Normal Serial Interface Section 6-2
6-2-1 Setting Communications Specifications
If the communications mode is set to Normal, the Controller can communicate
with an external device such as a personal computer through its serial inter-
face (with a RS-232C/RS-422 connection or Ethernet connection) using the
normal (no-protocol) format.
CHECK
Set the output data under the Normal data results output processing item.
• Setting Mode
Command inputs are not received.
• Monitor Mode
Command inputs are received, but the measurement results are not out-
put to external devices. Only the command execution result (OK or ER) is
output.
When a command is input to read a set value, the appropriate value will
be output.
• Run Mode
Command inputs are received and measurement results are output.
CHECK
After measurements have been made in Run Mode, the data up through
the last measurement will be output even if the mode is changed to another
mode. The data output will not be interrupted midway.

RS-232C and RS-422 Connections
1:1 Connection
In the following example, a measurement command is input and those results
are read.
Note When the Flow control is set to Xon/off and a response is not received from
the computer within the specified timeout time, a timeout error will occur
because the computer may be disconnected or malfunctioning. An error mes-
sage will be displayed on the Controller's screen and the parallel interface's
ERR signal will be turned ON.
