5.7.7 Direct mode: Continuous setpoint specification (Continuous mode)
With continuous setpoint specification (Following mode) the
higher level controller continuously specifies position values
at fixed time intervals (typically 4 ... 10ms). Since this time
interval is usually longer than a position controller cycle
(350s, the controller independently interpolates the values
between the specified position values. At every specified
interval, the CDIR.B4 CONTT (Toggle
Bit") must be toggled to
ensure that any new interval is recognised.
