| For information on "Diagnostics" and "System alarms", refer to the Diagnostics The compact CPU can generate a hardware interrupt for the following events: | |
| Below low limit 1 ● Above high limit 1 |
|
| You can find detailed information on the event in the hardware interrupt organization block with the "RALARM" (read additional interrupt information) instruction and in the STEP 7 (TIA |
Portal) online helpThe start information of the organization block includes information on which channel of the
analog on-board I/O triggered the hardware interrupt. The figure below shows the
assignment to the bits of double word 8 in local data.If the two high limits 1 and 2 are reached at the same time, the analog on-board I/O always
signals the hardware interrupt for high limit 1 first. The configured value for high limit 2 is
irrelevant. After processing the hardware interrupt for high limit 1, the compact CPU triggers
the hardware interrupt for high limit 2.
The analog on-board I/O behaves accordingly when the low limits are reached
simultaneously. If the two low limits 1 and 2 are reached at the same time, the analog onboard
I/O always signals the hardware interrupt for low limit 1 first. After processing the
hardware interrupt for low limit 1, the analog on-board I/O triggers the hardware interrupt for
low limit 2.A diagnostics alarm is output for each diagnostics event and the ERROR LED flashes on the
analog on-board I/O. The diagnostics alarms can, for example, be read out in the diagnostics
buffer of the CPU. You can evaluate the error codes with the user program.Resistance of encoder circuit too
high
Use a different encoder type or modify the
wiring, for example, using cables with
larger cross-section
Interruption of the cable between the
analog on-board I/O and sensor
Connect the cable
Channel not connected (open) • Disable diagnostics
• Connect the channel
Overflow 7H Measuring range exceeded Check the measuring range
The output value set by the user
program exceeds the valid rated
range/overrange
Correct the output value
Underflow 8H Value below measuring range Check the measuring range
The output value set by the user
program is below the valid rated
range/underrange
Correct the output value
Short-circuit to ground 1H Overload at output Eliminate overload
Short-circuit of output QV to MANA Eliminate the short-circuitA diagnostics alarm is output for each diagnostics event and the ERROR LED flashes on the
digital on-board I/O. You can read out the diagnostics alarms, for example, in the diagnostics
buffer of the CPU. You can evaluate the error codes with the user programhe digital on-board I/O cannot trigger an
interrupt because the previous interrupt
was not acknowledged; possibly a configuration
error
• Change the interrupt processing in the
CPU and reconfigure the digital onboard
I/O.
• The error persists until new parameters
are set for the digital on-board I/OTime sequence of the A and B signals
of the incremental encoder do not
meet certain requirements
• Possible causes:
– Signal frequency too high
– Encoder is defective
