● "Addresses" tab
The address area for the process image is configued in this tab. The process image is a
memory area in the controller which the HMI device and controller access together. At the
beginning of the cyclic control program the signal states of the inputs of the HMI device
are transferred to the controller via the process input images, PII. At the end of the cyclic
program the process image of the outputs, PIQ is transferred as a signal state to the HMI
device.
Parameter
Meaning
Input > Address > Start of
Address Area
Start address of the inputs in the process image. The safety-relevant
user data of the HMI device is shown.
The default depends on the controller used.
Input > process image
Process image to which the address range of the inputs belongs, PII.
This parameter cannot be set with controllers of the
SIMATIC CPU 300 type.
Output > Address > Start of
Address Area
Start address of the outputs in the process image The safety-relevant
user data of the HMI device is shown.
The default depends on the controller used.
Output > process image
Process image to which the address range of the outputs belongs,
PIQ.
This parameter cannot be set with controllers of the
SIMATIC CPU 300 type.
● Tab "PROFIsafe"
Here you must set the parameters "F_Dest_Add" and "F_WD_Time".
Parameter
Meaning
F_SIL
Safety class of the Mobile Panel 277F IWLAN
The value of the parameter is set to "SIL 3".
This parameter cannot be modified.
F_CRC_Length
Length of the CRC for the consistency check.
The value of the parameter is set to "3 byte CRC".
This parameter cannot be modified.
F_Block_ID
This parameter must be set to the value "0", as there is no checksum
of the individual device parameters.
F_Par_Version
Implemented PROFIsafe version.
The value of the parameter is set to "1". This means that PROFIsafe
V2 is used.
This parameter cannot be modified.
F_Source_Add
PROFIsafe address used to uniquely identify the source throughout
the network and station.
The address is assigned automatically. The "F_Source_Add"
parameter can have a value between 1 and 65534.
This parameter cannot be modified.
