XP860018 s Getting Started
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 Ad-
dresses, and Chapter 4, Software Reference, provide
detailson 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
twoboards have the same address, communication problems
will occur that may go undetected by the controller.
XP8600 expansion boards are shipped from the factory with no pins on
header J3 connected. Each XP8600 can have one of eight different PALs.
There are eight different ways to configure the three pairs of pins on
header J3, and so up to 64 different logical XP8600 addresses are possible
for a single PLCBus.
See Chapter 4, Software Reference, for further details on
how to determine the physical address for XP8600 expansion
boards based on which pins on header J3 are connected.
