Bit in Word Description
Bit 0 The termination type configured for the port is not valid. Values
between 0 and 15 are the only ones valid. The module will use
type 0 (stream mode) for the port.
Bit 1 The baud rate entered for the port is not valid. The module will
use 9600 baud for the port.
Bit 2 The parity value entered is not valid. Values between 0 and 4
are accepted. The module has set the parity to a value of none
(0).
Bit 3 The number of data bits for the protocol is not valid. Values
between 5 and 8 are accepted. The module assumes a value
of 8 data bits.
Bit 4 The number of stop bits for the protocol is not valid. Values of 1
or 2 are accepted. The module assumes a value of 1 stop bit.
Bit 5 The handshake code for the port is not valid. The value
entered must be in the range of 0 to 3. The module assumes a
value of 0 (no handshaking).
Bit 6 The number of termination characters is not valid. The value
must be set between 1 and 12 when using the termination
character string to end a receive buffer. The module will not
terminate a buffer when using the termination character(s)
when this bit is set.
Bit 7 The number of characters for a packet is not valid. The value
must be set between 1 and 4096 when the packet size
termination option is used. The module will not use the packet
length termination option when this bit is set.
Bit 8 The message timeout value is set to zero. The module will not
use the message timeout termination option when this bit is
set.
Bit 9 The intercharacter delay value configured is set to zero. The
module will not use the intercharacter delay option when this
bit is set.
Bit 10 The write message timeout parameter is set to zero. The
module assumes a value of 5000 milliseconds.
Bit 11
Bit 12
Bit 13
Bit 14
Bit 15 Data is being received faster on the port than the ladder logic
can process the read blocks. Alter the configuration of the
module or the connected device. Receive data is being lost.
