The function block compares application signature and firmware version with a configured value. It also watches executions of sub-programs, actual cycle time of a cyclic task and provides interface for cross-checking of 2 controllers. Internally it tests integrity of variable memory and correctness of boolean and floating point operations.
This function block is intended to have significant influence on the physical movement of the crane and its load. The application of this function block requires accurate and correct input parameters in order to make its movement calculations valid and to avoid hazardous situations. If invalid or otherwise incorrect input information is provided by the application, the results may be undesirable.
