c475_ft_frequency

	status.i4.v = c475_ft_frequency(root_name.ch.d, ft_freq.i4.r)

	This routine returns the time table (f(t)) update frequency for a
	C475 family device.

	root_name	root name of device
			(dio_get_terse_name_length characters per device)
	ft_freq		returned f(t) frequency in Hz
			(1000, 5000, 10000, 50000, or 100000)

	This function returns status values as follows:

	OK			success
	CBS_INVARG		invalid root name (no blanks)
	CBS_INVSIZ		invalid family size (database entry error)
	CBS_INVTYP		device is not a C475 module
	CBS_NO_SUCH		family device not found
	CBS_BUGCHK		invalid f(t) frequency found
	DIO_xxx			error retrieving database info

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, acnet_errors_h
