3.8.6 Special Marker Area
The markers of 1 ... 65 are occupied by the system; the markers of 66 ... 99 are re-
served by the system for a subsequent use. Their meaning is given in the following for
the valency of 1. The opposite meaning is then valid for the valency of 0. The remain-
ing markers of 100 ... 10 000 are freely available for the user.

Marker Meaning
1 Starting signal (after original start / restart for a loop = 1)
2 0.3125 Hz flash
3 0.625 Hz flash
41.25Hzflash
5 2.5 Hz flash
6 5.0 Hz flash
7 Initial state of the sensor bit monitoring
8 Starting characteristics of the program (0 = restart, 1 = original start);

15 (free)
16 (free)
17 (free)
18 Loading system variables (= 1: no valid data in segment 16)
19 Loading system variables (= 1: automatic SYRES has taken place)
20 Error in the signal check loop (PEAB plug-in check; this is not carried out
by the ALU 061; error message can be suppressed by jumpering C10
and C12 pins on the UKA 024 or LI and LO ports on the ALU 011) since the original start
21 PEAB time error (e.g., through the failure of a peripheral power supply) since the original start
22 Access temperature on UKA 024 or ALU 061 since the original start
23 Battery undervoltage when the device is switched on (HE or RESET) since the original start
24 (free)
25 SEA parity since the original start
26 with ALU 150: UKA 024 is faulty or missing since the original start
27 Group error of Dolog blocks since the original start
28 Undervoltage of the rechargable battery since the original start

30 Error in signal check loop (PEAB plug-in checck is not carried out by
the ALU 061; error message can be suppressed by jumpering since restart
C10 and C12 pins on the UKA 024 or LI and LO ports on the ALU 011)
31 PEAB time error (e.g., through the failure of a peripheral power supply) since restart
32 Access temperature on UKA 024 or ALU 061 since restart
33 Battery undervoltage when the device is switched on (HE or RESET) since restart
34 (free)
35 (free)
36 with ALU 150: UKA 024 is faulty or missing since restart

41 Communication: telegram format error
42 Communication: transmit initialization. Transmits all the configured
logical message numbers, if, however, not to be set
43 Communication: transmit disable
44 Communication: receive disable
