CONTROL DEVICE FOR CONTROLLING SAFETY-CRITICAL PROCESSES IN AN AUTOMATED PLANT AND METHOD FOR PARAMETERIZING THE CONTROL DEVICE

摘要

Safety-related functions in automation systems for controlling industrial production processes are achieved by providing a simple and safe parameterization of the safety-related apparatuses of such an automation plant. After a start signal sent by the communication master is received, all further activities for parameterization are controlled by a logic module.

主权项

1. A control device (1) with a communications network (4) for controlling safety-critical processes in an automated plant, wherein the communications network (4)
has an, in particular, non-safe communication master (2) for controlling the data flow on the communications network (4) and a plurality of network subscribers (12, 13, 14, 15, 16, 17, 18), wherein at least one subset of the network subscribers (12, 13, 14, 15, 16, 17, 18) are designed as safe network subscribers (12, 13, 14), and at least one safe logic module (5) as further network subscriber for controlling a safety-relevant application by means of a group of safety-related network subscribers (12, 13, 14), wherein the logic module (5) and the communication master (2) are set up for carrying out the following steps in order to parameterize the logic module (5): in response to the receipt of a start command transmitted via the communications network (4), the logic module (5) transmits a read request (45) to the communication master (2) via the communications network (4), in response to the receipt of the read request (45), the communication master (2) transmits parameterization data to the logic module (5).
