*1 If (s1)+0 is set to "0: Without arrival check", receive data is not set. Set 0 in (s1)+0 in the following cases:

When a command that does not return a response message is used

When a response message is not referred to
*2 When “0” or “255” is specified to the fourth octet of the IP address of the target device, a send error occurs and the SP.SLMPSND
instruction is completed with an error.
In addition, the error code (C1CDH (SP.SLMPSND instruction message send error)) is stored in the completion status.
• When data of the error completion type (the 7th bit of (s1)+0) is set to "1" and "0", the operations are shown below.
