PNU Description
U741 SLB Telegram failure time
(2741) The telegram failure time defines the period within which a valid
synchronizing telegram (SYNC telegram) must be received. Failure of any
*
SYNC telegram to arrive within the set period indicates a communications
error. The unit activates fault message F015 (see also U753) as a function
(Z121)
of U741.
0 = No telegram failure monitoring
i001: For first SLB in unit
i002: Reserved
U742 SLB Transmitter power
(2742) Setting of power of fiber optic transmitter
*
1 = 0m to 15m (length of plastic fiber optic cable)
2 = 15m to 25m (length of plastic fiber optic cable)
(Z121)
3 = 25m to 40m (length of plastic fiber optic cable)
Operation at a lower transmitter power increases the service life of the
transmitter and receiver modules. Reducing the transmitter power also
allows hidden fault sources on the transmission path (e.g. poor contacts on
fiber optics) to be detected.
i001: For first SLB in unit
i002: Reserved
U744 SLB Selection of active SLB board
(2744) Selection of the active SIMOLINK board (SLB) when two SLBs are installed
in one unit.
*
0 = binector B0000
(Z121)
1 = Binector B0001 etc.
A binector value of 0 means "SLB in low slot is active".
A binector value of 1 is reserved for "SLB in high slot is active".
U745 SLB No. of channels
(2745) Number of channels which dispatcher provides for each transceiver.
Together with U746, the number of channels determines the number of
*
addressable nodes.
This parameter is relevant only for the dispatcher.
(Z121)
i001: For first SLB in unit
i002: Reserved
U746 SLB Cycle time
(2746) The cycle time is the period required for all telegrams to be passed around
the SIMOLINK ring. Together with U745, the cycle time determines the
*
number of addressable nodes.
This parameter is relevant only for the dispatcher.
(Z121)
i001: For first SLB in unit
i002: Reserved
NOTICE!
The values 0.20ms to 0.99ms are reserved and must not be set here.
n748 SLB Diagnosis
(2748) Visualization parameter which displays diagnostic information for an
installed SIMOLINK board (SLB)
(Z121)
i001: Number of error-free synchronizing telegrams
i002: Number of CRC errors
i003: Number of timeout errors
i004: Last accessible bus address
i005: Address of node sending the special telegram "Timeout"
i006: Implemented bus cycle time
i007: Number of new configurations
i008: Reserved
...
i016: Reserved
