RKC CB100-CB900 driver's read schedule
Read schedule setting parameters are as follows :
1) STATION – STATION number set at controller(0~99).
2) Read Type – Input memory type. Refer to <Table 1>.
3) Read start address – Don't care.
4) Save Start Address for Communication Server – readed data saving start address of communication server.
5) Read Size – Fixed to 1.
