Good day.
Been having trouble with communicating with an I/O node.
We are using ethernet/ip and Allen Bradley system for this project, we are used to Profinet and siemens.
Currently, communication with main PLC is fine. we recieve and send data through the internal device without problems.
Also, at the tool of the robot there is a laser measurement device(sick), which is connected through an I/O module, and then to an I/O node (I call it an I/O node, i dont actually know what the correct word is) then from there to our ethernet/ip network.
However the device comes up as faulty configured in robotstudio/flexpendant. Sometimes after restart it throws the error 71500.
ive tried different EDS files, currently im using an EDS file ive downloaded directly from the node's webserver.
I can ping the I/O node with the assigned IP adress.
I can access the webserver of the node with the assigned IP adress.
I can see it inside RSlinx software, where it has the correct IP adress.
I've double checked with PLC guys to double check the IP adress list to check for double assigned.
Products:
I/O node: Allen-bradley 1734-aent/a
I/O module: Allen-bradley 1734-IE4C
Robot: ABB IRC5 6.12.04 /w relevant options 841-1, 997-3.
