Control technology is at the heart of every system. It contributes significantly to optimised processes and movements as well as to higher cost efficiencies and improved productivity of the machine. Control technology is an essential part of an overall automation technology setup. It includes the design and implementation of the machine controller, i.e. the specific impact it has on the behaviour of pneumatic and electric systems. At Festo, we make a fundamental distinction between pneumatic and electropneumatic as well as electronic controllers.
Pneumatic and electropneumatic control units make designing logic sequences for pneumatic systems perfectly uncomplicated. Stepper modules are used in pneumatic applications to ensure a consistent program sequence. These are available from Festo as stepper module TAA or TAB. A stepper module chain consists of a certain number of command memory modules, also called double pilot valves. Our command memory module SBA-2N-PK-3 enables continuously recurring start, stop and holding functions to be linked, and can, of course, be combined with stepper modules TAA and TAB. The double pilot valves themselves are connected in such a way within the control technology that a switching step can only be triggered when it is actually needed. A stepper module is assigned to each individual step, thus creating a clear system structure at all times. The last component is the Festo pulse oscillator VLG, which can be used to generate infinitely adjustable signals in controllers. It is particularly suitable for fast movements with diaphragm cylinders as well as single- and double-acting cylinders.
Our electronic control technology consists of modern, compact and versatile programmable logic controllers. Different control systems are used in automation technology depending on the application area and industry. We currently offer electronic controller CECC, which enables programming with CODESYS according to IEC 61131-3. It has 12 digital inputs, 8 digital outputs as well as 2 high-speed counters up to 250 kHz. A USB interface enables the uncomplicated data transfer.
在电气外围设备方面，Festo 既可为特定的自动化系统提供模块和单个元件，也可提供整套自动化平台和控制系统。比如，Festo 产品系列中包含两款远程 I/O 系统：CPX-AP-A和CPX-AP-I。在自动化平台 (AP) 上，每个系统或者两个系统构成的组合，其每个总线接口最多可以自由组合 80 个模块或阀岛。可以选配包括 IO-Link 在内的诸多产品，用以通过双向通信轻松、直接地连接传感器，对传感器和其他设备进行广泛的诊断和编程。作为 Festo 核心系列产品的组成部分，现场总线模块 CTEU适用于阀岛 VTUG、MPA-L和VTOC。我们的其他外围元件可搭载集成式诊断和维护功能，配备模拟输入和输出模块以及高性能远程 I/O 系统等。而自动化系统CPX-E既可用作远程 I/O，也可与 CODESYS 控制器配套使用，用作执行运动控制任务的先进控制系统。理想的补足：IO-Link。
我们的人机界面设有“人机接口”(HMI) 用户接口，通过此接口可以操作机器、观察设备状态和干预控制过程。HMI 采集的信息通过可视化管理功能，在操作面板上显示，为人机界面的用户提供相关信息。某些 Festo 人机界面搭载诊断功能 (CDSB-A1)、远程访问功能 (CDPX)，或者装备与我们的机器人库相连的集成式报告系统和用户管理系统。
作为人机接口，人机界面 CDPX可为简单的可视化管理任务提供诸多功能，比如过程数据可视化或者通过 CODESYS、EtherCAT 和 Profinet 主站实现的复杂设备控制可视化等。作为防护等级达到 IP65 的防爆级产品，它是过程自动化的明智选择。
