“Options” tab
In the “Connection” box, you can set the automatic monitoring of the connection
to the PROFINET IO controller.
− The default is “Automatic setting”: Transmission rate and direction (full
duplex/half duplex) of the data transmission are set to the optimum value by
the connected partners.
− If you select “Automatic setting (monitor)”, the connection status is
monitored. If there is a disruption on the connection, a diagnostic interrupt
(error type 8008
H
) is generated at the diagnostic address of the port.
When automatic setting is selected, the “runtime check” cannot be used.
Configuring the Properties of the AS-i Line
If you double-click on row 1 for AS-i line 1 (AS-i addr.: “ [1] ”) or on row 67 for AS-i
line 2 (AS-i addr.: “ [2] ”) in the configuration table, you open the properties dialog of
the relevant AS-i line and can set the following parameters:
S “General” Tab
− Display of the essential master data of the module
− Entering a comment
S “Addresses” tab
Setting the diagnostic address of the AS-i line
S “Packing”
Here, you can pack the address areas reserved on the link for the AS-i slaves.
Reducing the size of the address areas optimizes the memory available on the
controller.
In the default assignment with placeholder modules, an area of 1 byte is
reserved for each I/O module. Since a maximum of 4 bits can be assigned to a
digital AS-i slave in one transfer direction, data exchange is possible with any
slave. Packing concentrates the required address areas of the I/O modules
without any gaps and releases the memory that is not required. The packed
data is transferred in a data field assigned to the line proxy.
The fields in the “Pack” tab of the properties dialog have the following meaning:
− The required length of the data field of the line proxy is displayed in bytes in
the “Inputs” and “Outputs” boxes under “Assigned Length”.
− The “Start” input box shows the start address of the data field. You can
assign a different value here.
− In the “Reserved Length” input box, you can reserve address space for
future expansion by increasing the proposed value.
Notice
Packing the address spaces cannot be reversed.
