Dear Friends,
There is a document named MODBUSD.pdf in the web http://www.industry.siemens.com:80/IT4I ... DBUS_D.pdf which is in German language ,and there is project or function block named FB240 or S7HOMOD3, described in the manual, I contact with IT4INDUSTRY but still there is no answer for me,and the question is, does anybody know where can i find this project file or does anybody has this file ? this file is a sample for communication of CP341 in MODBUS-RTU mode in PCS7-S7400-H system.
if any body has any idea about this topic please leave your commect in this post .
Thanks in Advance,
