(Order Number: 6ES5 998-0UB22)
S5-100U System Manual (Order Number 6ES5 998-0UB23) has been completely revised:
• The format was adapted to the other system manuals in the SIMATIC S5 family.
• The contents were updated and reorganized.
Some of the functions of CPU 103 have been expanded:
• The default settings (default parameters) for DB1 have been integrated into CPU 103
version 8MA03. This feature makes it easier for you to use the internal CPU functions.
The following chapters were included or completely revised in the system manual:
- Chapter 9 "Integrated Blocks and Their Functions"
- Chapter 12 "Integral Real-Time Clock, for CPU 103 Version 8MA02 and Higher"
- Chapter 13 "Connecting the S5-100U to SINEC L1, for CPU 102 and Higher"
• The execution times of some operations have been reduced considerably, compared to the
"old" CPU 103. For the new execution times refer to the list of operations in Appendix A.
The S5-100U system has been expanded to include an additional module:
• The "Communications Module CP 521 BASIC" is described in section 15.10.2.
