Summary
The 2A technology application
A collection of technical solutions and rules
for optimization of the process of industrial
control systems development


The 2A technology features


The platform consists of two parts:
 CANopen hardware, real-time based system
 2AConf software for system assembling,
configuring and calibrating
A real-time system developer is enabled to:
 Assemble system from various devices
 Install and calibrate sensors
 Install calculated parameters generators
 Configure presentation devices
 Tune up control logic
 Configure registration mode

Sensors are connected via ready-made unified digital
adapters
Any standard sensor (4…20mA or 0…10V) can be linked in a
minute
Special digital adapters for non-standard sensors can be
manufactured within the period from one to three months
Parameter registration rate: up to 1000Hz
2AConf software describes, configures and calibrates the
sensors in a system:


Choose a sensor’s type, e.g. Current sensor
Set a parameter name, e.g. Oil temperature
Set a parameter unit of measurement, e.g. Celsius
Set a parameter rate, e.g. 10Hz

Supports eight input and eight output parameters
Calculates simple expressions: sin, cos, atan, exp, abs,
ceil, floor, sinh, cosh, tanh, ln, deg2rad, rad2deg, sign,
pi, +, -, *, /
Computes logic predicates: <, <=, >, >=, ==, !=, put, get,
skip
Any special purpose logical controller device can be
manufactured within one month
Third party CANopen logical controller devices are

1. Real-time system
2. All devices share the same
address space on a CAN-bus.
The update time is about 1
msec.
3. Devices interact in accordance
with CANopen standard.
4. Devices have access to each
other and operate
independently in compliance
with embedded program logic.
5. Large scale systems with
complex control logic can be
assembled from simple 2Adevices with simple logic
embedded.
6. Cold start time is about one
second.
