MASTER-K S Series Loader communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – don't care. ( Fixed to 0 )
2) Read memory type – memory type of PLC. ( refer to <Table 1> )
PW, MW, LW, KW, FW, TW, CW, DW, SW : WORD unit reading,
PD, MD, LD, KD, FD, TD, CD, DD, SD : DWORD unit reading,
3) Read start address – reading start address(word or double word unit) in PLC memory. ( WORD unit reading = word unit address, DWORD = double word unit address )
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – word, double unit read size. ( WORD unit reading = word unit size, DWORD = double word unit size )

Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION don't care. ( Fixed to 0 )
3) ADDRESS write address in memory.
upper 3 digit = decimal unit Word address, lower 1 digit = 0 ~ F bit position.
4) Extra1 write memory type = P, M, L, K, F, T, C, D, S.
5) Extra2 don't care.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0011, EXTRA1 : M, EXTRA2 : 0
The setting parameter shown above is a control(On/Off) example for 1 word, 1(2nd) bit of M memory type.
Write example 2)
