Request: CP340 serial MODBUS FC's

Post by monty_burns_007 » Tue Aug 01, 2006 3:16 pm

Hi,

Anyone here have a freeware or cured modbus library for the CP340 serial card ? Like the one on :
http://www.holgerbischoff.homepage.t-on ... odbus.html

The official modbus MASTER /SLAVE library from siemens comes with a stupid hardwaredongle which has to be plugged in the CP. The official modbus libary (loadable blocks) also doesn't support CP340, only CP341. :cry:
