    Problems can arise if a control is connected to an IP network, which contains mod- ules that do not have a SIGMATEK operating system. With such devices, Ethernet packets could be sent to the control with such a high frequency (i.e. broadcasts), that the high interrupt load could cause a real-time runtime error or runtime error.

    Buffer Battery The exchangeable buffer battery ensures that the clock time (RTC) and SRAM data of the HZS 774 are preserved in the absence of a supply voltage. A lithium battery is installed at the manufacturer. After delivery of the HZS 774 and storage of one year, the lifespan of the battery reaches 10 years, if it can be assumed that the module is continually in operation (connected to supply voltage).
