The Bay Processing Unit 6MD665 allows direct communication with SICAM HV mod-
ules. The process bus interface is equipped with an Ethernet module.
2.9.1 Description
General
Upon delivery of the device, there are no process information or allocations present.
The information is entered by importing data from
• the parameterisation tool for SICAM HV modules ModPara and
• from the information catalogue of the parameterisation tool DIGSI
®
Between the two parameterisation tools, carry out an export of the parameterised
information from ModPara to DIGSI
®
so that the process information of the submod-
ules SICAM HV can be converted into process objects of the SIPROTEC
®
4 device
6MD665.
For a file transfer, the Process Communication Unit (PCU) submodule structure is to
be illustrated in a two-level directory tree in the parameter set of the SIPROTEC

device 6MD665. In addition, data must be made available to the PCUs via the
process bus (communication addresses).
The parameterisation sequence is set as follows:
• ModPara (parameterise SICAM HV module)
• DIGSI
®
(parameterise SIPROTEC

4 device 6MD665)
• ModPara (parameterise communication module)
