The UC-100 (Unit
Controller - Model 100) is a self-contained microcomputer system based on the
housing system of the MAN
Roland interbus subassemblies. The UC-100 contains a powerpack unit,
microcomputer +
interfaces, interbus master subassembly and interbus interface module.
The computer has
the following main features:
1. The powerpack
units are electrically isolated DC-DC converters with 24VDC power supply.
During power-down the
SRAM memory of the microcomputer can be buffered through an integrated battery. The local INTERBUS has its own
powerpack unit.
2. The system CPU
is based on a MPC857T processor from the Power PC line of Motorola. It has
flash EPROM, SRAM,
SDRAM as memory media and a Compact Flash Card port.
3. The computer is
integrated in the overall press group through an Ethernet LAN network.
4. Other
interfaces are 2 x RS-232 and one RS-422 (RxD, TxD with Xon/Xoff protocol).
5. The
input/output subassemblies are coupled via field bus interfaces (INTERBUS remote bus and INTERBUS local bus). An INTERBUS master
subassembly including a bus terminal is integrated for this purpose.
For diagnostic
purposes an LCD diagnostic display as well as a diagnostic interface (RS232)
are
available.
