Actual refresh rate CP651 with ABB CodeSys ETH protocol
I have a CP651 which is communicating with several AC500 controllers. I am using the ABB Codesys ETH protocol for this. Does anyone know how the CP651 panel is calculating his actual refresh rate of his tags? Is this as fast as possible? And what is the consequence for the CPU load en RAM usage of the panel when there are a lot of tags with changing data?
This is what the manual says:
WARNING: Tags refresh rate is the maximum refresh rate. Actual refresh rate depends on: communication type (serial, fieldbus, Ethernet), protocol, amount of data exchanged.
