Rslogix copy int to two bytes how to#
I am trying to find someone on site who has Wireshark and knows how to use it so we can see the traffic from it trying to connect. My understanding from this diagram is that the Input size on the gateway should match the Input size on the PLC. Under license from The Rockwell Corporation, Hardy Instruments Inc. The strange thing is we left the I/O at the default 512 on both gateways successfully communicating with the one PLC. I realize that we have to straighten that out to get the mapping correct once we’re connected, but that shouldn’t affect the connection to the connection on the Enet I/P side in the meantime, should it?
Rslogix copy int to two bytes code#
The Profinet side was left at the default 512 while we tried the different configs. This is a simple RSLogix 5000 program designed to convert a integer which contains two ASCII characters read from a bar code reader to the first two characters in a String. So we tried 496 & 500 bytes and 124 & 125 in every combination, and couldn’t get it to work. The PLC is configured for 125 Dints in and 125 Dints out.
I have attached all of the different permutations of configurations we have tried. I have an engineer there directly connected. Unfortunately I am not on site and cannot connect with the gateways in question.
Thanks for the rapid response and clarification on the RSLogix version issue.
