Hello everyone,
Recently I am dealing with one challenge. It is all about Transfer Time in Socket communication.
AOI from RA library is used for DATA Exchange PLC 1756 L71 and Inkjet Printer.
What is crucial in this application is transfer time, which has to be as short as possible.
In very fast period approx 30-40 boxes per minute Scale has to do update of new data which receives over socket comm.
Date Exchange sequence is working correctly but it has got one serious issue.
Transfer time I mean time from open socket to write and read action varies from 500ms - 2 seconds.
Setup for this application :
special 1756-EN2T is used only between PLC and Printer connected by one eth cable.
Task is running in period 20ms.
Does anyone have ideas how can it be improved or what might cause this variation ?
Is it something that I missed in it so far ?
I am running out of ideas.
Every advice appreciated!
Cheers!
Robert
