Hello;
For a very basic explanation of the different Standard FBs, try Siemens' support webpage:

"http://www4.ad.siemens.de/csinfo/li...ID=4141141&objaction=csview&lang=en&siteid=cs":http://www4.ad.siemens.de/csinfo/li...ID=4141141&objaction=csview&lang=en&siteid=cs

and look at Document ID: 4141141

Here is part of the document:

The package contains the following functions:

ADD:32 32-bit binary adder
SUB:32 32-bit binary subtractor
MUL:32 32-bit binary multiplier
DIV:32 32-bit binary divider
RAD:16 16-bit binary root extractor
RAD:GP Floating point root extractor
REG:SCHB Shift register (bit)
REG:SCHW Shift register (word)
REG:FIFO Buffer
REG:LIFO Stack
COD:B8 Code conversion BCD to binary
COD:32 Code conversion binary to BCD
AE:464 Read in analog value from 6ES5 464
AE:460 Read in analog value from 6ES5 460/465
AE:463 Read in analog value from 6ES5 463
AE:466 Read in analog value from 6ES5 466
RLG:AA Output analog value
RETTEN Save scratch flags
LADEN Load scratch flags
DB-COPY Copying of data words between data blocks (DB/DX)
SST:UHR Clock
PER:ET Read and write for extended I/Os
The individual FBs for the programmable controllers are the
following:
S5-95U S5-100U S5-115U S5-135U S5-155U
CPU 103 CPU 941 CPU 922, CPU 946/47
to 944 928,928B

Hope this helps,
Daniel Chartier
