Energy accumulation and summation values not restored after reset or restart
Firmware for GRV-R7-I1VAPM-3
All versions prior to 3.5.0
Resolved In Version:
The energy accumulation values (provided through channels 13-17, 31-35, and 49-53) and the energy summation values (provided through channels 54-62) are not automatically saved to non-volatile memory every 30 seconds as specified in the data sheet. If the module resets or you restart it, those values will be set to 0.
Do both the following in your control program:
- At regular intervals, record the energy accumulation and summation values to persistent memory. For example, in PAC Control, save the values from those channels to persistent variables in a strategy. Another option is to write the values to a file that is saved to persistent memory.
- Write back the values to the associated channels after module startup. Write the values back to the channels as 64-bit integer milliwatt-hour values through the memory map at area 0xF02F8000 (64-bit Counters—Read/Write area). For instructions on how to write values to the channels through the memory map, see OptoMMP Protocol Guide, section "Reading and Writing Energy Values in GRV-IVAPM-3 & GRV-R7-I1VAPM-3" (form 1465).
