Second interface SI2
You can optionally use the second interface of the CPU 928B as:
••
A PG interface (for PG and operator panels)
••
Interface for the RK 512 computer link
••
Interface for data transmission with procedures 3964/3964R
••
Interface for data transmission with the "open driver"
••
Interface for data transmission via the SINEC L1 bus (from
Version 6ES5 928-3UB12).
To utilize the second interface as the PG interface, you need the
••
PG submodule.
You need one of the following interface submodules for the RK 512
computer link, for data transmission with procedures 3964/3964R and
for data transmission with the "open driver":
••
V.24 submodule (RS 232C)
••
TTY submodule
••
RS422 A/485 submodule (only in the RS422 A module).
To utilize the second interface for data transmission via the SINEC L1
bus, you need the
••
SINEC L1 submodule (from Version 6ES5 928-3UB12).
The CPU 928B is delivered without an interface submodule. You can
operate the CPU 928B without an integral interface submodule. The
opening to accept a submodule in the front plate is closed by a cover.
Only remove the cover to fit an interface submodule.
A description of interface submodules can be found in Section 5.8,
and the order numbers in the ordering information.
A detailed description of the second interface can be found in the
CPU 928B Communication Manual.
