For example, if you click the "Reference" button for the Off-Delay parameter of
an Off-Delay timer, you can then choose a specific block to reuse the time
value of that timer.
LOGO! 0BA7 and LOGO! 0BA8 devices provide a timer reference function. With this
function, you can take the current time (Ta) of a timer as the reference value (C) in other
function blocks. The calculation of the reference value (C) follows the formula as shown
below:
Current time (Ta)
Time base
Reference value (C)
A : B
Hours (h : m)
C = A × 60 + B
A : B
Minutes (m : s)
C = A × 60 + B
A : B
Seconds (s: 1/100s)
C = A × 100 + B
Protection
If a Protection Active check box exists for the protection of a block parameter, you can
enable or lock the display and editing of this parameter in LOGO! configuration mode.

The switching state and counter values of SFBs can be retentive. This means that the
current data values are retained, for example after a power failure, so that the function is

time-to-go expires.
You must set the retentivity to enable this feature for the relevant function. There are two
You must set the retentivity to enable this feature for the relevant function. There are two
possible settings:
● On: Current data values are retained.
● Off: Current data values are not retained (default).
The Hours counter (Page 249) is an exception, because it is always retentive.
