PDFModbus TCP/IP Converters
Perle’s Modbus to TCP/IP converters (commonly referred to as Terminal Servers or Device Servers) connect Modbus based equipment to Ethernet.
- Communicate with multiple Modbus devices at the same time across a network
- Replace existing serial dial-up modem connections
- Use Modbus-Ethernet to connect serial PLCs to Ethernet
- Securely connect factory floor devices to your network
- Modbus TCP, ASCII, RTU and DF1 protocols
With the broadest choice of full featured Modbus to Ethernet solutions available, Perle has the right product to meet your RS232 to Ethernet or RS485 to Ethernet conversion project.
Converting Data from Modbus to Ethernet
Modbus data sent and received on serial ports on the Modbus to Ethernet adapter are encapsulated in Ethernet packets in a manner that best fits the type of data being transported. Learn more about Modbus Gateway Support on Perle IOLAN Serial to Ethernet Converters.
Perle's line of IOLAN Serial to Ethernet Converters are extremely flexible and can match your specific application requirements. Described below are just some of the possibilities.
Using RAW TCP Sockets
A raw TCP socket connection which can be initiated from the serial-Ethernet device or from the remote host/server. This can either be on a point to point or shared basis where a serial device can be shared amongst multiple devices. TCP sessions can be initiated either from the TCP server application or from the Perle IOLAN serial-Ethernet converter.
Using Raw UDP Sockets
For use with UDP based applications, Perle IOLANs can convert serial equipment data for transport across UDP packets either on a point to point basis or shared across multiple devices.
Console Management
For access to remote console ports on routers, switches,etc, Perle IOLAN’s enable administrators secure access to these RS232 ports via inband Reverse Telnet / SSH or out of band with dial-up modems. Perle IOLAN models with integrated modems are available.
Connect Serial-based Applications with a COM/TTY Port Driver
Serial ports can be connected to network servers or workstations running Perle's TruePort software operating as a virtual COM port. Sessions can be initiated either from the Perle IOLAN or from TruePort.
Serial Tunneling between two Serial Devices
Serial Tunneling enables you to establish a link across Ethernet to a serial port on another IOLAN. Both IOLAN serial ports must be configured for Serial Tunneling (typically one serial port is configured as a Tunnel Server and the other serial port as a Tunnel Client).
Virtual Modem
Enables the serial-Ethernet converter to simulate a modem connection. When connected to the IOLAN and initiates a modem connection, the IOLAN starts up a TCP connection to another IOLAN serial-Ethernet converter configured with a Virtual Modem serial port or to a host running a TCP application.
