Rotork（罗托克）第三代阀执行机构检测系统

    Rotork（罗托克）推出了Pakscan P3，它是双线数字化监测控制系统的第三代产品——这些产品主要是为阀门执行器和相关工厂设备所设计的。Pakscan P3保留了Pakscan IIE系统所有的特征。它取代并且增加了些新的科技，这些新的科技都产生于消费者所驱动的新发展。

    它的新特征可以划分成两类；一类可以提高系统的操作性能和机械性；两一类可以使安装和操作变得更为简易。前者含有以太网连通、内置的安全网络服务、时间同步设置、主机信息数据记录、领域单位命令、情况变化以及警告状态下的电子邮件通告。

    另外，主位、主机通信也已增强，有两个串行端口、两个以太网端口一个以太网外置端口。经由以太网，多达10个主机可同时与主位交流。控制器参数的重新调整可以在主位上进行，或者可以通过主机串行和以太网连接进行远程控制。

    Pakscan P3是为单频道、双频道、应急操作系统设置的，以及使用Modbus RTU和TCP protocols，这个新的系统可以完整无痕得进入现有Pakscan设置。

Rotork has launched Pakscan P3, the third generation of its two-wire digital monitoring and control system for valve actuators and associated plant equipment. Pakscan P3 inherits all the features of the Pakscan IIE system that it supersedes and adds technological advances born out of customer-driven evolution and refinement. The new features can be divided into two categories; those that increase the performance and flexibility of the system and those that make it easier to install and operate. The former include Ethernet connectivity, a built-in secure web server, time synchronisation, data-logging of host messages, field unit commands and status changes and email notification of alarm conditions.

In addition, master station host communications have been enhanced to include two serial ports, two Ethernet ports and an Ethernet configuration port. Via Ethernet, up to 10 concurrent hosts can be actively communicating with the master station. Re-programming of individual field control unit parameters can be performed at the master station, or remotely via the host serial or Ethernet link. Pakscan P3 is configurable for single channel, dual channel and hot standby operation, and using Modbus RTU and TCP protocols, the new system can be seamlessly integrated into existing Pakscan installations.
