options for the protocol are: RS485 RTU
(default), RS485 ASCII, and RS232 ASCII.
Note: RS232 ASCII only supports one PLC or
Servo Drive.
Device:
The device specifies the physical port the PLC and Servo Drives are connected to.
Baud Rate:
The Baud Rate specifies the speed of communication on the COM port, measured in bps (bits per
second).
Data Bits:
The number of data bits for communications. Options are: 5, 6, 7, and 8 (default).
Stop Bits:
The number of data bits for communications. Options are: 0, 1 (default), 1.5, and 2.
Parity:
The parity for communications error checking. Options are: None, Odd, Even (default), Mark, Space.
Note: None, Mark, and Space options do not check for errors.
