6. Enable the desired diagnostic interrupts.
Monitoring is always active. When an error is detected, a diagnostic interrupt is only
triggered when the corresponding diagnostic interrupt is enabled in the device configuration.
7. Enable the desired hardware interrupts.
With the help of the following event types, parameterize the triggering of a hardware
interrupt if they are to be used for controlling dosing. If the dosing signals are to be switched
in the cyclic program via the FB, the hardware interrupts can be ignored.
– Coarse flow (incoming)
– Coarse flow (outgoing)
– Fine flow (incoming)
– Fine flow (outgoing)
– Emptying (incoming)
– Emptying (outgoing)
– Hardware interrupt 4 (event freely definable in DR07)
– Hardware interrupt 5 (event freely definable in DR07)
– Hardware interrupt 6 (event freely definable in DR07)
– Hardware interrupt 7 (event freely definable in DR07)
– Hardware interrupt 8 (event freely definable in DR07)
You can select any combination of events for hardware interrupt triggering.
You can obtain detailed information on the event in the hardware interrupt organization
block with the instruction "RALRM" (read additional interrupt info) and in the information
system of STEP 7 (TIA Portal).
The event that triggered the hardware interrupt is logged in the start information of the
organization block. The following figure shows the assignment to the bits of double word 8
in local data.
