In view of the problems with the CPU 945-7UA12/7UA22 ASIC, the              

application of intelligent I/O modules (IPs) has also been                  

restricted.                                                                 

                                                                            

To circumvent the problem, some of the standard FBs have been               

modified.                                                                   

                                                                            

Overview of possible applications of IPs, TDs and OPs with the              

above CPUS:
