Word Description
Cfg_type 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.
Cfg_Baud Bit 1 The baud rate entered for the port is not valid. The module
will use
9600 baud for the port.
Cfg_Parity 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).
Cfg_DataBits 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.
Cfg_StopBits 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.
Cfg_Handshake 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).
Cfg_Rtermcount 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.
Cfg_RPacketLen 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.
Cfg_Rtimeout 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.
Cfg_Rdelay 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.
Cfg_Wtimeout Bit 10 The write message timeout parameter is set to zero. The
module assumes a value of 5000 milliseconds.
Cfg_Rswap Bit 11 Invalid receive swap code (0 or 1)
Cfg_WSwap Bit 12 Invalid transmit swap code (0 or 1)
Bit 13
Bit 14
Err_ROverflow 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.
