- Programming introduction
- Product Code description
What is a Saia PCD® Classic controller
The SaiaPCD® Classic controllers belong to the family of Programmable Logical Controllers (PLC) that are used to automate facilities and machines as well as in the building automation. The Saia PCD® Classic product range consists of a specific combination of operating system (firmware), CPUs, interface modules and software tools.
The flexibility and functionality range of the PCD controllers is much wider than the one of conventional PLCs and the long product life cycles as well as timeless design offer an optimal investment protection.
The extraordinary numerous communication possibilities complete the image of a very advantageous PLC.
The integrated S-Bus protocol (depending on the CPU type over serial line, TCP/IP, Profi-S-net and/or USB) allows connection(s) to a SCADA at a very low price level.
The term "Saia PCD® Classic"
The term "Classic" stands for the PCD (Process Control Device) types that are to be programmed by using the programming tool "PG5 Controls Suite". The PG5 Controls Suite contains the appropriate programming tools for all features of the Saia PCD® Classic controllers and is a product from Saia-Burgess Controls AG.
The Firmware (operating system of the PLC) running on the Classic PCDs is also developed by Saia-Burgess Controls AG.
Since all parts (Hardware, Programming tool PG5 and Firmware) needed to successfully run a PLC are developed and manufactured by SBC, these tools perfectly fit together.
