1. Segmented Modbus Serial Network with Flexible TCP Routing Mechanism
Traditionally, industrial engineers have to arrange the slave IDs of all the Modbus serial devices when using multiple ports of Modbus TCP gateways because it is restrained by only one TCP connection with a slave ID range from 1 to 254. However, this is becoming a nightmare for engineers due to the increasing complexity of field devices, especially when dealing with an extension project.
Newer Modbus Gateway with flexible TCP routing mechanism allows each serial port to be segmented by a dedicated TCP port or an virtual IP address, providing independent and flexible network connection to avoid slave ID conflicts.
2. Using Serial Redirector to Preserve Legacy Equipments
Enabling Ethernet-based remote access and monitoring systems is a growing trend, however, a local operation still has significant values in this transition period. With the Serial Redirector function in a Modbus Gateway, the local control devices such as HMI, which was connected to serial devices, can be kept operational while implementing a TCP-based SCADA network .
3. Ethernet Cascading Enables Daisy-Chain Connectivity for Easy Wiring
One of the major challenges in commissioning Ethernet network is to simplify the system architecture. With the Cascading feature, fewer Ethernet switches are needed on your network, and users also save on cabling costs as well as time and effort when setting up their Modbus TCP based system.
