8.7.30 Comm 1 or 2 Message Interval
A read indicates the time interval in milliseconds between Comm 1 or 2 Message
Intervals. The maximum time interval indicated is 255.
8.7.31 Comm 2 Only Total Receive Errors
A read indicates the total MODBUS Comm 1 Only Receive Errors that occurred
in the slave device. The maximum count is 255 and then the counter will rollover
to zero and begin counting again.
8.7.32 Comm 1 Only SCI Errors
A read indicates the number of Comm 1 Only SCI (Serial Communications
Interface) Errors that occurred in the slave device. The maximum count is 255
and then the counter will rollover to zero and begin counting again.
8.7.33 Clear Comm 1 & 2 Errors
Writing a 1 to the bit activates the Clear Comm 1 & 2 Errors function which resets
all of the MODBUS Comm Error counters to zero. The function is active
momentarily and will reset automatically after being used.

8.7.34 Comm 2 Address
A read returns the Comm 2 address of the FL3100, FL3101. A write changes the
address to the requested address. The range of the address is 1 to 247 (01 to
F7 Hex). After the address has been changed to the slave unit, the MODBUS
communications will cease because the address has changed; therefore the
master will have to change its query address to the slave’s new address in order
to restart the communications.
EXCEPTION - If the EEPROM write error occurs, then the Exception Code 04
(Slave Device Failure) is returned.
NOTE - By grounding the RESET input during power-up cycle (approximately 10
seconds), the FL3100, FL3101 Address will default to 1.
8.7.35 Comm 2 Baud Rate
A read returns the Comm 2 baud rate of the FL3100, FL3101. A write changes
the baud rate to the requested baud rate. After the baud rate has been changed
to the addressed unit, the MODBUS communications will cease because the
baud rate has changed; therefore the master will have to change its baud rate to
the slave’s new baud rate in order to restart the communications.
