STEP 7 (TIA Portal) assigns the addresses automatically. You can change the addresses in
the hardware configuration of STEP 7 (TIA Portal), i.e. freely assign the start address. The
addresses of the channels are based on the start address.
The letters "a" to "d" are lasered on the on-board I/O. "IB a", for example, stands for start
address input byte a. "QB x", for example, stands for start address output byte x.As of firmware version 2.0, the analog and digital on-board I/O support the value status as
diagnostics option. You activate the use of the value status in the hardware configuration of
STEP 7 (TIA Portal). Value status is deactivated by default. You can activate/deactivate the
value status of the digital on-board I/O for X11 and X12 independently of each other.
When you activate the value status, the input area of the digital on-board I/O (X11/X12)
contains four additional bytes, which provide the QI bits to the 16 digital input channels and
16 digital output channels. You access the QI bits through the user program.
Value status of input channels
Value status = 1 ("Good") indicates that the value of the assigned input at the terminal is
valid.
Value status = 0 ("Bad") indicates that no or too little supply voltage L+ is applied at the
terminal and that the read value is therefore not valid.
Value status of output channels
The value status = 1 ("Good") indicates that the process value specified by the user program
is correctly output at the terminal.
The value status = 0 ("Bad") indicates that the process value output at the hardware output is
incorrect or the channel is used for technology functions.
Possible cause for value status = 0:
● The supply voltage L+ is missing at the terminals or is not sufficient
● Outputs are inactive (for example, CPU in STOP)
● Technology functions (HSC, PWM or PTO) use the channel
Note
Behavior of the value status at the output channels for technology functions
The output channels return the value status 0 ("Bad") when a technology channel (HSC,
PWM or PTO) is used. It does not matter in this context whether the output value is incorrect
or notYou can find a description of the control interface in the section Assignment of the control
interface of the high-speed counters (Page 48). You can find a description of the feedback
interface in the section Assignment of the feedback interface of the high-speed counters
(Page 51)The analog on-board I/O is set to voltage measurement type and measuring range ±10 V by
default for the inputs on channels 0 to 3. By default, channel 4 is set to resistance measuring
type and measuring range 600 Ω. If you want to use another measurement type or
measuring range, change the parameter settings of the analog on-board I/O with STEP 7
(TIA Portal).
Disable unused inputs to prevent disturbances that cause incorrect behavior (e.g. triggering
of a hardware interrupThe analog on-board I/O is set to voltage output type and output range ±10 V as default for
the outputs. If you want to use another output range or output type, you need to change the
parameter settings of the analog on-board I/O with STEP 7 (TIA Portal).
Output types and output ranges
The following table shows the output type and the corresponding output rangesYou specify the properties of the analog on-board I/O during parameter assignment with
STEP 7 (TIA Portal). The tables below list the parameters that can be set for inputs and
outputs, respectively.
When parameters are assigned in the user program, they are transferred to the analog onboard
I/O via data records with the WRREC instruction, see section Parameter assignment
and structure of the parameter data records of the analog on-board I/O (Page 162).
All parameters can

changed by reassigning parameters in RUN with single channel parameter assignment (data records 0 to 4) if all other
input channels are disabled. The diagnostics for short circuit to ground can be configured for the voltage output type.
Short-circuit detection is not possible for low output values. The output voltages must
therefore be under -0.1 V or over +0.1 V.
Wire break detection
The diagnostics for wire break can be configured for the current output type. Wire break
detection is not possible for low output values; the output currents must therefore be below -
0.2 mA or above +0.2 mAYou specify the properties of the digital on-board I/O during parameter assignment with
STEP 7 (TIA Portal). The tables below list the parameters that can be set for inputs and
outputs, respectively.
When parameters are assigned in the user program, they are transferred to the digital onboard
I/O via data records with the WRREC instruction, see section Parameter assignment
and structure of the parameter data records of the digital on-board I/O (Page 170).
The use of a digital input by a technology channel
When a digital input is in use by a technology channel (HSC, PTO or PWM) the
corresponding digital input channel remains fully usable without any restriction.
Use of a digital output by a technology channel
When a digital output is in use by a technology channel (HSC, PTO or PWM), the following
restrictions apply to the use of the corresponding digital output channel:
● Output values for the digital output channel are not effective. The output values are
specified by the technology channel.
● The CPU STOP behavior configured for the digital output channel is not effective. The
reaction of the output to CPU Stop is specified by the technology channel.
● With activated value status (Quality Information) for the DI16/DQ16 submodule, the QI bit
for the digital output channel shows the value 0 (= Status "Bad").
● The current state of the digital output is not returned to the process image output. In the
PTO operating mode, you can only observe the switching operations of the assigned
digital outputs directly at the output. In the PWM operating mode and with high-speed
counters (HSC), you can observe the current state additionally via the feedback interface.
Note, however, that high frequencies may no longer be observed under certain
circumstances due to an excessively low sampling rate.When the digital output is controlled by a
technology channel (HSC, PTO or PWM),
this parameter is not effective. In this case,
the technology channel specifies the reaction
of the digital output to CPU STOP.

1) All parameters can be set for on a channel-specific basisThe CPU has three LEDs for displaying the current operating mode and diagnostics status.
The following table shows the meaning of the various combinations of colors for the
RUN/STOP, ERROR and MAINT LEDs.There is no Ethernet connection between the PROFINET interface of the PROFINET device
and the communication partner.
No data is currently being sent/received via the PROFINET interface.
There is no LINK connection.
LED flashes green
The "LED flashing test" is being performed.
LED lit green
There is an Ethernet connection between the PROFINET interface of your PROFINET device
and a communication partner.
LED flickers yellow
Data is currently being received from or sent to a communications partner on Ethernet via
the PROFINET interface of the PROFINET devicee CPU is in STOP mode.
? As long as the STOP ACTIVE LED is lit up, switching the CPU to RUN mode is only
possible using the RUN button.
? The CPU can then no longer be set to RUN mode via the display operation or via online
functions. The state of the buttons is retained at power-off. If the CPU does not start up
automatically after a power-on, you have to keep the STOP button pressed during startup
until the STOP ACTIVE LED is activated.
? If an automatic start-up is to be reliably prevented after a power-up, the STOP button has
to be kept pressed during the start-up of the CPU until the STOP ACTIVE LED is activated.
LED off
? The CPU is set to "STOP" mode using the display or programming device and not with
the STOP button on the device.
? The CPU is in RUN mode.The following tables explain the meaning of the status and error displays. Corrective
measures for diagnostic alarms can be found in the section Interrupts and diagnostics of the
analog on-board I/O (Page 131).No voltage or voltage too low. ? Turn on the CPU and/or the system power
