General
Note
In the following, "RTD box" is used to designate both the temperature detection via RTD box (RS485 and Eth-
ernet port) and the temperature measurement via the I/O 2 extension module.
Temperature detection is only effective and accessible if it was activated during configuration of the protection
functions (Section 2.1.1) and if the connection type was selected. Temperature supervision is activated at
address 190 RTD INPUT. The number of sensor inputs and the communication mode are set at address 191
RTD CONNECTION. The temperature unit (°C or °F) is set in the Power System Data 1 at address 276 TEMP.
UNIT.
When connecting the RTD box 7XV5662-8AD10 with 12 temperature sensor inputs via the Ethernet interface,
set the same IP address for the parameters 9001 IP address[0] through 9004 IP address[3] and 9006
through 9009. At address 9000 UDP Port you define the communication port, e.g. 5000. At address 9005 UDP
Port enter an address that must be 1 higher than the address at 9000, e.g. 5001.
