*1: “SP” is space *2: The command argument n depends on the number of non-procedural command arguments. Return Value Precautions The length of the string of the no-stepping command that can be sent is 127 bytes (not including the delimiter). Set the parameters of $cmd_name and $cmd_arg[] so that the length of the string of the no-procedure command to be sent does not exceed 127 bytes.
Example The following example shows how to send the measurement command "MEASURE" to the Vision Sensor $cmd_name = "MEASURE" $cmd_arg[0] = "" $cmd_arg[1] = "" $cmd_arg[2] = "" $cmd_arg[3] = "" $cmd_arg[4] = "" cmd_arg_num = 0 CALL fhrunsendcmd(socket_no, cmd_arg_num, $cmd_name, $cmd_arg[], err_no) 53 If the number of no-protocol command arguments is out of the input range, an error is returned.
