Modbus is a serial communication protocol that was established in 1979. Since then, it has been widely used in industrial automation. LAN-RING switches and control units PLC IPLOG supports this standard.
The use of Modbus in industrial switches LAN-RING can be following:
Transparent transmission of Modbus data between RS485 ports
Modbus Support in Event Management of LAN-RING Switches
From June 2016, new firmwares were made available which extend the Event management and supports Modbus RTU and TCP. Typical applications are for example:
SLAVE Mode - PLC control via MODBUS protocol outputs of LAN-RING switch / monitoring its inputs.
MASTER Mode - Event management of LAN-RING switches communicate via MODBUS RTU or MODBUS TCP protocol with IO modules and sensors which are connected to the RS485 bus or are available on LAN networks.
Complex MODBUS solution for data collection, control and visualization of objects
We offer a comprehensive MODBUS solution that covers a wide range of requirements such as:
- Data collection from MODBUS sensors connected to RS485 bus switches or PLCs.
- Data processing in a PLC by a control program written in FBD, LD, ST or IL languages IEC 61131-3.
- Visualization of the system in IFTER-EQU software or in other software using SNMP or MODBUS.
