SIWAREX MS（微量秤）是一种多用途的、灵活的称量模块；无论何处打算把秤用在S7-200自动化系统中、或者有必要进行力的测量时，都可以使用这种秤。
SIWAREX MS模块能发挥现代自动化系统的所有优势；其中包括综合通信、诊断系统和可以利用的配置工具。用户可获得的好处：
SIWAREX MS具有很多至关重要的优势：
ο 归功于在SIMATIC S7-200中使用的标准化连接技术和综合通信；
ο 利用STEP 7 Micro/Win版本4.0 SP2及更高版本的标准化配置；
ο 分辩率高达16位的重量测量或力的测量；
ο 0.05 %的高准确性；
ο 可以在20 ms或33 ms之间选择的快速测量时间；
ο 极限值的监视；
ο 能灵活地适应SIMATIC控制方面的不同要求；
ο 使用SIWATOOL MS程序，通过RS 232接口，就能容易地实现秤的调节；
ο 不需要调节重量的理论调节；
ο 模块更换方便，无需重新调节秤；
ο 适用于1类防爆区域的本质安全称重传感器电源（SIWAREX IS选项）；
ο 诊断功能。

The PS supports the following types of fieldbus standards:
Profibus DP，up to 12 MBd
Modbus RTU，1200 to 38. 4KBd
Industrial” CAN I/0 Bus
o
Open CAN -Bus，up to 1 MBd
o
Foundation Fieldbus H1
up to 31. 25KBd
Foundation Fieldbus H2 (fast Ethernet)
HART
The system allows different types of field buses to be mixed and run simultaneously in the same field controller PS.
Industrial “field control explosion (AC800F) consists of the following components:
Basic unit pm802f
Power supply sa801f/sd802f
o
Ethernet network card ei801f/ei802f/ei803f
o
Fieldbus interface card fi810f/fi820f/fi830f
Various accessories
The main components of the field controller PS are described below.
Basic unit pm802f
The basic unit pm802f is composed of a metal rack and a CPU motherboard. It periodically scans the data from the
The signals of the field bus sensors are processed according to the control application program configured by the user, and then the calculation results are passed
The fieldbus interface card returns the corresponding fieldbus actuator.
Two field controllers can realize controller 1:1 redundancy, and undisturbed switching between master and slave PS. Two on each PS
Ethernet network card, the second network card is used to connect the system network diginets), and the second
