PNU Description
11.72 Configuring the SIMOLINK board
U740 SLB Node address
(2740) Node address of the SIMOLINK board (SLB) on the bus. The node address
defines the telegrams to which the relevant board has write access. The
*
node address also defines whether a node is to perform the additional
function of dispatcher.
0 =
Not 0 =
Only one node in a SIMOLINK ring may perform the function of dispatcher.
Node address 0 may not be assigned to any node if a higher-level PLC is
performing the dispatcher function as the SIMOLINK master. When an SLB
is selected to operate as dispatcher, all nodes must be assigned
consecutive addresses, starting with address 0 for the dispatcher.
i001: For first SLB in unit
i002: Reserved
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
of U741.
0 = No telegram failure monitoring

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)
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.

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
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.
