Abstract: A drive controller comprises an evaluation unit to receive and evaluate a first item of feedback information from a motor connected to the drive controller, a control-signal block connected to secure inputs of the drive controller to receive condition control signals and to provide the condition control signals as input signals, a drive-signal block connected to the evaluation unit to calculate a first speed and/or a first position on the basis of the first item of feedback information on at least a first channel and to provide a first speed signal and/or a first position signal, a programmable logic unit connected to the control-signal block and the drive-signal block to realize the safety functions and the speed signal and/or the position signal to provide switch-off signals, and an output unit connected to the logic unit and to secure outputs of the drive controller to output switch-off signals on safety-switch-off paths.

Abstract: A method and corresponding system are described for monitoring a first node in a communications network by a second node, where the first node has a single-channel design and is designed to execute a safety-oriented application. The second node has a dual-channel design, and a safety protocol is used for a data transfer between the first and second node. The second node determines at each of two consecutive time points a time value based on an internal timer, and sends each determined time value to the first node. The first node in response to each receipt of the time values determines a further time value based on a further internal timer. The first node compares a difference between the two time values from the second node with a difference between the two further time values from the first node, and goes into an error state depending on the comparison.

Abstract translation: 描述了用于通过第二节点监视通信网络中的第一节点的方法和对应系统，其中第一节点具有单通道设计并被设计为执行面向安全的应用。 第二节点具有双通道设计，并且安全协议用于第一和第二节点之间的数据传输。 第二节点在两个连续时间点的每一个处确定基于内部定时器的时间值，并将每个确定的时间值发送到第一节点。 响应于每次接收时间值的第一节点基于另外的内部定时器确定另外的时间值。 第一节点将来自第二节点的两个时间值之间的差与来自第一节点的两个另外的时间值之间的差进行比较，并且根据比较而进入错误状态。
