3 settings are available for mirror mode:
Disabled
: The data is not mirrored so that this ibaPDA system is the only system
capable of configuring the devices and acquiring data.
Master
: This ibaPDA system configures the Flex devices on the link. The data and
the device configurations are mirrored so that other ibaPDA systems can also ac-
quire the data.
Slave
: This ibaPDA system receives the device configuration from the master
ibaPDA so that it can acquire the data configured by the ibaPDA master.
The slave ibaPDA can get the device configuration from the master ibaPDA using the
"autodetect" function. A slave ibaPDA cannot change the device configuration. The mod-
ules in the signal tree are displayed with a padlock symbol in the slave ibaPDA.
Figure 48: Modules in the signal tree
When acquisition has been started on the slave ibaPDA, the slave waits until it receives
the configuration from the master. If this configuration is different from the current con-
figuration, the slave will load the new configuration.
If the slave does not receive a configuration from the master within 6 s, ibaPDA will gen-
erate an error message. If the option "Allow start of the acquisition when the link is in
slave mirror mode and master isn’t connected" is enabled, acquisition will be started
anyway with the last configuration.
Figure 49: Link – Configuration tab
When the master ibaPDA changes the configuration while the slave ibaPDA is acquiring
data, the slave will automatically restart acquisition.
10.6.5.2 Calculating the telegram size with 32Mbit Flex
The data size per participant is dynamically allocated in a 32Mbit Flex ring and is calcu-
lated by ibaPDA. The data size depends on the configured number of analog and digital
signals and the smallest configured timebase in the ring.
ibaPDA version 6.33.1 and higher provides a simulator (32 Mbit/s Flex frame simulation)
which calculates the data size that can be transmitted by each participant via the FO link
using the 32Mbit Flex protocol. Open the "Configuration" tab for this purpose.
