Gurux.DLMS

Hello,

I want to implement the function like that, PLC module read meter load profile using LLS then push to HES by Data Notifiction. The maximum push data length is 512 Bytes. I would like using GuruxDLMS.c (ANSI C vision) on our communication module, but it is not clear how much RAM and code ROM is required to implement GuruxDLMS.c for this function. Could you help me? Thank you in advance.

Hi,

I can't say the exact numbers because I don't know what values you want to read from the meter. I can say that amount of the RAM is starting from 8 KB. Amount of the ROM is starting from 100 KB.

If you are not using ciphering the amounts are a little lower.

It's also easier if you can use malloc. It's possible to do without malloc, but it's a little bit harder to implement. You need to know what kind of data the meter is returning for each read and allocate memory for that.

Thanks a lot, Mikko.
Module just read meter 15mins Load Profile with 15 capture objects, we will try to use malloc.
