Technical support / Host Link Protocol Response
« on: May 13, 2013, 01:53:53 PM »
I have a Windows application that successfully communicates with an FMD88-10 using the Host Link Protocol.  I have noticed that when there is excessive traffic on the Internet connection to the PLC, the FMD88 will respond with HO* instead of whatever the proper response may be for the command that I have just sent.  I cannot find any reference to such a string in the user manual for the FMD88-10.  Is HO* some kind of error response?

Technical support / How to talk to PLC over Ethernet
« on: August 08, 2012, 11:17:21 AM »
I'm writing a Windows application to talk to several FMD-88's over Ethernet, but it is not clear from the user's guide what I should be sending to each unit.  Do I send commands as if I'm sending from another PLC?  This  doesn't seem to work.  I've used Wireshark to look at the network conversation from i-TRILOGI to an FMD-88 and the protocol looks different from what is in the user's guide.  Any help would be greatly appreciated.
