Estimating the term…
A method for monitoring a communication connection between first and second subscribers, wherein a first processing program with a first cycle time is executed cyclically in the first subscriber, where in order to monitor the communication connection a first diagnostic unit with a first time counter is operated in the first subscriber, such that an arrival of a first telegram from the second subscriber starts the first time counter, an arrival of a second telegram from the second subscriber is monitored within a predefinable first monitoring time with the help of the first time counter, wherein a residual period is formed in the first diagnostic unit from the difference between the first monitoring time and the first time counter, and where a check is made to see whether the residual period is less than or equal to the first cycle time, and if so a monitoring signal is generated.
A method for monitoring a communication connection between a first subscriber and a second subscriber, a first processing program with a first cycle time being executed cyclically in the first subscriber, a first diagnostic unit with a first time counter being operated in the first subscriber to monitor the communication connection, such that an arrival of a first telegram from the second subscriber starts the first time counter, and an arrival of a second telegram from the second subscriber being monitored within a predefinable first monitoring time via the first time counter, the method comprising:
An automation controller comprising:
An output device configured to receive a telegram for the output of a process value, comprising:
