- Two lines or four lines
Baud rate [bps]
*1
1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 or 230400
Data length [bits]
*1
7 or 8
Parity
*1
Even, odd or none
Start bits [bits] Always 1
Stop bits [bits]
*1
1 or 2
Flow control
*1
None, RS/CS flow control or Xon/Xoff control None or Xon/Xoff control
Flow control target
*1
Send/receive, send only or receive only
Initial RS signal value
*1*2
*2. This is the value of the RS signal when the port enters the operational state or immediately after the port is restarted. The initial value is disabled when RS/CS flow
control is set. It is also disable for the NX-CIF105.
ON or OFF
Number of characters to deter-
mine the end
*1*3
*3. This setting is provided for communication protocols that assume the end of the data if data is not received for a specific period of time. For example, if the number
of characters to determine the end is set to 35, the end of the data will be assumed if data is not received for the time required to receive 3.5 characters.
0 to 10,000 (in increments of 0.1 character)
0: The end is not detected
Max. communication distance 15 m
*4
*4. If the baud rate is set to higher than 19,200 bps, refer to the manual for the remote communications device.
1200 m
*5
*5. The maximum total cable length for multidrop connections is 1200 m.
Connection configuration 1:1 1:N (max. value of N is 32)
You can change between two-wire
and four-wire connections
PDO data size [bytes]
*1
Inputs or outputs: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76 or 80
Transmission buffering enable/disable setting
