4. Each expansion board comes with a factory-default board address. If
more than one expansion board of each type is to be used, be sure to set
a unique address for each board.
The following section on Setting Expansion Board Addresses,
and Chapter 8, Software Reference, provide details on how
to set and use expansion board addresses.
5. Power may be applied to the controller once the controller and the
expansion boards are properly connected using the PLCBus ribbon
cable.
See Appendix D, Simulated PLCBus Connections, for
details on the special connections that enable these expansion
boards to be used with the BL1000, BL1100, BL1400, and
BL1500 controllers.
Setting Expansion Board Addresses
Z-World has established an addressing scheme for the PLCBus on its
controllers to allow multiple expansion boards to be connected to a
controller.
Remember that each expansion board must have a unique
PLCBus address if multiple boards are to be connected. If two
boards have the same address, communication problems will
occur that may go undetected by the controller.
Every XP8900 Series board is shipped from the factory with a default
address of 7. An XP8900 Series board may be assigned any address
between 0 and 7 using jumpers on the pins of header P3 to configure the
board address. Figure 6-3 shows the jumper settings to set addresses 07.
A maximum of eight XP8900 Series boards may be addressed by a
controller at one time.
Pins 12 on header P3 are on the lower end of P3 when the
XP8900 board is oriented in line with a controller and other
expansion boards as shown in Figure 6-2.
