Improvement of PLC in the production of objective management board

1, preface, is now a lot of workshop production management by objectives plate in the management of the production of the production line, can be directly set production goals, dynamic display their achievements in practical production. Intuitive to target with the current production control; More can promote the process of production. Due to the management board control is relatively simple, so basically are accomplished by single chip microcomputer. But in a factory environment, often there are a lot of interfering signal, lead to can't work normally, the stability of the management board. This will be a direct impact to production. So, in order to improve the reliability of products, adopting PLC to control, to effectively improve the stability of the management board. 2, the traditional production management board description of traditional production target management board is used to display a large panel, integrated single-chip microcomputer control circuit, LED display. As well as the operating handles. Usually adopts the suspension method. While operating the handle is used to set the related parameters, such as production target number, the timer time as well as the start of the management board and so on. And the count signal is provided by the production line of related sensors commonly. Common operation mode are pure button, or key combination dial the code switch. In the dial the code switch Settings is convenient, more convenient, intuitive operation. Currently has a production and management board as follow: using button for parameter setting, 【 Setting 】 、【 Choose a 】 、【 + 1. And the 1 】 The target button: 【 Target reset 】 、【 Target pause 】 Actual number button: 【 Performance reset 】 , and connection line of the Performance + 1] Switch input. Set the production management process is as follows ': according to the flowchart, system parameter setting is mainly through the buttons to operate. Steps seem complicated. Set speed is relatively slow. To a certain extent restricts the production efficiency. And if the management of the single-chip microcomputer control board in the production of systematic centralized management, it is difficult to data, so that the ERP management center for data collection, etc. So, to provide the stability of the system, management mode and adapt to the current factory, its reform is imperative. Now for motor FBs series PLC of Taiwan to modify it. PLC providing dedicated module FBs - LED display control 7 sg1/2。 Provides for the modification of the production management board is quite convenient conditions, no matter from wiring and control mode, are greatly simplified, thus can improve the stability and reliability of the system more convenience and control. 3, PLC hardware configuration according to the system configuration, control system are concentrated in two switch input and LED display unit. Given the late system upgrades, such as communicates with the has yet to do production data collection, simply add a communication board can be realized. So when choosing PLC, select the economical host FBs - MA series, the PLC host minimum points to 10 points, up to 60 points; But due to the LED to extension module must be used to achieve control output, the band extension module host for at least 20 points, so choose to FBs - here 20 ma host. ( The host is introduced in detail, please refer to the manual related products of the company) 。 The host for the input and output at 8 o 'clock 12; Communication can be extended to three mouth, bringing a programming port. To introduce the following key FBs - LED by the PLC controller output module 7 sg1/2。 的边后卫, 7 there are 7 sg1 sg and 7 sg2 two kinds of models, their internal respectively have one or two may show eight number seven segment digital tube or four 16 segment digital tube, below is the FBs - 7 sg2 sketch as an example.
