Modbus Remapping

Appendix I

Introduction

This appendix provides additional information about the Modbus Remapping feature.

Modbus Remapping Feature

The Modbus remapping feature allows a TCP Modbus Master to poll a Modbus slave device and have the IOLAN translate the UID to a different UID for the slave device. The Master UID has to be unique on the IOLAN. The Slave UID must be unique on each serial port. The translate rules are controlled by a file downloaded to the IOLAN.

The following procedure will allow you to use the Modbus remapping feature:

Create a configuration file

zThe file must be called "modbus_remap"

zOne translate rule per line

zThe fields on a line are separated by a comma

Line format for one UID is:

port,master_uid,slave_uid

zport: is the IOLAN port number that the slave is connected to

zmaster_uid: is the UID that the TCP Modbus Master uses

zslave_uid: is the UID that the Modbus slave uses

Line format for UID ranges is:

port,master_start-master_end,slave_start,slave_end

zport: is the IOLAN port number that the slave is connected to

zmaster_start: is the first master UID in the range

zmaster_end: is the last master UID in the range

zslave_start: is the first slave UID in the range

zslave_end: is the last slave UID in the range

Configuring the Modbus UID Translation Feature

1.On the serial port Modbus Gateway, configure Modbus slave. Configuration parameters such as “UID range” and UID Address Mode will be ignored in this mode of operation

DS1, TS2 specifications

Perle Systems TS2 and DS1 are advanced serial-to-Ethernet devices designed to facilitate seamless integration of serial devices with modern IP networks. These devices serve as crucial tools for businesses looking to enhance their communication capabilities while leveraging existing infrastructure.

One of the standout features of the Perle TS2 and DS1 is their ability to support multiple serial protocols including RS232, RS422, and RS485. This versatile support allows businesses to connect various legacy devices to their networks, ensuring that critical equipment can still communicate effectively in an increasingly digital landscape.

The TS2 model is particularly noted for its dual serial ports, enabling simultaneous communication with multiple devices. This capability is invaluable for applications requiring real-time data transmission, such as remote monitoring and automated control systems. The DS1 model, on the other hand, is designed for single-port use, making it an ideal solution for smaller-scale operations or specific single-device connections.

Both the TS2 and DS1 incorporate advanced features such as configuration through a web interface, which simplifies setup and management. Users can easily access device settings and monitor performance metrics remotely, enhancing operational efficiency. These devices also support various network protocols such as TCP/IP, UDP, and ICMP, ensuring compatibility with a wide range of network architectures.

In terms of security, Perle Systems prioritize user data protection. The TS2 and DS1 offer features including SSL encryption and SSH protection, providing an added layer of security for sensitive information transmitted over the network. This is particularly important for industries where data integrity and security are paramount, such as healthcare and finance.

Additionally, the rugged design of both devices ensures reliable performance even in harsh environments. With extended temperature ratings and robust housing, the TS2 and DS1 can operate in diverse conditions without compromising functionality.

To summarize, the Perle Systems TS2 and DS1 provide a reliable and flexible solution for connecting legacy serial devices to modern networks. With their support for multiple serial protocols, web-based management, robust security features, and rugged design, these devices cater to a variety of industries looking to modernize their communication infrastructure while maintaining existing equipment. Whether for large-scale operations or smaller implementations, the TS2 and DS1 equip businesses with the tools needed for effective serial communication in an IP-driven world.
