SISTRADE reserves one of its business areas to technology solutions implementation of data acquisition, industrial supervision, planning and production control, which are called Sistrade® SCADA & Shop Floor Control, which could also be construed as an MES (Manufacturing Execution System).
SCADA (Supervisory Control and Data Acquisition) are software systems to monitor and supervise the data acquisition devices of various participants in the manufacturing process and may act in the field by controlling remote inputs/outputs or programmable logic controllers - PLCs.
Information systems Shop Floor Control oriented, is software that allows one to plan job orders on time, monitor real-time production process according to the preset routing, to control the movement of materials and hence make a production control more efficient. Here, SCADA turns out to be a complement to the management systems and production control.
ANALYSIS, DESIGN AND INSTALLATION OF INFRASTRUCTURE
In these projects SISTRADE presents complete solutions for data acquisition and process control, through the analysis phase of the factory layout and equipment to be controlled; design phase, where all the infrastructure of data communications to implement is specified, as well as the list of equipment to install; the last phase comes up to the job of installing and monitoring of the entire network confirms the survey made in the previous phase.
Having a wide experience in this area, SISTRADE provides various solutions, using the latest technologies, as is the case: terminals with Ethernet interface, wireless PDTs, use of laser barcode readers, installing touch-screen consoles, last generation automata, sensing equipment, RFID, etc.
In most projects, the data acquisition is based on the installation of collection points (industrial touch screen consoles + barcode reader + thermal printer) and in the installation of an automaton (PLC) to receive data directly from machines or production lines. The handling of these data is done in a collection server using Sistrade® ERP software.
PRODUCTION DATA COLLECTION VIA CONSOLE OR INDUSTRIAL PC
This system involves the placement of collection points, with the installation of industrial consoles (e.g. for groups of machines or for each machine), registered by barcode or by touch, the number of job orders, operations, incorporated materials, machine identifications, operator identifications (and other) and also the elements for quality control.
The information to be recorded in this equipment is as follows:
- Release of job orders (Start / End);
- Start / end of operations (productive activities);
- Allocation / de-commissioning of employees to certain machines;
- Start / End of the events (unproductive activities);
- Materials to be incorporated in the machine;
- Production Records;
- Quality Control tests.
For example, we present an interface of data collection, control and supervision of the machines.
PRODUCTION DATA COLLECTION VIA INDUSTRIAL AUTOMATION
To complement the data collection via console, SISTRADE recommends implementing a collection solution based on direct data acquisition through machines or PLCs. Whenever the machine or production line provides a communication port with known protocol, it is possible to configure Sistrade® ERP software to obtain and process the data that the machine delivers.
If it is not possible in this way, SISTRADE recommends installing a network of sensing equipment, machinery and production lines in order to receive data via automaton and make its treatment in the database server.
The proposed architecture typically involves the installation of a network master (CompoBus/D, compoNet or DeviceNet), from which a cable is extended with multiple input cards/digital outputs /analogues. Each of these cards will connect a group of machines. The cards are placed in a strategic place to minimize cable distance. In each machine a box of centralizing signals is placed, to facilitate eventual transport, movement of the machinery or modification of signals.
Example of setting up a network called CompoNet.
The information that may be obtained from this collection is as follows:
- Functional status of the machine;
- Instantaneous speed;
- Average speed;
- Produced Quantity;
- Time of adjustment and production;
- Time of stops;
- Reasons of stops;
- Consumed quantity (according to the produced quantity, the system can calculate the incorporated amount of raw material or semi-manufactured, for the incorporation of previously defined factors);
- Other signal that can be relevant.
SCADA – INDUSTRIAL SUPERVISION
Sistrade® software SCADA (Supervision Control and Data Acquisition) is a fully customizable tool to suit each plant layout, multi factory, supports various sections and any type of resource, either a machine, a production line or a manual resource with human support. Its main objective is graphical monitoring of the production status as well as the operating status of each resource.
Through synoptic panels, each of the processes can be monitored. These panels are designed using Sistrade® Layout and then run on Sistrade® Supervision. The results can be displayed with icons and colour effect, and their representation is in agreement with the data collection on the shop floor.
In terms of features we highlight:
- Local or remote supervision, multi-factory;
- Actual information of the status of the machine operation;
- Identification of employees who are working on the machine;
- Production order that is in progress;

PRODUCTION PLANNING (SCHEDULING)
In order to assist the production manager in planning job orders and meeting delivery deadlines, SISTRADE offers its customers a tool capable of planning production operations. Sistrade® ERP software for production planning is a system of decision support in the planning of job orders, allowing allocation of operations resources over a given time frame. The sequencing of activities depends on the priority criteria previously set and aon the capacity of each resource.
- Master plan of production;
- Scheduling of the JOs and/or orders;
- Visualization of job orders on GANTT chart;
- Report of charges in tabular or graphical format;
- Simulation of different scenarios;
- Task scheduling;
- Drag-and-drop operations on GANTT chart;
- Setting time of operations;
- Subcontracting a particular activity;
- Dynamic planning with indexing to the beginnings/ends and delays in production;
- Synchronized with the production data collection.
This module provides Wizard of assisted planning of job orders that enables:
- Selection of production orders or job orders to plan;
- Criteria selection for scheduling and sequencing of activities;
- Suggestion of a more appropriate workcenter to perform the work, according to the planned sequence of operations/activities, also allowing the user to select another workcenter, one considers most appropriate for the job;
- Suggestion of the workcenter to perform the task allows, if desired, people responsible for planning to divide the work between several workcenters;
- Suggestion of an optimal sequence for work orders execution, allowing people responsible for planning to change the sequence according to what they consider as relevant.
GANTT/ ANALYTIC CONSULTATION OF PLANNED JOB
Sometimes the shop floor control requires to record tests and quality parameters. For this reason, Sistrade® software allows parameterizing a set of measurable and visual parameters for quality control during the production process. For each test it is possible to define tolerance intervals, so that when the user indicates the value, the system validates whether it is inside or outside the allowable range. Associated with this process, Sistrade® system can issue quality labels or certificates to highlight the results of the tests and the product is conformable or non-conformable. Treatment of waste is also a part of quality control. At any time and at any manufacturing stage, the user can register an inherent waste in job order.
Features that we consider the most interesting:
- Configuration of quality parameters, according to the type of process;
- Definition of tolerance intervals in absolute or percent value
- User-friendly interface for quality records;
- History of quality control;
- Quality Certificates;
- User identification, date, time in which the test was done;
- Interface optimized for touch screen and portable data terminal;
- Possibility of connection to measurement equipment.
The system provides a set of statistics, such as:
- Analysis of waste per shift and per job order;
- Records of non-conformities per shift, per machine and JO;
- Graphic analysis of defects;
- Statistics of reclassified products;
MANAGEMENT OF RAW MATERIALS
As part of the monitoring system and SISTRADE production steering, comes the management of raw materials with the definition of product trees, formulation, manual and automatic consumption conform factors for incorporation. The system has interfaces that allow the "shop floor" to define the formulation of a given production process. Through the selection of raw materials, lots and incorporation factors, it is possible to change in the collection interface, the standard formulation that is defined in the job order. The output of stock or raw materials or semi manufactured, may be made by manual registration, reading the bar code of the lot and introducing quantity or by automatic output to the quantities produced. Whenever there is a production record, the system may terminate the stock of raw materials in the amount proportional to the factor of incorporation.
Relevant features of this process:
- Multi-level definition of product trees;
- Manual consumption with reading of bar code;
- Automatic consumption based on the quantities produced;
- Pre-confirmation of the outputs of stock;
- Definition of the formulation with the beginning of the JO;
- Instantaneous consumption per machine and per shift;
- Various alerts for placement of raw materials per JO and per machinery.
FORMULATION, MANUAL AND AUTOMATIC CONSUMPTION OF RAW MATERIALS
The registration of products in SISTRADE shop floor control system can be done by the operator in collection console or automatically by order of the PLC (automaton) that sensitizes the machinery. In practical terms, if we have a sensor, a photocell or any other signal that the machine makes available that could be perceived as a signal that something was produced, SISTRADE interprets this signal and causes the production record in the database according to the elements that were registered in the console, including the job order, and operations and employee who are working on the machine.
Sistrade® ERP software also allows connection to measuring equipment for measuring the recorded values, for example, the output of a machine or section may be placed on a balance for the system to record automatically the actual weight of product produced.
In terms of identification, SISTRADE provides labels that can be bar coded or RFID for raw materials, semi-manufactured and finished products. It is also possible to define labels to track pallets or sets of boxes.
Relevant features of this process:
- Registration of produced quantities in the industrial console;
- Registration produced quantities via industrial automation;
- Calculation of production using a function of production time or speed;
- Connecting equipment weighing to determine actual weights;
- Productions in two measuring units (e.g. meters and kilograms);
- Traceability of the production process.
