Pulse instruction
16-bit instruction (5 steps)
32-bit instruction
Symbol:
S
1
：
Socket mode Word
S
2
：
Socket number Word
Explanation:
1. S
1
is 1 if users want to open the TCP socket, and S
1
is 0 if users want to open the UDP socket.
S
2
is the socket number.
2. The operand S
1
should be either 0 or 1, and the operand S
2
should be within the range between
1 and 8.
3. Before using this instruction, users need to use the instruction SOPEN to open the socket. If the
flag related to the connection’s being successful is ON, or the flag related to the connection’s
having been started is ON, this instruction can be used.
4. If the data is sent through the TCP socket, and no error occurs after the instruction is executed,
the data is sent, and the flag related to the data’s being sent is ON. If the data is sent
successfully, the flag related to the data’s having been sent is ON, and the flag related to the
data’s being sent is OFF. If an error occurs, the error flag is ON.
5. If the data is sent through the UDP socket, and no error occurs after the instruction is executed,
the flag related to the data’s having been sent is ON. If an error occurs, the error flag is ON.
6. Generally, the pulse instruction SSENDP is used.
