Vendors provide counters, timers, indicators, text displays, and other types of off-the-shelf and custom controls for local and international markets, most of which communicate over a modbus network. As customers demanded more remote monitoring and control from vendors, they faced a significant problem - most of the control they provided was Modbus RTU instead of Modbus TCP. And a large part of their inventory is peer-to-peer RS232. Without a significant effort to replace these systems in many remote locations around the world, it is difficult to find a way to provide the remote monitoring that customers need.
Seek non-disruptive solutions.
A disruptive and costly workaround is eliminated: all industrial controls at the customer's site are distributedConfiguration software changesProvide services at remote sites. There is no need to change any existing industrial controls or computer programs while meeting the protocol requirements.
Profinet to ModBuscp makes it easy to communicate with the device without changing any existing industrial control or computer programs, while meeting all requirements for reliable communication with Modbus TCP and RTU protocols.
The solution uses Modbus RTU, Modbus TCP IP, Serial RS232, Ethernet, and wireless technologies.
For systems equipped with a Modbus master, the use of Profinet to ModBuscp in PLC slave-to-TCP client mode enables the PLC master to access the remote slaves as if they were on the same network. With three modes of operation, a user-friendly interface, multiple serial interfaces, and the ability to connect TCP clients to the RTU master, Profinet to ModButcp communication is the device of choice for Profinet to ModBuscp communication.
