Web and IT protocols for integration into IT infrastructures
The standardWeb/IT protocols enable Saia PCD® systems
to be universally integrated across all levels in existing IT
infrastructures with no additional outlay required.
An overview of Web/IT protocols supported by the automation server. Access is provided via
the Ethernet interface or via serial interfaces using the PPP protocol.
All Saia PCD® controllers have an integrated automation server with open standardWeb/IT interfaces. Saia PCD® are easy to inte-
grate into existing software infrastructures with no additional outlay required using the standard communication protocols.
Specific drivers or systems are not required. Standard tools such as web browsers, FTP clients and SNMP managers, etc., are used
to access the data in the PCD controllers.
DHCP: Dynamic Host Configuration Protocol
Protocols for automatically configuring the Ethernet communication. It is no longer necessary to enter the communication
parameters manually as they are assigned directly from a central server.
A DHCP client automatically receives the IP address, subnet mask, gateway and DNS address parameters on request.
The devices in the existing network are integrated automatically.
The devices are integrated in the existing network with no knowledge of the network parameters. Service personnel can also
exchange devices with no technical background or knowledge of the specific network data required.
