Abstract
This paper is focused on evaluation of dependability and safety parameters of PLC (Programmable Logic Controller). Achievement of requested level of these parameters is an application assumption for using PLC in control of safety critical processes. Evaluation of these parameters can be made on the base of suitable model and it can be influenced by system architecture when necessary.
