COMMAND | Description |
Base-Chan-Slot | Base: The number of the base where a computer link module is mounted is indicated. In case of expansion base, the number (1~16) of a corresponding base is indicated. In case of local one, the number is ‘0’.
Channel Mode: Ch 1(RS232:0) and Ch 2(RS422:1).
Slot No.: The number of the slot where a computer link module is mounted [Ex.] In case of local base, Slot 2, Channel 1(RS232) -> h0002 : RS-232C [Ex.] In case of expansion base (1), Slot 1, Channel 2(RS422) -> h0111 : RS-422 |
Addr | Address of the data sent |
Leng | Length of the data sent (BYTE), Decimal figure, Max. 500BYTE |
Result | The address where the result of sending is noticed is assigned. (X,Y,M,L,K,T,C,D,@D,Z)
Result Format : · Bit 0 : When sending completed, 1Scan ON. When failed, always ON. · Bit 1 : When sending failed, always ON. · Bit 2-7 : OFF · Bit 8-F : Error Code (0=No Error) |
