtherNet/IP function
The SR-750 Series can be connected as an EtherNet/IP adaptor.
For details, refer to "11-1 EtherNet/IP (Page 94)"
Communication protocol: EtherNet/IP
FTP function
The SR-750 Series operates as an FTP server or an FTP client and can transfer
scanned image data or the setting file.
Communication protocol: FTP
Communication protocols for other functions
• Communication with Multimonitor: UDP
• Communication with FileView: FTP
• Master/Slave function: UDP
Port Numbers
This section describes the port numbers available on the SR-750 Series.
*1 9013, 9014, 9015, 5920, and 44818 cannot be set as they are reserved for the
reader system.
*2 When 9004 (initial value) is set, the command transmission/reception and the
data output occur at the same port. If you want to assign different ports to the
command transmission/reception and the data output, change the port number.
*3 Data port 2 performs client operations only.
