Additional remark:
1.
If the value in S
, S
1
the error code in SR0 is 16#2003.
2.
If n exceeds the range, the instruction is not executed, SM0 is ON, and the error code in SR0
is 16#200B.
3.
If the device specified by S
is ON, and the error code in SR0 is 16#2003.
4.
If the device specified by S is not sufficient to contain the n pieces of data, the instruction is not
executed, SM0 is ON, and the error code in SR0 is 16#2003.
5.
If the function code specified by S
be the bit device. Otherwise, the operation error occurs, the instruction is not executed, and
the error code in SR0 is 16#2003.
6.
If the function code specified by S
to be the word device. Otherwise, the operation error occurs, the instruction is not executed,
and the error code in SR0 is 16#2003.
7.
If the communication command is 0x05 or 0x06, n does not work. The state or the data is
written into one bit device or one word device.
8.
If a flag related to the sending of the data is ON, and the corresponding flag related to the
connection's having been closed is not ON, the system will search for the flags which both are
ON to execute the instruction. If there are no flags which both are ON, the instruction is not
executed.
9.
During the connection, if the value in the high word of the remote IP address is 0, 127, or the
value larger than 225, the error occurs, and the corresponding error flag is ON, and the error
code is 16#6403.
10. During the connection, if the remote machine is disconnected, the error code is 16#6401. If
there is a connection timeout, the error code is 16#6402.
11. If the remote machine is disconnected when the command is sent, the error code is 16#6401.
If there is an ACK timeout, the error code is 16#6402.
12. If the function code is incorrect when the command is received, the error code is 16#6404. If
the length of the data is incorrect, the error code is 16#6405. If there is a response timeout, the
error code is 16#6402.
13. If the remote machine is disconnected when the connection is closed, the error code is
16#6401. If there is a connection timeout, the error code is 16#6402.
14. If users declare the operand S
15. When executing this instruction, if the network cable is not connected, SM1100 will be ON and
the error code is 16#600D.
