GE IS200ACLEH1ACB Application Control Layer Module (ACLE)

Product Overview

The IS200ACLEH1ACB is an Application Control Layer Module (ACLE) manufactured by General Electric for the EX2100 control systems. This microprocessor-based master controller manages various tasks over communication networks such as Ethernet™ and ISBus. It fits into two half-slots within a standard Innovation Series drive or EX2100 exciter board rack, offering robust control and communication capabilities.

Hardware Features

Integrated Circuit Features

Central Processing Unit (CPU): 486 processor running at 100 MHz with a 16 K byte internal L1 cache.
Memory:
- 8 MB Dynamic Random Access Memory (DRAM)
- 4 MB Flash memory for the Basic I/O System (BIOS)
- 128 Kbytes Level 2 (L2) Cache
Connectivity:
- High-speed Ethernet and ISBus communication ports

PCI Controller

Manages memory, I/O, and configuration transfers to/from the PCI bus.
Facilitates 152 ns cache line fills between L2 and L1 caches.

BIOS (Basic Input/Output System)

1 MB (128 KB x 8) flash memory device mounted in an ACL socket.
Supports redirection of video display to COM1 if no VGA board is installed.

PCI/ISA Bridge

Connects to the CPU via the Address and LINK buses.
Manages system clock, reset logic, keyboard, speaker control, and advanced power management.

Software Features

BIOS Initialization: Identifies hardware and directs output display to COM1.
GE Extended BIOS:
- Supports serial loading of the operating system via COM1.
- Displays CMOS settings and supports RS-232C downloads.
- Manages specific hardware initialization and enables flash disk support.

GE Control Systems Toolbox

Configures runtime actions and stores application code as Pcode in memory.
Allows online monitoring, parameter changes, and firmware upgrades over Ethernet.
Uses Serial Loader for operating system upgrades and configuring TCP/IP addresses.

Connector Pin Signals

The ACL faceplate includes user connectors for communication and control interfaces:

COM1/2 Serial Ports: Provide serial communication interfaces.
P3 Ethernet Interface Connector: Facilitates high-speed network connections.
ISBus Connectors: Enable robust communication with the control system.
