Plug-in module position E: ETH-BA-2EL: 2x electric Ethernet 100 Mbit/s, RJ45
Communication Protocols: applicable for DIGSI 5, IEC 61850-8-1
MMS and
GOOSE, IEC 60870-5-104, DNP3 TCP, Modbus TCP,
Synchrophasor (IEEE
C37.118 - IP), Profinet IO, SUP, DHCP, SNTP, SNMP, etc.
Redundancy protocols: Line Mode, RSTP, HSR, PRP
Plug-in module position F: Port is available but not assembled
Functions:
Function points class: Base + 200 function points
Note on function-points class
The function-points class results from the sum of the function points of the selected functions. You can
apply these functions according to the selected function-points class. The device also allows each other
selection of functions if the sum of the required function points is within the selected function-points
class.
From Version V9.3 on the function-points class "1400+" is withdrawn. With this class function-points
exceeding the limit of 1400 were free of charge. The maximum function-points class is now 1400. If a
function-points budget of more than 1400 points is required for a device the application
Function-Point-Manager need to be applied. All function points are liable to cost.
In the engineering phase DIGSI 5 checks that the selected configuration is suitable (capable of running
in the device) before loading it to the device.
Miscellaneous:
Warranty: 2 years
Special Approvals: Without
Firmware: Current version
