FUNCTIONAL DESCRIPTION:

IS200ACLEH1CAA is an Application Control Layer Module manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Application Control Layer Module (ACL) is a microprocessor-based master controller used to perform multiple duties over communication networks such as EthernetTM and ISBus. The ACL mounts in a standard Innovation Series drive or EX2100 exciter board rack and occupies two half-slots. The ACL and board rack are located in the control cabinet. In drive applications, the ACL P1 connector (4-row 128-pin) plugs into the Control Assembly Backplane Board (CABP). In the EX2100 exciter, the ACL mounts in the Exciter Backplane (EBKP). Optional hardware accessories are available. These items must be ordered separately from the ACL and include the following:

• Serial adapter cable (336A4929G1)
• Serial cable (336A3582P1)
• Primary features of the ACL core software include:
• Control blackware language and library
• Online application configuration loading
• I/O points and internal Booleans forcing
• Diagnostics for broken run/start permissions
• Application-level alarm messages
• Non-volatile flash memory
• Toolbox interface and support through Ethernet
• Application control for Innovation Series drives

HARDWARE FEATURES:

• Central processing unit (CPU)
• Peripheral component interconnect (PCI) controller
• 128 K byte level 2 cache
• 8 MB dynamic random access memory (DRAM)
• 4 MB flash memory basic input/output system (BIOS)
• Ethernet
• Bus target interface
• Serial ports COM1 and COM2
• ISBus communication ports

SOFTWARE FEATURES:

Basic Input/Output System (BIOS) identifies and initializes the hardware. During initialization, the BIOS directs all output display information to the COM1 serial port. The BIOS also supports serial loading of the operating system (compatible with the present GE loader) during the initial boot sequence through the COM1 port.

• Overwrites the boot interrupt to point to GE extended BIOS
• Displays the CMOS settings via the COM1 serial port (accessible through the toolbox and setup utility)
• Accommodates an RS-232C download
• Initializes any GE-specific hardware
• Resets the ACL_ through RESDRV when needed through an I/O write
• Enables flash disk support and booting.
• Overwrites INT 10 with calls to the serial interrupt.

FREQUENTLY ASKED QUESTIONS:

How does the ACL Module support communication?

The ACL supports Ethernet and ISBus communication to connect and manage different components within the control system, ensuring smooth data exchange between devices.

What is the role of the BIOS in the ACL Module?

The Basic Input/Output System (BIOS) initializes hardware during boot and supports serial loading of the operating system via the COM1 port. It also manages system settings and directs the display output through the serial port if a PC/104 VGA board is not present.

Where is the ACL Module mounted in the system?

The ACL Module mounts in either a standard Innovation Series drive rack or EX2100 exciter board rack, occupying two half-slots. In drive applications, it plugs into the Control Assembly Backplane Board (CABP), while in EX2100 exciters, it mounts in the Exciter Backplane (EBKP).
