Page 6: Introduction
This manual provides the following information about the Microlok II system. • System level application and operational descriptions • System component specifications This manual is to be referred in conjunction with the Microlok II service manual SM6800A. 2.1. SYSTEM OVERVIEW The Microlok II system operation is controlled by proprietary executive software running on the system hardware.
Page 7: System Description
CAB/ Other Non-Vital application, Maintenance and Diagnostic function 4.1. MICROLOK II HARDWARE The Microlok II system consists of modular card file-mounted equipment and external peripheral devices that are used to interface the card file circuitry to the field gears and other associated control systems. The following sections provide an overview of the hardware.

19.6V DC to 32.4V DC 4.1.3. CARDFILE The Microlok II card file is a G64/96 bus based card file that holds the CPU, Power Supply & Variety of I/O boards. The card file will be a user configurable.
Page 9 The CPU board contains the central controlling logic and diagnostic monitoring for the Microlok II system, and provides five serial data ports. The CPU connector housing has an internal EEPROM that is used to store site-specific configuration data.

PCB is used for non-vital boards 4.1.9. KEYING PLUG Each of the Microlok II card file slots includes a 12-way female keying guide next to the 96-pin connector. The guide is used to ensure installation of the proper circuit board in each card file slot after the complete card file board configuration has been determined.

6.1. MICROLOK II SOFTWARE The primary Microlok II software components are the executive software, which is actually the Microlok II operating system software, as well as the application specific user-written software. Also included in the Microlok II software architecture is self-checking diagnostics designed to support fail- safe operational requirements.
Page 22: Application Software
Executive software that is continuously executed and controlled from the CPU board in order to detect and act upon various fault conditions. Microlok II uses diversity and self-checking concepts in which critical operations are performed in diverse ways using diverse software operations, and hardware is tested with self- checking operations.
Page 23: System Operating Modes
Critical Errors in the Microlok II system may be caused by persistent or transient faults. After a Critical Error has occurred, the Microlok II will be reset and will perform complete system diagnostics.

Developer. 9.1. LOGIC PROCESSING The Boolean logic processing within Microlok II will also be of the same type of relay emulation as the Microlok and Genisys logic processors. In addition to the basic Boolean logic, the system will include table processing and block processing.
Page 25 USSI Microlok II Functional description 10.1.1. SYSTEM EVENT LOG • The system event log records up to 5000 of the most recent critical errors, warnings, and events. When the log has reached its maximum limit, the newest errors will overwrite the oldest errors.
