M172P* BACnet BBMD configuration and confirmation

obscuresc · ‎2024-06-13

Hi,

I'm looking at adding BBMD configuration settings to the HMI of a TM172PDG18R.

sysBACnet_BBMD does not provide too many details on how it works.

Do I have to continuously call 'sysBACnet_BBMD' as implied by 'BACnet Addons Lib User Guide v2.4'? Or is once sufficient per startup? Or once forever and then it sets EEPROM parameters in the background to start again?

Is calling it guaranteed to start the BBMD service? It returns 'TRUE' on every call, so it doesn't show if the service didn't start for any reason, such as if the provided inputs are invalid.

Thanks.

It can be called once, actually when it is called continously, it is really executed only when you change at least one function input (that's why we call it continously).

After a power cycle, you have to executed at least one time.

Hi,

it is called continously to allow to modify the settings runtime

@FedericoM if I don't change the settings, does it need to be called continuously? Also, will the service start automatically after a power cycle if it was set prior to the power cycle?
