EHC 105 00 模块是 Modicon Quantum 控制器的一种高速计数器模块。EHC 105 00 包含 5 个独立的计数器。每个计数器可在 5 或 24 VDC 脉冲输入信号条件下工作。计数器可在下列操作模式下工作：
·事件计数器（32 位，具有四种不同的操作模式）
·差分计数器（32 位，具有两种不同的操作模式）
·重复计数器（16 位）
·速度计数器（32 位，具有两种不同的操作模式）
可以监控的最大计数频率为 100 kHz ，具体取决于电缆长度、发射器类型和电压。有八个隔离的离散量输入和八个隔离的离散量输出（24 VDC 电平）可用。这些I/O 点可分配给各个计数器的不同信号。
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 network cards can be interconnected with each other to form a special
Redundant communication link (diginetr) to ensure information synchronization between master and slave PS. — However, the master PS fails, and the slave PS can quickly and undisturbed connect the replacement worker
Make. All inputs and outputs also support redundant operation.
The data communication between the field process controller PS. operating station 0s and the engineer station es is completed by the system network (diginets), which is inserted
The – Ethernet network card on the PS basic unit provides the interface between PS and diginets. ES. Hardware config
uration and PS
The user program is downloaded to the PS CPU through diginets and the first network card. After the field bus interface card is newly installed or replaced, the required group
The status information will be automatically reloaded. The configuration results and real-time process data are stored in RAM, and ram is installed on the Ethernet network card or battery card
The backup battery can maintain the configuration content and data in case of power failure.
