TH LINK for  Modbus TCP Protocol


Modbus TCP Network Diagnostics Independent from Controller and Control Room

The TH LINK for Modbus TCP diagnostics tool makes use of a controller-independent access to monitor Modbus networks. The diagnostic data is collected in networks comprising up to 254 nodes, and made available to users through the TH SCOPE software application. TH LINK ModbusTCP is easy to use and can be integrated without interfering with the operation of existing installations.

Independent Access to Modbus TCP Network

  • Controller-independent
  • Independent of configuration tools
  • Only one tool needed to monitor multiple IP subnetworks (up to 254 nodes, one or more controllers)

Designed for Installation without Interference with Plant Operation

  • Connection to free port in Modbus TCP network, also possible during operation of the plant
  • No need to install TAPs or use mirror ports
  • Highest security (separate accesses for control room level and plant level, no routing)
  • Easy integration into existing plants thanks to compact design

Powerful Data Collection Capabilities Optimized for Modbus TCP

  • Collection from Modbus TCP devices and other nodes (e.g. PCs or camera systems)
  • Combination of active and passive measurements
  • Limitation of network load

Optimized for Use by Maintenance Engineers

  • Suitable for network acceptance testing, continuous monitoring and troubleshooting
  • Easy and intuitive handling and operation
  • Fault identification with intelligent troubleshooting assistance
  • Seamless integration with TH SCOPE diagnostics software
  • Network detection and data collection
  • Alarm notification in case of fault
  • Basic monitoring, configuration
  • Integrated web server
