♦ B0047: SLB2 timeout (only MC)
Bit = 1 indicates that a timeout has been detected on the passive
SIMOLINK bus.
♦ B0048: SLB2 start (only MC)
Bit = 1 indicates that the passive SIMOLINK ring is physically open
and a start cannot be carried out. This binector corresponds to
alarm A004.
♦ r748: SLB diagnostics
The diagnostic parameter is used to retrieve various status data of
the SIMOLINK bus. The following information can be read from the
various indices:
r748.1: Number of error-free SYNC telegrams (corresponds to the
bus cycles that have elapsed without error).
r748.2: Number of CRC errors (telegrams with errors).
r748.3: Number of timeout errors (bus interrupt). Note: On bus
initialization, data traffic is interrupted several times,
causing some timeout errors.
r748.4: (Dispatcher only) last addressable address; on initialization
the last address addressable in the selected configuration
is entered here.
r748.5: Address of the station that has signaled timeout.
r748.6: Here, the hardware interrupt delay is stored that was
calculated from the number of stations set (P743), or from
the number of stations transferred during initialization (with
automatic parameterization P743 = 0), and the position of
the station in the SLB ring.
r748.7: Position of the station in the SLB ring (result of the count
during initialization).
r748.8: Number of stations in the SLB ring (result of the count
during initialization).
r748.9: (MASTERDRIVES MC) deviation from the synchronization
point. Cannot be synchronized, the value is set to
NO_SYNCHRONIZATION (= 65535). Should not fluctuate
outside 65515 (-20) and 20.
r748.10: Pulse period adapted to the bus cycle time in 100 ns
(e.g. pulse frequency 5kHz → display value 2000). If no
synchronization is possible, the value
NO_SYNCHRONIZATION (= 65535) is entered.
r748.11: Current state of the T0 counter. Should be 0 for active
synchronization (MASTERDRIVES MC only).
r748.14: Current state of the time slice counter.
Should be 0 for active synchronization (MASTERDRIVES
MC only).
r748.15: Bus cycle time implemented in 10 μs.
r748.16: Bus cycle time transmitted during initialization from the
master/dispatcher in 10μs.
