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.
