6.3.3 Data format of actual-value telegram
The 32-bit actual-value telegram contains the momentary 15-bit actual
pulse output value, a status bit plus an internal counter value.

Bit Designation Meaning
31…17 Momentary
actual value
Momentary 15-bit actual value:
0…32767 corresponds to an encoder revolution of 0…360° or 8192 output
pulses (4096, 2048 and 1024 can also be set on the SIMOLINK Encoder);
the zero pulse is output on transition from 32767 to 0
16 - Unused: Preset to '0'
15…01 Setpoint reached Assigned to internal counter:
Setpoint reached by the SIMOLINK Encoder
00 SLE status Status feedback of SIMOLINK Encoder:
'SLE status' = 0
SIMOLINK Encoder is not outputting pulses (not started)
'SLE status' = 0 and 'SLE control' = 1
Activation error: SIMOLINK Encoder has
not been activated via DIL switch S1.5 or
has not been activated via PROFIBUS in the case of SLE-DP or
is indicating an error or
receive telegram set for the SIMOLINK Encoder does not match the setpoint
telegram
'SLE status' = 1
SIMOLINK Encoder is active and outputting pulses
Table 6-8 Meaning of SIMOLINK actual-value telegram
The actual position value that can be read from the SIMOLINK Encoder
is affected by a SIMOLINK-dependent time delay.
