We have some sparkplug devices sending data to a MQTT distributor module.
If the values sent from the sparkplug device are the same as the current values in the MQTT engine. The timestamp in the Ignition tag system(MQTT-Engine) are not updating. Should not the timestamp update, even though the value is the same?
This gives a trend w/ gaps, alot of gaps. see the attached picture of two values always beeing sent at the same time. Here it can be seen that if the timestamp value has not been updated, a gap will occur.
I only want gaps to occure if the quality of the signal is something other than “Good”.
FYI, we use Ignition Historian for storing the values.
