preferred Caldan PLC hardware & software

PLC & Drives

the plc Hardware & software we use


The preferred PLC hardware and software in CALDAN controls is Siemens. Our control systems are based on Siemens components:

• we are using S7-300 series, also the new S7-1200, and 1500 series in our projects.

• The PLC programs is written in Step 7 or in the new Tia Portal v13.

• As communication media we are using Profibus, Profinet and the ASI bus for distributed I/O.

- This solution is reliable, cost saving and efficient, because a typical conveyor installation means long distances of wiring. Furthermore it gives smaller main cabinets when most of the I/O’s are handled as distributed I/O’s placed directly on the ASI bus.

• Safety. We use the integrated safety in Siemens PLC’s and components. This solution meet the requirement for a safe and functional conveyor controls system. Furthermore there is no need for a second safety PLC, which is expensive and also require space in the main cabinet. The safety level is SIL 2. CAT 3.

• If required CALDAN can also deliver controls system based on other brands than Siemens

List of preferred controls components:
• Siemens PLC
-  S7-300, S7-1200, S7-1500
- integrated Safety solution
• Siemens frequency converter
