DONGEIECOS eRTU Inverter communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – 0 ~ 255 equipment address.
2) Read command – Command = MOD, ST1, ST2, ST3, ST4, ST5. (Refer to <Table 1>)
3) Read Start Address – Don't care.
4) Save Start Address for Communication Server – Saving start address of Communication Server.
5) Read Size – Size = Fix to 1.
