• When transferring data, it should be observed that the lengths for the
transmitters and receivers communicating with one another coincide.
Otherwise data transfer is "transparent", i. e. the CSH11 transfers all
data unchecked.
• Word (2 bytes) and double word(4 bytes) quantities are transferred in
the Little-Endian format, i. e. the least significant byte at the beginning
and then the most significant byte. When communicating with devices
which deposit data in the Big-Endian format, then the user must adapt
appropriately (e. g. for SIMADYN D using the SWB... conversion
blocks).
Communications via SINEC H1 layer 7 is configured at address
connections AT and AR.
• The application associations are configured using the NML
configuring tool.
Further information
on the configuring tool NML, refer to the User documentation
"SINEC NML - CP141x, CP1470".
• When accessing defined complex STF variables (arrays, structures)
defined in SIMADYN D, it is only permissible to access complete
variables; partial access is not possible!
Special features when making data entries at address connections AT
and AR when using SINEC H1 layer 7 (STF):
Input sequence:
"Channel name.address stage 1. address stage 2"
