Open Discussion / OMRON FINS protocol question
« on: May 21, 2018, 02:52:02 PM »
Hello All-
I have been trying to understand the exchange between AHMI and an Omron PLC.
I am using the 'y' beta version (Thanks Archie) but do not yet fully understand the packet structure and perhaps someone out there could help me in learning this.
Below is an abbreviated log file between a PC and an Omron unit runninf AHMI FINS serial communication:

Below is an abbreviated log file between a PC and an Omron unit runninf AHMI FINS serial communication:
Unit#- HDR - Resp - ICF - RSV - GCT - DNA – DA1 – DA2 - SNA – SA1 – SA2 - SID - Command Code, Text FCS - Terminator
@ X X F A X 8 0 0 0 0 2 X X X X X X 0 0 0 0 0 0 X X X X , xxx-xxx X X * CR
(How is this packet broken down? Where is SA2 and SID? Where is a FC command?)
