PPP: Point to Point Protocol
This is a protocol established along a communication
route from one point (location) to another. PPP
is a protocol that is mainly used to transport TCP/IP
protocols via a serial cable or modem connection.
In order to meet the greater security needs demanded
when dialling into company networks or systems with
critical tasks, CHAP (Challenge Authentication Protocol)
was introduced.
The user has access to the web and FTP server
via a Telekom interface (PSTN, ISDN, GSM/GPRS)
in the Saia PCD® controller. This also applies
to applications with more economical devices and
no Ethernet connection.
Standard

Authentication
PAP, CHAP and MS-CHAP

Intranet
The email function and integrated SMTP client (Simple Mail Transfer Protocol) can be used to send PCD device process and system
information to an email server. This enables alarm, service and status messages, log data or any form of process information to be sent
via email to a control centre or service personnel.
FBoxes
FBoxes are available for sending emails
using the application program. The email
function is configured (mail server, port
number, user and password, etc.) via
these FBoxes. It is also possible to send
file attachments (e. g. log data) of
up to 1 MByte.
