We have a control system (PLC) which reads the MPPT 100/20 parameters via VE. Direct 232 (Hex) protocol. Our system is comprised of:
- 1 x MPPT100/20
- 1 x BMV 712 Smart Bluetooth
- 1 x Smart Battery Sense
- These are connected and working smoothly together
We require to monitor the SOC, Battery Voltage and Temperature. We can read last two parameters (Temperature and Batt. Voltage) from the MPPT registers. So the smart Battery Sense fills the data registries in MPPT 100/20 and we can read them. Following the same approach, we wish to read the SOC from from MPPT registers (MPPT to perform be as our communication interface with PLC).
We don't want to implementing two VE. Direct 232 (Hex) protocol. in other words utilising one VE. direct connection to MPPT and capturing all the information that we can see on the mobile app.
P.S: We have tried and established a separate VE. Direct connection with BMV-712 and managed to read the SOC directly from there, but we can't have two serial connection to PLC.
Can anyone assist or provide some suggestion?
