FIELD BUS COUPLER, SYSTEM, AND METHOD FOR CONFIGURING A FAILSAFE MODULE

The invention relates to a method for configuring a failsafe module (15) which is connected to a field bus coupler (11) of an industrial automation system via a sub-bus (12) in order to transmit security-relevant data of the module (15) via a field bus (3), having the following steps: - ascertaining the type of security protocol (5) which is compatible with the field bus (3) by means of the fieldbus coupler (11); and - transmitting configuration instructions to the at least one failsafe module (15) by means of the field bus coupler (11) in order to adjust the use of the ascertained security protocol (5) type in the module (15). The invention further relates to a field bus coupler (11) or a system consisting of a field bus coupler (11) and at least one failsafe module (15) which is designed to carry out the method. 本发明涉及种用于配置故障保险模块(15)的方法，该故障保险模块通过子总线(12)连接到工业自动化系统的现场总线耦合器(11)，从而通过现场总线(3)传输模块(15)的安全相关数据，所述方法包括以下步骤：通过现场总线耦合器(11)确定与现场总线(3)兼容的安全协议(5)的类型，以及通过现场总线耦合器(11)向至少个故障保险模块(15)发送配置指令，从而使模块(15)采用所确定类型的安全协议(5)
