Section 16
Station communication
The high and low limit settings provides limits for the high-high-, high, normal, low and low-low
ranges of the measured value. The actual range of the measured value is shown on the range
output of MVGAPC function block. When a Measured value expander block (RANGE_XP) is
connected to the range output, the logical outputs of the RANGE_XP are changed accordingly.

16.2.6.2 Application
Dual ethernet port link status (PRPSTATUS) together with IEC 62439-3 parallel redundancy
protocol (PRP) are used to supervise and assure redundant Ethernet communication over two
channels. This will secure data transfer even though one communication channel might not be
available for some reason. Together PRPSTATUS and PRP provide redundant communication over
station bus running IEC 61850-8-1 protocol. The redundant communication use both port AB and
CD on OEM module.
