6. Function blocks
6.2 Interrupt function blocks
For function blocks IE01 – IE08 and IC01 – IC08, device inputs I01 – I08 can be assigned
freely.
For function blocks IT01 – IT08, an interrupt that is not yet in use is assigned in easySoft
7. The interrupt sources used by the CF, CH, and CI high-speed counters are also con-
sidered to be in use within this context.
Each device input and each interrupt source can only be used once.
Exceptions:
l
For CI01, the instance of I02 can be used by an IT interrupt function block.
l
For CI02, the instance of I04 can be used by an IT interrupt function block.
l
For each interrupt function block IC, the instance of the second input of an IT func-
tion block can be used if the Counter with 2 counter inputs mode has not been selec-
ted.
These exceptions are taken into account by the plausibility check and by the program
compilation routine in easySoft 7. The maximum number of 8 interrupts is also taken
into account within this context.

IE01…IE08 One input, I01 – I08 can be assigned freely (max. 8, none can be assigned more than
once)
IC01 – IC08 Two inputs, I01 – I08 can be assigned freely (max. 8, none can be assigned more than
once)
IT01…IT08 Automatically assigns the user interrupts 1 to 8 that are still available (only for instances
of I01 – I08 that are not in use by other function blocks)
