6.1.6. IEC 103
IEC 103 is short for international standard IEC 60870-5-103. Arcteq implements a secondary station
(slave). The IEC 103 protocol can be selected for the available serial ports of the device. A master or
primary station can communicate with the Arcteq device and receive information by polling from the
slave device. Disturbance recordings transfer is not supported.

IEC 103 parameters can be found in the following table.
Parameter
Range
Description
Slave address
[1…254]
IEC 103 slave address for the unit.
Measurement interval
[0…60000]ms
Interval setting for the measurements update.
6.1.7. DNP3
DNP3 is a protocol standard which is controlled by the DNP Users Group at
. The
implementation of a DNP3 slave is compliant with DNP3 Subset De nition Level 2, but contains also
functionality of higher levels. For detailed information see the DNP3 Device Pro le document.
DNP3 parameters can be found in following table.
Parameter
Range
Description
Slave address
[1…65519]
DNP3 slave address for the unit.
Master address
[1…65519]
DNP3 address setting for allowed master.
Link layer timeout
[0…60000]ms
Timeout of link layer
Link layer retries
[1…20]
Number of link layer retries
Application layer timeout
[0…60000]ms
Application layer timeout
Application layer con rmation
[0=No,1=Yes]
Application layer con rmation enable.
Time sync request interval
[0…60000]ms
Request interval for synchronization.
6.1.8. IEC 101/104
Standards IEC 60870-5-101 & IEC 60870-5-104 are closely related. Both are derived from IEC 60870-
5 standard. On the physical layer IEC 101 uses serial communication but IEC 104 uses Ethernet
communication.
The IEC 101/104 implementation works as a slave in unbalanced mode.
For more detailed information see the IEC101 Pro le Checklist document.
IEC101/104 parameters can be found in following table.
