ABB PM783F 可编程逻辑控制器

详细说明:中央处理器(CPU)模块配备了高性能处理器，可实现快速循环时间。它配有板载100 Mbit/s以太网连接,用于控制器、操作员站和工程工  之间的通信。两个串行线路接口完成连接。

-个接口可用于Modbus通信，而另-个用于诊断。CPU有10 MB的内存，其中2 MB是备用电池。对  于要求苛刻的应用，可以配置八个周期时间可调的循环和优先级驱动任务，以吸-一个尽可能快速运行的循环PLC类型任务。小型前面板显示器直接在  模块上显示状态和诊断信息。

此外，您可以通过按键锁定控制器。这意味着可以阻止控制器下载应用程序和固件，以增强安全性。如果控制器锁定或  解锁，状态将显示在显示屏上。S700 I/O模块可以直接插入CPU模块,也可以通过PROFIBUS用作远程I/O。- -个控制器最多可以连接八个模块。第  三方I/O可通过MODBUS ASCI / RTU、IEC 60870-5-101遥控协议或PROFIBUS进行连接。CPU和本地S700 /O模块的通信速度非常快。2毫秒的  I/O扫描时间是可能的。每个通道都实现了短路和断线检测。

The Central Processing unit (CPU) module is equipped with a high-performance processor for fast cycle times. It has an onboard 100 Mbit/s Ethernet connection for communication between controllers, operator stations and engineers. The two serial line interfaces are connected.

One interface can be used for Modbus communication, while the other is used for diagnostics. The CPU has 10 MB of memory, of which 2 MB is the spare battery. For demanding applications, eight cycle time adjustable cycle and priority driven tasks can be configured to suck - a cycle PLC-type task that runs as fast as possible. A small front panel display displays status and diagnostic information directly on the module.

In addition, you can lock the controller by pressing a button. This means that the controller can be prevented from downloading applications and firmware for increased security. If the controller is locked or unlocked, the status will be displayed on the display. The S700 I/O module can be plugged directly into the CPU module or used as remote I/O via PROFIBUS. - A controller can be connected to a maximum of eight modules. Third party I/ OS can be connected via MODBUS ASCI/RTU, IEC 60870-5-101 remote control protocol, or PROFIBUS. The communication speed between the CPU and the local S700 /O module is very fast. An I/O scan time of 2 milliseconds is possible. Short circuit and broken line detection are realized in each channel.
