Entering settings
Procedure
1. Set the operation of the rear SPA/IEC port to "IEC".
The operation of the rear SPA/IEC port can be found on the local
HMI at:
Configuration/TerminalCom/SPA-IECPort
Now the SPA/IEC port operates as an IEC port.
2. Set the slave number and baud rate for the rear IEC port
The slave number and baud rate can be found on the local HMI at:
Configuration/TerminalCom/IECCom/Communication
Set the same slave number and baud rate as set in the IEC master
system for the terminal.
3. Set the main function type of the terminal.
The main function type can be found on the local HMI at:
Configuration/TerminalCom/IECCom/FunctionType
The main function type can be set to values from 1 to 255 accord-
ing to the standard. The value zero is default and corresponds to
not used. Examples of values that can be used are:
Table 8: Main function type examples
Value

If the setting "OpFnType" is set to "ON" then the set value for
function type will be used for all event blocks and the disturbance
recorder, otherwise the setting on each event block and the distur-
bance recorder will decide the function type of that function block.
Function type according to IEC 60870-5-103
