3.12.4. I/O Card Rotary Address Switch
This screwdriver-adjustable switch is located on the I/O card(s) as shown in
and is set up for the card address (before the controller is powered up) in
accordance with the appropriate Works Specification. The valid address range is 1 through 9. Address
0 is the default address switch position for spare cards.
Important:
The address range is shared with the Intelligent Detector Backplane cards and must be unique.
The address range is limited to 1 to 9. Addresses 10 and above are used by the CTBs. Due to
architecture of Plus
+
this is not expected to be a practical limitation.

3.13. CPU I/O Card
The CPU I/O card is designed to provide an ‘integrated’ I/O capability for ‘smaller’ controllers. The card
is mounted onto the CPU Card as shown below and provides 24 inputs and 4 changeover outputs.
All Inputs and outputs are TOPAS 2523 compliant. LEDs and GSPI ports are as described above for
standard IO cards and the CPU IO card has a fixed address: 1.
May flash so fast that it looks like Green Steady.
