Subject: RECV bug in transport TCP layer
Date: Mon, 12 Nov 2012 09:36:13 +0000
To: "bug-Protocol-Modbus [...] rt.cpan.org" <bug-Protocol-Modbus [...] rt.cpan.org>
From: Martin Nørby Nielsen <mnni [...] dtu.dk>
Hey I found a data receive limit when I was trying to read more than 46 registers at once the limit should be 123 words. I debugged the problem to the receive line in \transport\TCP.pm line 71 $sock->recv(my $data, 100); please correct to: $sock->recv(my $data, 256); This should make it possible to receive 123 registers including the overhead : maximum according to the TCP modbus standard thanks for some sweet code I use it to interface with LAB PLC's kind regards Martin Nørby Nielsen Udviklingsingeniør Department of Energy Conversion and Storage Danmarks Tekniske Universitet [dtu] DTU Risø Campus, P.O.

Martin, thanks for your feedback. Sorry for the late answer, but 0.10 with the suggested change is on its way to CPAN.
