Format : SND Slot (Slot no. of Comm. Module) S(Source) Size (Data size to be sent) Result
Slot
a. It is hexadecimal.
b. Bit8 ~ F : Base expansion number (Local : 0, Expansion : 1~F)
c. Bit 4 ~ 7 : Communication type (CH.1 : 0, CH.2 : 1)
d. Bit 0 ~ 3 : Slot number
Source (Tx Data) : Starting address which has the frame data
Size : size(Byte) of frame data (Maximum 500Bytes)
Result : Device address which will have a communication result of sending frame data.
a. Bit 0 : When sending frame data is completed, bit 0 is 1 scan ON.
b. Bit 1 : When sending frame data is failed, bit 1 is always ON.
c. Bit 2 ~ 7 : OFF (Not used)
d. Bit 8 ~ F : Error Code (0 = No Error)
Example)
When X01 is ON, the SND instruction sends D100~D103(4word) to slave station through channel 1 of the serial module where is installed in slot number 2 in local base. The communication result is saved in M10.
