The IC660ELB906 is a Genius l/O IBM PC interface Module (PCIM),
which acts as an entry point into the Genius I/O System for the IBM
PC/AT/XT family. The PCIM is a motherboard/daughterboard designed
for user-developed microprocessor system integration. This PClM
provides a low cost ‘tap’ on the Genius I/O bus, allowing a host
system to control remote I/O utilizing extensive diagnostics, high
reliability, and noise immunity. The PClM software driver, a high
level interface between applications user-developed software and
the PCIM, provides bus access.
The IC660ELB906 PCIM’s daughterboard is a general purpose I/O
controller that provides a convenient method to control devices on
the Genius serial bus. The daughterboard performs initialization
and fault management tasks for up to 30 bus devices, stores
up-to-date images of the l/O controlled by each device, and is able
to communicate with other controllers on the bus by passing
background messages not associated with I/O commands. The interface
is optimized for the IBM personal computer bus. Network data rate
is configurable by an on-board dip switch, which allows the PCIM
daughterboard to handle protocol and provide a general purpose,
non-time critical method of tapping into the Genius twisted pair
network.
The IC660ELB906 PCIM’s motherboard provides a convenient way to interface an Open Architecture daughterboard to an IBM compatible host. All signals necessary to communicate with a daughterboard are buffered through the motherboard to the host bus. In addition to expected interface lines, the motherboard also provides daughterboard control and monitoring functions, including a standard ‘unit load’ to the IBM bus, low supply voltage detection, power-up RESET signal sequencing, and host system address decoding. A built-in timer can monitor system operation and shut down the daughterboard if the host system faults, which prevents potential conflicts on the bus. This timer can be user-disabled by way of a jumper.
The IC660ELB906 PC Interface Module or PCIM which is made by GE
Fanuc is made to be installed in an XT-type slot in a personal
computer. It is designed to interface a Genius bus to a compatible
host computer. It is also designed to integrate with user-developed
microprocessor systems.
This interface module has a cost-effective design, extensive
diagnostic facilities, and high level of reliability and noise
immunity, making it ideal for the Genius I/O system. The
IC660ELB906 PC Interface Module offers control and monitoring
functions such as low supply voltage detection, host system address
decoding, host interrupt control, signal conditioning, and a
built-in watchdog timer. It also provides an onboard DIP switch for
configuring the network data rate.
The IC660ELB906 PC Interface Module consists of a motherboard and a
daughterboard that are made to provide effective interfacing
facilities. The motherboard is a 2-layer rectangular board and the
daughterboard is a 4-layer rectangular board. Its functionalities
consist of 3 main sections which are the serial interface,
dual-port RAM, and PCIM manage processor.
The required data from the host computer is received into the input
table segment for the corresponding serial bus address of the bus
interface unit. In order to employ the I/O data of the bus
interface unit accurately, the module arrangement of the station
and information of the I/O data must be properly entered into the
host computer.
The I/O data includes the input and output details of the relevant
serial bus addresses for the bus interface modules. A personal
computer that is equipped with the IC660ELB906 PC Interface Module
can effectively control the field control station and Genius I/O
blocks that are in the same application system.
