Question

For our applications a one-second data acquisition is used because we need the exact track of the vehicle.

I/Os are not needed every second. Most of them can be filtered out using the On Change operand and Event Only = Yes.
The user manual for FMM640/FMC640 doesn't mention how to configure On Delta Change but I found something in the FMB130 docs so I can use that setting, too.

However, there are values that would be useful to see in general, from time to time, even when there's only a small change. For the sake of an example, let's see PCB Temperature. I'd like to see its value in every few minutes, regardless of changes.

Hello

Of course, you can use the Delta change  operand for FMC/FMM 640

The following is additional information for all functions

and in this link for Delta Change

Repeating myself on the main question: "However, there are values that would be useful to see in general, from time to time, even when there's only a small change. For the sake of an example, let's see PCB Temperature. I'd like to see its value in every few minutes, regardless of changes."

In other words, there are I/Os whose values I'd like to have a constant supervision on even if they don't change. Setting Event Only to No would include values on records every second (triggered by position).

Hello

If none of the Operand meet your needs

Please do the development on your application / server and query the device via SMS / GPRS using the readio command with a set interval of time.

For AVLID 70 - PCB Temperature

readio 70

Hi,

Of course, I can query any values. ... Supposing the device connects the server. (Mass SMS is not a solution we'd like since it costs a lot.) This is what I'm doing for the "Event Only" I/Os anyway.

If we have a standby vehicle, e.g., if it doesn't move, there will be only a few records generated and seldom sent to the server = we can query values only once per several hours.

I guess we'll have to be satisfied with it.
