may require to
enter a password for this operation.
3.
In the
Password for Safety Program
dialogue box,
enter the appropriate password.
4.
To edit the Danfoss device properties, double-
click the device.
5.
In the
Device name
field, enter the same name as
shown in
12-08 Host Name
.

6.
Select the module and add the following I/O
protocol:
PROFIsafe 30 -6/6 Bytes, Standard
Telegram 30
.

7.
To edit the PROFIsafe settings. ouble-click

8.
Select the

tab in the
Properties
dialogue
box, .

9.
Edit the required settings.
The following 3 parameters can be changed, but normally
it is only necessary to change the
F_Dest_Add
parameter:
•
F_Source_Add - the PROFIsafe address of the
PROFIsafe master.
•
F_Dest_Add - the destination address of Safety
Option MCB 152. This address must be the same
as set in MCT-10 Set-up Software,
42-61 Destination Address
.
•
F_WD_Time - the watchdog time for the
PROFIsafe connection.
Watchdog time
The watchdog time setting depends on the speed of the
PROFINET connection and the number of devices.
Valid range: 67-65535 ms.
Default value: 150 ms.
If the safety option does not receive a new valid PROFIsafe
telegram within this time, the safety option enters the safe
state. The watchdog time is configured to a value that is
long enough to avoid false alarms and short enough to
detect errors in communication. The formula for
calculating the minimum watchdog time:
F_WD_Time=2 * BT + HAT + DAT
•
BT = Bus cycle time.
•
HAT=Host acknowledgement time.
•
DAT=Device acknowledgement time.
Use the watchdog time to calculate the safety function
response time (SFRT) for the system. For more information,
see the PROFIsafe profile description at
