A Method for Implementing Microprocessor-Controlled Systems

Data acquisition and command system for use with a microprocessor-based control chassis. [PIGMI-Pion Generation for Medical Irradiations]

“…The program uses the monitor loop and MPC front panel described in Ref. 1. The program's main task is in the subroutine SETTM, which reads the delay time in decimal units from the hex switch, converts it to a binary number, and stores it in the timer.…”

“…The small inexpensive boards can be mounted near the 1 controlled device for one-of-a-kind applications. This is especially desirable for the analog part of a system because the interface to the processor is much less susceptible to noise than are the low-level analog signals.…”

General-purpose microprocessor-based control chassis

“…The basic arrangement of the crate is described in Ref. 1. The position of the crate allows access to the boards from behind the MPC.…”

“…Their value in accelerator control was sensed early at the Fermi National Accelerator Laboratory (FNAL) where an extremely adaptable, modular microprocessor-based controller was conceived. 1 The main advantages of the controller are its modularity and interfaceability. For example, one 115-by 165-mm board haB 64 binary data lines and 16 handshake lines.…”

“…Although in this report we describe a system-type controller, the modules can be used in smaller configurations for dedicated applications and/or single installations. 1…”
