5.5 2330 TX series control card
This card is the central controller for the TX500 system. It can be considered as a ‘PC on an
ICON card’, and runs a real-time operating system with the core program held in ‘flash’
memory on a pluggable chip. The controller system configuration is also written to the flash
memory, which may be backed up using a PC connected to the Ethernet port, see Section
10 of this manual. Communication to most other components in the system is via built-in
serial links, there are also 16 GPIs on the card. The interface to the automation system is
either via an RS422 or Ethernet connection. The following diagram shows the card
configuration switches and LEDs, most other components are not shown:
