=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<Device::Modbus>. Please see L<Device::Modbus::RTU> and L<Device::Modbus::TCP> for serial or TCP/IP based communications. In Perl, you can find other Modbus related distributions. I think the leading one would be L<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 L<https://github.com/sourceperl>. =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.
