The setting for the port settings determine if the default settings or user set-
tings will be used for port 1 and port 2. Be sure to use the same settings as
the communications port on the host computer connected via the Modbus-
RTU Slave System.
If the default port settings are specified, then the setting of bits 00 and 01 and
the baud rate in D32001 will be ignored.
The default settings used are as follows: Baud rate: 19,200 bps, start bits:
1 bit, data length: 8 bits, parity: even, and stop bits: 1 bit.
If user port settings are specified, set bits 00 and 01 and set the baud rate in
D32001.
