→ IRC combination
Inter Relay Communication, IRC, is used for directly exchanging process information
between SIPROTEC 4 devices. You require an object of type IRC combination to con-
figure an inter relay communication. Each user of the combination and all the neces-
sary communication parameters are defined in this object. The type and scope of the
information exchanged between the users is also stored in this object.

The ISO 9000 ff range of standards defines measures used to assure the quality of a
product from the development stage to the manufacturing stage.
The link address gives the address of a V3/V2 device.
The right pane of the project window displays the names and icons of objects which
represent the contents of a container selected in the tree view. Because they are dis-
played in the form of a list, this area is called the list view.

Masters may send data to other users and request data from other users. DIGSI op-
erates as a master.
Metered values are a processing function with which the total number of discrete
similar events (counting pulses) is determined for a period, usually as an integrated
value. In power supply companies the electrical work is usually recorded as a metered
value (energy purchase/supply, energy transportation).
MLFB is the abbreviation for "MaschinenLesbare FabrikateBezeichnung" (machine-
readable product designation). This is the equivalent of an order number. The type and
version of a SIPROTEC 4 device are coded in the order number.
This object type contains information on both partners of a modem connection, the
local modem and the remote modem.
A modem profile consists of the name of the profile, a modem driver and may also
comprise several initialization commands and a user address. You can create several
modem profiles for one physical modem. To do so you need to link various initialization
commands or user addresses to a modem driver and its properties and save them
under different names.
