This distribution aims towards implementing Modbus communications in Perl. It makes it possible to write Modbus TCP and RTU clients and servers. Please refer to Device::Modbus::RTU and Device::Modbus::TCP for the client and server implementations.
You will find examples and further discussions over my blog, at http://www.7mavida.com/tag/Device::Modbus
To install this module type the following:
perl Makefile.PL
make
make test
make installThe only requirement for the base Device::Modbus is Try::Tiny. The RTU and TCP variants have other requirements of their own, most notably Device::SerialPort for Device::Modbus::RTU and Net::Server for Modbus TCP.
The main documentation for the distribution is in Device::Modbus. Please see Device::Modbus::RTU and Device::Modbus::TCP for serial or TCP/IP based communications.
I am working on an asynchronous server for Modbus TCP. It is not yet ready for CPAN, but you can find it in GitHub, https://github.com/jfraire/AnyEvent-Modbus-Server.
In Perl, you can find other Modbus related distributions. I think the leading one would be Protocol::Modbus, by Cossimo, which implements Modbus TCP clients. While there is code for RTU clients, it is not as mature.
There are also some scripts that implement both a server and clients. A couple worth looking at is formed by MBclient and mbserved. The later is available in GitHub only and they were both written by the same author, l.lefebre https://github.com/sourceperl.
