Text Parser
The Text Parser
for SAIA-PCD allows a SAIA-PCD system to receive a text string on a serial
line, a TCP or UDP port and to parse the text for values and keywords. The
library is designed to work with the Engiby Configurator which allows to define the syntax
rules in a MS-Excel file.
An Fbox allows
you also to ‘DEMUX’ the received values. It means that you can use a value or a
keyword of the message to switch the output that returns another value of the
telegram.
New: The driver can be used for several serial lines on the same PCD with
different syntax rules.
The Text Parser
cannot handle a communication protocol but only read a ASCII text send
spontaneously by a partner device.
The main
conditions are :
- The texts are sent
spontaneously.
- All sent texts have the same
structure. They can be decoded with the same rules.
- No BCC or checksum must be
checked (can exist but will be ignored).
- The texts are terminated by
<CR> or <LF>.
- No answer or acknowledgement
must be sent to the partner device.
- The evaluation of the
received and decoded values is not part of the driver.
Must be realized by the user in S-Fup or IL program.
