Smart Trac CPU Card
General Capabilities
The Smart Trac CPU card permits a Smart Trac AC1 to be quickly programmed
for custom applications using IEC-61131-3 languages. These languages include
Relay Ladder Logic (RLL), Sequential Function Charts (SFC), Function Block
(FB) diagrams, Structured Text (ST), Instruction List (IL) and function blocks
written in the C programming language. It also provides for easily expanded
communications and/or extra Input/Output capabilities.
The card executes user's programs, provides the interface between the digital
operator and the rest of the Smart Trac AC1, and communicates with other
computers for download, upload and monitoring of programs and data. It
connects to cards conforming to the PC/104 Specification. Several cards,
including option cards, may be added to interact with the Smart Trac CPU card
including: the Smart Trac PG card; Smart Trac Ethernet, Smart Trac LAN,
DeviceNet, Genius PCIM, Modbus, Profi-bus communications cards; and the
Smart Trac Multi-I/O card.
All option cards conform to the PC/104 Specification, Version 2.1. They stack
with the Smart Trac CPU card using its PC/104 expansion bus connector. The
Smart Trac CPU conforms to the PC/104 expansion bus.
