Can you upload a copy of this EDS? ------------------------------ JeremyM ------------------------------

I saw this and immediately took 30 seconds to test - generic modules data structures are still arrays in v36. Phew. Did you import an "EDS/AOP" module by chance? ------------------------------ JeremyM ------------------------------

DPI-independent scaling is long overdue (but still welcome). That's some good news. ------------------------------ JeremyM ------------------------------

Thanks! I'll try carving some time out to test the client ability on my 5480. The KB would indicate that this process involves CIP object messaging on 5380/5580, so it could be possible, unless the class itself simply doesn't exist in 5480 firmware. ------------------------------ JeremyM - ...

It looks like the 5480 doesn't support being a OPC-UA server, not in Logix directly, anyway. Can it perform as an OPC-UA client? ------------------------------ JeremyM ------------------------------

To add to the good info Philip provided, the drive will not apply ineligible parameter changes until the drive is stopped, for example. As he highlighted, any parameter that's documented like that will not respond to a change until the requisite condition is met. AOP/ADC: This populates a hidden ...

Setting up a class 1 connection will depend on your Micro850 model. If you have a 2080-LC50E, you are good to go with a generic profile. If instead you have a 2080-LC50, you can only do class 3 messaging. ------------------------------ JeremyM ------------------------------

I'm glad I wasn't crazy in thinking this was a thing... a long time ago. I wonder what Rockwell's reasoning was for changing it. ------------------------------ JeremyM ------------------------------

To circle back, I came up with a compression method in the AOI to get all the parameters, their formula factors, and limits to exist within quite a small space. However... I was up late last night and studied the list of the returned 731 instances from the drive and realized that they all ...

Source[1,0,5,0] means the message is requesting 1 attribute, numbered 5. Size is 4 bytes. Source[2,0,5,0,13,0] means 2 attributes, numbered 5 and 13. Size is 6 bytes. ------------------------------ JeremyM ------------------------------

Your message configuration expects 34 bytes (Source Length) whereas your Source is only 4 bytes in size. ------------------------------ JeremyM ------------------------------

One suggestion I might add is to enable PTP (Time Sync) on all PLCs on a subnet, set a designated "grandmaster" PLC's Priority1 attribute to lower than the default 128, and write your WallClock updates to it alone. The change in time should propagate to all participants in PTP. ------------ ...

FWIW, how I pull in DPI attribute 20 in structured text. I avoid the strings for now - just focusing on the parameter itself. ------------------------------ JeremyM ------------------------------

Thanks Philip, I'm working with the PF525 with its 16-bit native parameters, though. With the PCCC read, I'm able to retrieve them in contiguous 16-bit payloads, COP them into a raw INT/UINT array locally, then assign them to the AOI's 32-bit PV output parameters using the DPI parameter object attributes. ...

I guess what I'm asking is whether Logix5K supports unofficially or through some Rockwell-internal method the use of pointers-to-void or pointers-to-type that can be assigned the address of another thing so I can generically iterate over a loosely homogenous structure's members (consisting of DINT or ...

Still wondering - is there an address-of or index-of operator or extended tag property that can be put to use? ------------------------------ JeremyM ------------------------------
