Counter - Diagnostic and interrupt
The parameterization allows you to define the following trigger for a
hardware interrupt that may initialize a diagnostic interrupt:
• Status changes at an input (at opened SW gate)
• Status changes at the HW-gate (at opened SW gate)
• Reaching a comparison value
• Overflow respectively at overrun upper counter limit
• Underflow respectively at underrun lower counter limit
A hardware interrupt causes a call of the OB 40. Within the OB 40 you may
find the logical basic address of the module that initialized the hardware
interrupt by using the Local word 6. More detailed information about the
initializing event is to find in the local double word 8.
The local double word 8 of the OB 40 has the following structure:
Local byte Bit 7 ... Bit 0
8 Bit 0: Edge at I+0.0
Bit 1: Edge at I+0.1
Bit 2: Edge at I+0.2
Bit 3: Edge at I+0.3
Bit 4: Edge at I+0.4
Bit 5: Edge at I+0.5
Bit 6: Edge at I+0.6
Bit 7: Edge at I+0.7
9 Bit 0: Edge at I+1.0
Bit 1: Edge at I+1.1
Bit 2: Edge at I+1.2
Bit 3: Edge at I+1.3
Bit 4: Edge at I+1.4
Bit 5: Edge at I+1.5
Bit 6: Edge at I+1.6
Bit 7: Edge at I+1.7
10 Bit 0: Gate counter 0 open (activated)
Bit 1: Gate counter 0 closed
Bit 2: Over-/underflow/end value counter 0
Bit 3: Counter 0 reached comparison value
Bit 4: Gate counter 1 open (activated)
Bit 5: Gate counter 1 closed
Bit 6: Over-/underflow/ end value counter 1
Bit 7: Counter 1 reached comparison value
11 Bit 0: Gate counter 2 open (activated)
Bit 1: Gate counter 2 closed
Bit 2: Over-/underflow/end value counter 2
Bit 3: Counter 2 reached comparison value
Bit 7 ... 4: reserved
