Posted October 27, 2026 at 9:02 am · in Packaging line 3: press, robot cell, inspection, packing and palletising on one drawing #5

How far can one drawing go? Our line is about three times this long.

Did an operators group like this for our packaging line. The Permissions tab on the member page caught a mistake for me, I had ticked attributes write and forgotten devices update, so they could change attributes but not rename a device.

Kevin, it works. Address byte with mark, data with space, PARMRK on the receive side. Indicators 1, 2 and 4 answered first try, number 3 wanted a 2 ms gap after the address, which I added. The children appeared in Hermetry on the first v1/gw/telemetry. Keeping Jason’s STM32 idea as plan B if the line people complain.

Once a second per indicator is plenty. David, the 9th bit tells every node “this byte is an address, wake up and check if it’s yours”. Data bytes have it at 0.

TCXO modules exist for exactly this if a probe still misbehaves.

Food plant automation guy here, glad there’s someone to ask about drawings. I’ll have questions about showing valve states soon.
