Device part of <Figure 1> input Device type(TCP/IP or UDP/IP), IP address of PLC(192.168.1.104), service port of TCP/IP(UDP/IP) protocol (fixed to 2004 for TCP, UDP = 2005 ),respectively, according to setting of PLC.
Also you can input enable of 'Error when PLC is slave' (0 : don't care, 1 : Error, default = 1), use of 'header data size error'(0 : don't use, 1 : use, default = 0), by using option part.
Note) Connectoin number of TCP/IP protocol and IP address of PLC, connection waiting time can set by using by using 'Frame Editor' of LSIS.
When the PLC status is 'slave' and lots of timeout occur, you set to 'Error when PLC is salve' mode = 0 (disable).
But when you using 'Line Duplex', you can set 'Error when PLC is salve' = 1( enable ). So you can transfer to 'Master' PLC'.
MASTER-K Ethernet 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,
PF, MF, LF, KF, FF, TF, CF, DF, SF : FLOAT low/high unit reading,
PF2, MF2, LF2, KF2, FF2, TF2, CF2, DF2, SF2 : FLOAT high/low unit reading.
3) Read start address – reading start address(word or double word unit) in PLC memory. ( WORD unit reading = word unit address, DWORD, FLOAT = 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. maximum 509 word, 254 double word. ( WORD unit reading = word unit size, DWORD, FLOAT = double word unit size )

You can set MASTER-K PLC by using write settings.
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.
5) Extra2 don't care.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0011, EXTRA1 : M, EXTRA2 : 0
