3. Modbus RTU Protocol 

 
The Modbus protocol is developed by Modicon Inc., originally 
developed for Modicon controllers.  Detailed information can be 
found at 

http://www.modicon.com/techpubs/toc7.html

.  You can 

also visit 

http://www.modbus.org

 to find more valuable 

information. 
 
M-7000 series modules support the Modbus RTU protocol.  The 
communication Baud Rates range from 1200bps to 115200bps.  
The number of data bits is fixed to 8.  For M-7022 firmware 
version B102 and later, M-7024 firmware version B202 and later, 
M-7024L, M-7024R, M-7024U and M-7028, the parity can be 
none, even or odd.  For M-7022 other versions and M-7024 other 
versions, the parity and stop bits are fixed as no parity and 1 stop 
bit.  The following Modbus functions are supported.
