3.1.2.9 Transmitted Telegrams vs. Network Type and I/O Module Assembly
Depending on the selected Network type (ref. to Figure 3-1), the parameters to the
transmisson of the harmonics (see chapter 2.1.2) and the assembled I/O modules
either all or only a selected number of the above descriped telegrams are sent to the
IEC 60870-5-103 master on request of class 2 data.
For an association of the measured quantities to the selected Network type please
refer to Table 3-1 in the SIMEAS P50 Device Manual (refer to page 3 for the order
number of this document).
Table 3-3 Transmitted telegrams vs. Network type and I/O module assembly
The telegrams are transferred sequentially, i.e. every time the IEC 60870-5-103 mas-
ter requests class 2 data, the IEC 60870-5-103 slave sends the next following tele-
gram in the order shown in Table 3-3.
When the last additional measurands telegram was sent, it starts with "Compatible
Measurands II" again.
The IEC 60870-5-103 master can request
• only one telegram or
• a part of the telegrams or
• all telegrams
supported according to the Network type from one device and then change to the
next device.
