Troubleshooting

Condition
Cause
Slow or no update of
Protocol data is available for active IED applications
data, reports disabled
and the IED system. Active IED applications mean the
function blocks that have been added into the IED
configuration using the Application Configuration tool in
PCM600. IED system data is always available and is
not dependent on the application configuration.
An IED variant has a standard application configuration
that has been done in advance. This configuration can
be modified with PCM600. It is also possible to start a
completely new configuration from an emptied
configuration state in Application Configuration. When
a new IED configuration is created from an empty
configuration state, an additional PCM600 check must
be done at the end.

Communication Protocol Manual
>10R11I31: Read register 11 as an unsigned integer ... map to Profibus offset
4...5
>10R12I31: Read register 12 as an unsigned integer ... map to Profibus offset
6...7
>10R13I31: Read register 13 as an unsigned integer ... map to Profibus offset
8...9
The bits in register 14 can be fetched as an integer value.
>10R14I31: Read register 14 as an unsigned integer ... map to Profibus offset
10...11
Profibus offsets 4...11 values assembled sequentially are achieved more efficiently by
reading two Modbus registers at a time using only two SPA-polls.
>10R11I42:CC Read registers 11-12 as a 32 bit hex value, into Profibus offsets
4...7
>10R13I42:CC Read registers 13-14 as a 32 bit hex value, into Profibus offsets
8...11
The value format was changed into hex values. This creates a shorter SPA response
data value which saves SPA-communication bandwidth. I41 (unsigned 32 bit integer)
also can be used. SPA ZC-302 accepts both of these value types.
It does not matter how the separate data values have been polled into its Profibus
memory area from the SPA ZC-302 point of view. It is not necessary to poll each
object in one by one. This means that the User Definable Modbus area is sequentially
filled up with the Modbus values to be transferred to Profibus offset octets. Then the
data can be polled into SPA ZC-302 using two register reads at a time.
Troubleshooting
Vendor-specific implementation
Remedy
Select manually the check boxes for clients of all visible
61850 data sets in the IEC 61850 Configuration tool,
see the engineering guide for detailed instructions. This
procedure enables reporting for the data sets, and
report control blocks should appear on the Report
Control tab.
