the workshop
The objective of this workshop is to help delegates identify, prevent and fix common industrial
data communications problems focusing on the Modbus protocol. The focus is ‘outside the box’,
with the emphasis on practicals that go beyond the typical communications issues and theories.
The workshop’s aim is to provide delegates with the necessary toolkit of skills to solve industrial
data communication problems where Modbus is used.
Modbus industrial communications systems (based on RS-232/RS-485 and Ethernet) are being
installed throughout industry today, from connecting simple instruments to Programmable Logic
Controllers to PCs throughout the business part of the enterprise. Communications problems
range from simple wiring problems to intermittent transfer of protocol messages. Whilst the main
issues with the Modbus protocol will be covered in this workshop, a clear understanding of the
protocols and standards that transport Modbus protocol data units are required in order to
effectively work with Modbus.
The communications system on your plant underpins your entire operation. It is critical that you
have the knowledge and tools to quickly identify and fix problems as they occur, to ensure you
have a secure system. No compromise is possible here. This workshop distils all the tips and
tricks learnt with the benefit of many years of experience.
This workshop addresses the main issues of troubleshooting the industrial data communications
network of today, enabling you to walk onto your plant or facility and troubleshoot and fix
problems as quickly as possible. The focus of the course being the Modbus suite of protocols
and their associated standards.
practical sessions
This is a practical, hands-on workshop enabling you to work through practical exercises which
reinforce the concepts discussed. Practical sessions include:
• RS-232 (COM port) basics
• RS-232 point to point communications
• RS-485 basics
• Logging and protocol analysis on serial (RS-232/RS-485) communications system
• Modbus Serial operation: RTU mode
• Modbus Serial operation: ASCII mode
• Setting up a basic Ethernet network
• IP configuration
• Protocol analysis on Ethernet network
• Modbus/TCP
• Modbus (Serial) over IEEE802.11 wireless
• Installation and configuration of Modbus/TCP to serial communication gateway
To gain full value from this workshop, please bring your laptop/notebook computer.
