Industrial 14 Software Manual

This document serves as the software manual for the Digital Equipment Corporation Industrial 14 controller family, designed for machine and process control. It offers comprehensive guidance on programming the Industrial 14 using a suite of PDP-8 based software tools.

The manual introduces the core programming concepts, including:

• Industrial 14 Programming: How to represent control functions using Boolean equations, circuit diagrams, or machine language, emphasizing advantages over traditional relay logic. It outlines input, output, and internal function organization.
• Basic Instructions: Details the fundamental test, set, and jump instructions, memory organization (octal addressing, fields, and pages), and the use of conditional, unconditional, and subroutine jumps.
• Internal Functions: Explores specialized internal functions such as retentive memories, shift registers, timers, and various types of counters, providing their configuration and application within control logic.
• Software Tools: Provides in-depth descriptions and operational instructions for BOOL-143 (Boolean equation compiler), SET-143 (symbolic equation translator/preprocessor), PAL-143 (program assembly language assembler), and ODP-143 (online debugging program). This includes their syntax, control statements, error handling, and optimization.
• PDP-8 Operations: Guides users through the procedures for operating the PDP-8 computer, including loading programs, using the Text Editor for source program composition and updating, and managing program files within the OS/8 system.
• Monitoring: Explains how the Industrial 14 communicates with an external computer, detailing dual interface ports, specific instructions for reading/writing memory and I/O states, and different monitoring approaches like status reporting and polling.

The document aims to equip control engineers with the necessary knowledge to develop, debug, and maintain Industrial 14 control programs, including considerations for VT14 programming terminal compatibility.
