Traditional Configurations

 

Single ATLAS-XP2 Microcomputer

 

Single ATLAS XP2

The ATLAS system consists of a single rack that includes one microcomputer control board ATLAS-XP2 (usually, but not mandatory, located in the slot #1) and up to 13 PI modules of any type.  The only additional component that cannot be avoided is PSU - the power supply unit, which directly supplies the ATLAS-XP2 module, and through that module the whole PI rack.

 

Dual ATLAS-XP2 Microcomputer

 

Dual ATLAS-XP2

This is a version of the high-availability system configuration.   The central control component, a micro-computer ATLAS-XP2, is doubled and configured to work in a master/slave mode.  Usually, two microcomputer modules are taking first two slots in the rack (what is not mandatory), leaving remaining 12 slots available for PI modules of any type.  The external communication is provided via TCP/IP network interface and underlying LAN, and it is also redundant.  Same is valid for the power supply units.

 

ATLAS-MAX/RTL – Industrial Process Computer

 

ATLAS Industrial PC

The central computing unit ATLAS-CCU (industrial version) controls one or more PI racks containing PI modules of any type.  In this example two PI racks are mutually connected with daisy-chained PI signal cables, as well as with ATLAS-CCU unit that also provides external modem and network connections.  This is the most common ATLAS-MAX configuration, which has found wide implementation in practice.  It represents the best trade-off between system performance and price, and fits successfully in “an average process control system”.

 

ATLAS-MAX/RTL – High Availability Solution

 

ATLAS High Availability

A high availability ATLAS-MAX configuration is presented.  This is a fully redundant system, where major critical system components: power supply units and central computing units, are doubled.  The redundant hardware configuration is followed by a redundant firmware that provides an automatic system failover.  Usually, the master/slave approach is in place: a master CCU is active, while the slave CCU remains passive in the sync with the master.  Once a failure occurs, roles are changed.
