During 2009 there was an increase in volume and expansion of production as a consequence the capacity expansion of the company ZOF ELECTRO. We provided 2 new jobs in positions of production, testing and service. We provided a set of special tools for production and expanded the capacity of the service. Made the reorganization of management within the company.



Production of concrete pipes machine controller is realized due to the failrue of operation of the original controller. Mechanical assemblies and machine drive has been completely preserved and as such was suitable for the application of modern automatization concepts.
The controller is implemented through development of four modules - basicly to optimize the management and "covering" all the required functionality.



Complete controller consists of four sub-controllers:

1. Central control mode

2. keyboard controller

3. Actuator controller (output block)

4. Sensor controller (input block)

Central control module synchronizes the operation of other modules and it executes an algorithm that describes the functionality required.

Keyboard controller performs continuous scanning Keyboard matrix and forwards the information of key pressed to the central control module.

Actuator controller maintains state of the output relays based on information from the central control module.

Sensor controller scans all the sensors (inductive and microswitch) and status of sensors forwards the central control module.

All parameters of automatic operation as well as all the manual controls are entered via the control panel and alphanumeric display 4x20 characters.
