*1. Setting is possible in the Unit operation settings of the Support Software.
*2. You cannot set RS/CS flow control for the NX-CIF105.
*3. This is the value of the RS signal when the port enters the Opera
tional state or immediately after the port is
restarted. The initial value is disabled when RS/CS flow control is set. It is also disabled for the NX-CIF105.
*4. This setting is provided for communications 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.
*5. If the baud rate is set to higher than 19,200 bps, refer to the manual for the remote communications device.
*6. The maximum total cable length for multidrop connections is 1,200 m.
*7. This is the data size for one send or receive when the send or re
ceive data is divided before sending or receiv-
ing it. It has the following meaning for each system configuration.
CPU Unit connection: I/O data size
EtherCAT Coupler Unit connection: PDO data size
EtherNet/IP Coupler Unit connection: Ta
g size of tag data link
*8. The settings that are backed up are saved in memory in
the CPU Unit or Communications Coupler Unit. The
settings that are backed up are not saved in the CIF Unit.
