The SIMOLINK Encoder does not output any pulses when the supply
voltage has been connected; instead, the SIMOLINK data interface
waits for the SIMOLINK ring connection to be established.
In every cycle, the encoder receives a setpoint with control bit in a 32-
bit telegram via the SIMOLINK data interface and returns its actual
value with status bit in a 32-bit telegram via the same route.
The setpoint telegram is defined by means of the receive channel and
address set on DIL switches S1 and S2 (cf. Section
DP both of these values can be altered via the PROFIBUS interface (cf.
Section 6.4). The actual-value telegram is defined by the SIMOLINK
node address = transmit address of the SIMOLINK Encoder, as well as
the permanently set transmit channel '0'.
To ensure that the SIMOLINK Encoder can operate in the SIMOLINK
ring, the cycle time in SIMOLINK dispatcher mode must be 1.6 or
3.2 ms, i.e. exactly 251 telegrams for one SIMOLINK cycle of
approximately 1.6 ms or exactly 503 telegrams for one SIMOLINK cycle
of approximately 3.2 ms. The SYNC LED illuminates continuously only
if one of these two cycle times is selected and only then is the encoder
ready to operate.
The SYNC LED flashes if a cycle time other than the two above is
selected (flashing frequency about 2 Hz, Z-PULSE LED remains off).
When a cycle other than 1.6 / 3.2 ms is selected, the encoder will not
output any pulses, even if it is correctly activated, and the bit 'SLE
status' in the SIMOLINK actual-value telegram remains inactive at '0'.
