IO 扩展模块是用于安装在 DIN 导轨上的多通道输入/输出模块。 IO 扩展模块的输入和输出经过专门的设计,它们适合 Siemens 气相色谱仪 MAXUM 和 MicroSAM 的运行概念。
IO 扩展模块具有以下接口:
• 四个数字输入 用于记录开关状态等
• 四个数字输出 (继电器输出)用于控制阀门等
• 两个模拟输入 用于记录电流电压
• 四个模拟输出 用于输出电流电压
必要时,可以对一台色谱仪使用多个 IO 扩展模块。 这样,就可以为很多的色谱分析应用提供大量接口。
IO 扩展模块可以直接靠近气相色谱仪使用,甚至可在危险区域中使用。 这样就可简化系统的设计和布线。
At the operation management level, not only the traditional control system monitoring operation function is realized
function (operation and display, printing, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems.
can. The process control stage realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control.
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as I/0 or field instruments) adopts the international standard field controller.
Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in the world.
Line international standard, divided into FMS, DP and PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application.
The popular PC and MS_ Windows 2000 have been widely used in various fields all over the world, becoming the de facto standard computer platform.
tower. The operating station 0S, the engineering station ES and the data gateway GS of the Industrial” system use this platform to ensure the system’s
Versatility, openness and ease of use, and bring great convenience to future technical upgrades and maintenance.
System engineering is very convenient. The configuration language is based on the IE061131 3 industry standard, providing function block diagram (FBD), ladder diagram
(LD), instruction list (IL), sequential function chart (SFC), structured text (ST) and other graphical configuration methods. The system contains about 220 functions
