Hi Folks
Im using a STRIDE I/O Link Master, part number SIOL-EI8B.
I got everything working via the provided example program and EDS file.
However my goal has not been to use with a PLC, but to do a direct connection with a FANUC robot.
My goal is to read RFID tag information directly into the robot to identify tooling and stations.
I have a scanner option on the robot, and planed ot just configure it similar to the PLC with identical connection size and Target/Originator parameters.
I have hit a dead end because the FANUC controller can not accept the 394 / 260 byte connection sizes that the EDS requires.
I am trying to figure out what I can change on the I/O link master to reduce its expects size for implicit connections, or if there is an explicit command that I can send to simply get the 4 bytes of process data on port X0 that I care about.
The cycle time or communication time is not important in this application.
I have read through the I/O Link documentation, the FANUC documentation and the implementation guide. Resources linked below.
Specifically I am looking to access the 4th byte of the Proccess Data.
I have succeeded with reading Parameter Data over the explicit messages instructions back into my PLC, but not the process data.
Per the IO-Link specification, Index 40 (0x0028) is a Read-Only element that holds the last valid Process Data Input value(s). This is an OPTIONAL implementation for IO-Link Devices. If your connected IO-Link Device supports this feature, then execute an Explicit Message targeting Index 40 (0x0028) and see if you can successfully capture the last valid Process Data Input value(s) of your connected IO-Link Device.
