Abstract
The disclosure relates to a method for testing the functionality of armatures, e.g., of safety armatures, in process control systems which are assigned a test device for implementing partial stroke testing and which are connected to a control device, which brings about actuation, in accordance with regulations, of the safety armature in an emergency. Prior to the start of the implementation of the partial stroke testing, a request signal is transmitted from the test device to the control device which is answered by the control device with an enable signal, the enable signal being issued as a function of the current process sequence at the armature.
