【功能描述】
Z7138是一款数字输出模块，它在工业自动化和控制系统中发挥着关键作用。
以下是关于Z7138的一些主要特点和功能：
数字输出功能：Z7138模块主要用于将控制系统中的数字信号转换为可以驱动外部设备的输出信号。它可以将微处理器或PLC（可编程逻辑控制器）中的指令转换为对应的数字输出，从而控制如电磁阀、电机等设备的开关状态。
缓冲功能：由于I/O设备的速率可能较低，而CPU和内存的速率通常较高，Z7138模块设置了缓冲器。这个缓冲器在输出时暂存由主机高速传来的数据，然后以I/O设备所具有的速率将缓冲器中的数据传送给设备。这确保了
数据的完整性和准确性，避免了因速率不匹配导致的数据丢失或错误。
差错控制：设备控制器还负责检测由I/O设备传送来的数据是否存在差错。如果发现传送中的错误，Z7138模块会将差错检测码置位，并向CPU报告，CPU将作废本次传送的数据，并重新进行传送。这确保了数据输入的正确性，
提高了系统的可靠性。
数据交换能力：Z7138模块实现了CPU与控制器之间、控制器与设备之间的数据交换。为了实现这一功能，模块中设置了数据寄存器，确保数据在传输过程中的准确性和稳定性。
广泛的应用领域：由于其出色的性能和稳定性，Z7138数字输出模块被广泛应用于各种工业领域，包括数控机械、冶金、石油天然气、石油化工、化工、造纸印刷、纺织印染、机械、电子制造、汽车制造等。在这些领域中，
它帮助实现设备的精确控制，提高生产效率，降低运营成本。
总的来说，Z7138数字输出模块是一款功能强大、性能稳定、应用广泛的工业控制组件。它能够满足各种工业自动化和控制系统的需求，提高生产效率，降低运营成本，为企业创造更大的价值。

【英文介绍】
The Z7138 is a digital output module that plays a key role in industrial automation and control systems.
Here are some of the key features and functions of the Z7138:
Digital output function: The Z7138 module is mainly used to convert digital signals in the control system into output signals that can drive external devices. It can convert the instructions in the
microprocessor or PLC (programmable logic controller) into the corresponding digital output, so as to control the switching state of devices such as solenoid valves and motors.
Buffering: Since I/O devices may have low rates, while CPU and memory rates are usually higher, the Z7138 module has a buffer. This buffer temporarily stores the data coming from the host at
high speed during output, and then transmits the data in the buffer to the device at the rate that the I/O device has. This ensures data integrity and accuracy and avoids data loss or errors due
to rate mismatches.
Error control: The device controller is also responsible for detecting errors in the data transmitted by the I/O device. If an error is found in the transmission, the Z7138 module will set the error
detection code and report it to the CPU. The CPU will cancel the transmitted data and retry the transmission. This ensures the correctness of data input and improves the reliability of the system.
Data exchange capability: The Z7138 module realizes the data exchange between the CPU and the controller, and between the controller and the device. In order to achieve this function, the data
register is set in the module to ensure the accuracy and stability of the data in the transmission process.
Wide range of applications: Due to its excellent performance and stability, Z7138 digital output module is widely used in various industrial fields, including CNC machinery, metallurgy, oil and gas,
petrochemical, chemical, paper printing, textile printing, machinery, electronic manufacturing, automobile manufacturing, etc. In these areas, it helps to achieve precise control of equipment, improve
production efficiency and reduce operating costs.
Overall, the Z7138 digital output module is a powerful, stable and widely used industrial control component. It can meet the needs of various industrial automation and control systems, improve
production efficiency, reduce operating costs, and create greater value for enterprises.
