(IIHFW The status of the PPS communication will automatically be displayed on this line. If
communication is error-free, the controller identifies the unit connected by displaying
the identification number, in addition to the device address.
'LVSOD\V The display features a PPS address and an identification code.
$GUHVVH336 The display is comprised of PPS address and a device identification code:
- Note:
• These peripheral devices can only operate under the respective PPS address. If
one of these devices is not used, the PPS address can be allocated to some other
peripheral device (allocation is one-way). Assignment of all the other peripheral de-
vices to the PPS addresses can be made randomly.
• Since every regulator has a specific and confined PPS address space, the same
PPS addresses can be assigned to each device.

The regulator only allows the connection of digital peripheral devices. Analogue devices
are not compatible. The digital devices transmit their specific identification code to the
regulator. This enables the identification of the type of unit using the following list:
- Note:
• The display of a PPS address with the identification code means that the commu-
nication with the corresponding unit is correct.
• If neither PPS address or identification code are displayed, communication is faulty
or wrong.
• Non compatible units are displayed but generate error message 145 (line 50).
