General Precautions
● If parameter telegram ending selection is set to value Character Timeout, the value in the
parameter Character Timeout must be set to 0. The parameter End Value must be set to 32
(equivalent to 32-bits character timeout). Only 32-bits character timeout is supported.
● Checksum is only supported if a telegram ending selection is active.
● Please refer to AC500 serial channel documentation for additional precautions.
Precautions for RS-485/RS-422
DTE/DCE is not supported. The parameter RTS Control must be set to value Telegram or to
None.

Configuration with Automation Builder
The physical layers are selectable as submodules in PROFINET configuration
(parameter Physical Layer not visible and fixed with the correct value). Certain
parameters are not visible if a certain physical layer is selected. This concept of
parameterization provides a better usability than configuring via GSDML (see
below).
Configuration via GSDML (use by non-ABB PROFINET configuration tool)
All parameters are visible independent of the configured physical layer (via
parameter "Physical Layer" ). The user must take precautions for each param-
eter since certain parameter values are invalid for certain physical layers. Nev-
ertheless, the CI5xx-PNIO module performs a parameter check depending on
the configured physical layer and generates a diagnosis message (parameter
error) in the case of error.
