WARNING
Verification of the input and output process data
After downloading the safety-related program to the TwinSAFE logic, the user must check that the input
and output process data of the TwinSAFE logic are plausible, within the valid value range and in the ex-
pected magnitude. This is especially true for analog signals, which are transmitted via e.g. PROFIsafe,
FSoE sensors, TwinSAFE SC terminals or external control systems to the TwinSAFE logic. It is particularly
important to check whether the device uses the Motorola or the Intel format or Big or Little Endian.
