status.i4.v = wg_ft_frequency(main_device.i1a.r, ft_freq.i4.r)

	This routine returns the time table update frequency for a
	C465/6/7/8/0, C453, C473, V473, or C475 module.

	main_device	name of base (no suffix) device
	ft_freq		returned f(t) frequency in Hz

	This function returns status values as follows:

	OK			success
	CBS_INVARG		invalid root name (no blanks) or event
	CBS_INVSIZ		invalid family size (database entry error)
	CBS_INVTYP		device is not a C465/6/7/8/0, C453, C473,
				V473, or C475 module
	CBS_NO_SUCH		version or family device not found
	negative value		other ACNET error

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, tclk_events_h, acnet_errors_h
