To use the 32Mbit Flex mode, set the rotary switches as follows: S1 = 1 and S2 = 1 … F

32Mbit Flex mode is the delivery state of the device (with S2 = 1)

With this setting, the device operates with 32Mbit Flex telegram on the FO side. A bidirectional FO connection is needed to the ibaPDA system. The configuration data is transferred from ibaPDA to the device via FO connection. Sniffer function and active slaves can be used simultaneously.

Depending on the timebase, up to 4060 bytes per cycle can be acquired and recorded with up to 1024 analog values and 1024 digital values. When transferring the maximum data volume of 4060 Bytes the timebase must not be faster than 1.4 ms. With a timebase of 1 ms, up to 3100 bytes can be transferred. The shortest cycle time is 0.5 ms (1540 bytes). The data types BYTE, WORD, DWORD, INT, DINT, FLOAT and S5 FLOAT in big/little endian format are supported.

When the device is operated in a ring topology with other 32Mbit Flex devices, the data volume that can be transmitted, decreases accordingly.

Up to 8 active slaves can be optionally assigned to Bus0/1.

With 32Mbit Flex, output signals of ibaPDA can be sent to the PROFIBUS master. Thus, e. g. certain signal values can be monitored, a warning message is being issued in case a limit value is exceeded or other events are signalized.

Note
	ibaPDA processes output signals with lower priority compared to the acquisition of input signals with a cycle not faster than 50 ms depending on the I/O configuration.

The redundancy mode can be used in 32Mbit Flex mode, see chapter Redundancy mode. The use of redundancy mode requires an additional license.
