allowing connection with up to five IEC 60870-5-104 client devices. For each client, the driver has a
unique event queue with the following characteristics
Size: 4.500 events
Overflow policy: keeps the most recent event
Follow the steps below in order to set this protocol:
Add the IEC 60870-5-104 Server protocol instance to one of the available Ethernet channels
(NET 1 to NET 6)
To execute this procedure see, Inserting a Protocol Instance
Set the Ethernet interface. See Ethernet Interfaces Configuration
Set the general parameters of the IEC 60870-5-104 Server protocol with the connection modes
Port or IP (for the later, set TCP port number also)
Add and set the devices, defining the requested parameters
Add and set the IEC 60870-5-104 mappings, specifying the variable name, object type, object
address, size, range, event class, dead band and dead band type
Set the link layer parameters, specifying the addressing, the timeouts communication and the
communication parameters
Set the link layer parameters, configuration of the synchronism , commands, as well as the
transmission mode of
