See the product-specific point list manuals for detailed information
concerning the contents of frames 6 and 7.
Contents of frames 6 and 7 are equal if no additional, less frequently updated
values exist in the IED.

As a third option, the user can freely compose an own private Class 2 frame using
PCM600. The user can also configure the Function Type and Information Number
for this user-definable Class 2 frame through the setting parameters UsrFType n
and UsrInfNo n via LHMI path Configuration/Communication/IEC
60870-5-103. Default values are FUN = 10, INF = 230.

Selecting Class 2 frame into use

The Class 2 frame is selected via LHMI path Configuration/Communication/IEC
60870-5-103/Frame1InUse n. The user can select between the user-defined frame
0, standard frames 1 to 5, or IED-dependent frames 6 and 7. Selection of frames 0
to 7 is possible even if the IED does not produce all the values required by the
mentioned Class 2 frames. Values that are not available in the IED is set to 0 in the
selected Class 2 data frame.
Using several Class 2 frames simultaneously
Using several Class 2 frames simultaneously is not a standard feature. However, it
is possible to define that the IED sends more than one Class 2 frame to the master.
Actually up to four Class 2 frames can be defined. The additional Class 2 frame
selections is defined in setting parameters Frame2InUse n, Frame3InUse and
Frame4InUse. For example, if Frame1InUse is set to "6" and Frame2InUse is set
to "0", the IED gives out Class 2 frame 6 and Class 2 frame 0 (user-definable
frame) responses to every second Class 2 poll made by the master.

Scaling Class 2 measurands

All Class 2 measurands can be rescaled separately using PCM600. The scale value
defines the highest value expressed by the IEC 60870-5-103 measurand. Values 1.2
and 2.4 are standard values but the IED can actually accept any value. For
example, scale 4.0 for IL1 enlarges the measurand range to -4.0*In...+4.0*In. The
IEC 60870-5-103 measurand value is always signed, regardless if the original value
is a positive only value.
