=head1 NAME Device-Modbus version 0.021 This distribution aims towards implementing Modbus communications in Perl. It should make 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. =head2 CURRENT STATUS Currently, the distribution is under development. You can find more information at http://www.7mavida.com/tag/Device::Modbus =head2 MILESTONES =over =item * Modbus TCP server =item * Modbus TCP client =item * Modbus RTU client =item * Modbus RTU server =item * Documentation =item * Shared over CPAN =back All of the above are now functional, I'd be greatful if you use this library and share any feedback. Please note that you need one of Device::Modbus::TCP or Device::Modbus::RTU. =head2 INSTALLATION To install this module type the following: perl Makefile.PL make make test make install =head2 DEPENDENCIES The 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. =head2 SEE ALSO The main documentation for the distribution is in L. Please see L and L for serial or TCP/IP based communications. In Perl, you can find other Modbus related distributions. I think the leading one would be L, 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 L. =head1 COPYRIGHT AND LICENCE Copyright (C) 2015-2016 by Julio Fraire This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.14.2 or, at your option, any later version of Perl 5 you may have available.
