The job consisted of the automation of  3 distributed plants in Challacó - Baguales oil field(Neuquén): Injection Plant, Crude treatment Plant y Aguada Baguales Filtrate Plant.

The control systems was implemented with MicroLogix 1500 controller of Allen-Bradley, with scalable capabilities, anticipating a future radial expand of the systems. Input/output analogical and digital modules were used.

As a remote control system, field cabinets with PanelView 300 (Allen-Bradley) screens were installed. We built  the system to be able to generate alarms and storage historical report for events.

The work consisted in provision, installation and starting up of hardware equipment and software for the automation of the new station of pre-cure of cloacae remainders (EPN) on Puerto Madryn city (Chubut). Whit this infrastructure the unloading from remainders to the sea is avoided, taking advantage of them previous treatment, for fertilization and irrigation of the barren zones bordering to the city. The control system extended until the transforming station Derbes, because the important energy consumption of the plant.

Both nodes were integrated to the existing control system for Madryn - Trelew aqueduct. The system is implemented by remote stations with CPUs Motorola MOSCAD 400 series, communicated between it by radio links in UHF, covering several kilometers. The visualization points use software SCADA Wizcon, Version 7.6.

Alas Ingenieria replaced the previous control system (PlantScape of Honeywell) by the current DeltaV, of the Fisher-Rosemount, given the advanced characteristic of this equipment in process control. The system includes three main boilers plus the auxiliary (who works like boiler of recovery), that is destined to generate steam that is used, among other uses, to impel the turbines of the generators in order to supply energy to all TGS site in General Cerri (Bahia Blanca).

The system architecture consist of a workstation and a node in the control room Etano and another node in the auxiliary boiler control room. Each boiler has a independent controller. The system has redundant communication and uses Ethernet protocol, using optical fiber like physic layer for the greater distances to cover. In addition a bond to the system of existent Wonderware supervision settled down through a PLC Allen- Bradley using the facilities of OPC of DeltaV system. 

The solution consisted in remote command and supervising of the more important transforming substations of the Bahia Blanca city. The remote ones are implemented with Allen-Bradley PLCs and they communicate by a radio link with a central node located in the Operative Center of EDES, in which, by means of the HMI RSView32 (Rockwell Software) appear the data of current, tension and state of the switches of each substation appear. It is possible in addition to command the main switches of each substation to carry out fast and effective maneuvers.

In order to assure that each remote reports the present state before possible faults of energy within the substation was equipment each with a UPS able to feed the RTU and to drive relay of commando of the switches. With this, it is possible to operate remotely each substation before faults critics or unexpected events.

The central node allows  configuration of the levels of alarms, facility to the operator the verification and configuration of the same ones. The system login events and alarms in historical, for its later consultation.
