Console Parameters

CHARON-AXP console line TTA0 (COM1COM2) has the following parameters:

ParameterTypeValue

communication

Text string

  • "ascii" - for connection to terminals  (default)

  • "binary" - for binary (packet) protocols, which are used mainly for communicating with PLCs

line

Identifier

This parameter is used to connect a particular serial line mapping interface to the controller.

Example:

set COM2 line=TTA0

All the values in this table are case insensitive.

ParameterTypeDescription
lineText string

A defined TTY port on host system:

SyntaxDescription
"/dev/tty<N>"Virtual serial lines
"/dev/ttyS<N>"Onboard serial lines
"/dev/ttyUSB<N>"Modem or USB serial lines adapters
"/dev/tty<XXX>"Proprietary (depending on a driver) devices such as DIGI or MOXA cards
baudNumeric

Forces the baud rate of the corresponding TTY port to a specified value.The variety of supported values depends on the underlying physical communication resource (TTY port). The most widely used values are: 300, 1200, 9600, 19200, 38400.

Example:

set OPA0 baud=38400
break_onText string

Specifies what byte sequences received over the physical serial line will trigger a HALT command.

This parameter works only for the console line.

Specify the following values: "Crtl-P", "Break" or "none" ("none" disables triggering a HALT condition).

Example:

set OPA0 break_on="Crtl-P"

The default value is "Break".

stop_onText string

Specifies what byte sequences received over the physical serial line will trigger a STOP condition. The STOP condition causes CHARON-AXP to exit.

Specify either “F6” or “none” ("none" disables triggering a STOP condition).

Example:

set OPA0 stop_on="F6"

The default value is "none".

Setting "F6" triggers the STOP condition upon receipt of the "<ESC>[17~" sequence. Terminals usually send these sequences by pressing the F6 button

logText string

A string specifying a file name to store the content of the console sessions or a directory where the log files for each individual session will be stored.

If an existing directory is specified, CHARON-AXP automatically enables creation of individual log files, one for each session using the same scheme as used for the generation of the rotating log files. If the "log" parameter is omitted, CHARON-AXP does not create a console log.

Examples:

set OPA0 log=”log.txt”

.

set OPA0 log=”/Charon/Logs”
Note

Only existing directory can be used as a value of the "log" parameter.

Example of mapping a console line to a host physical serial line:
