Precautions

When using the UNS2980c-ZV4 PLC, make sure that it is properly installed and wired according to the requirements in the product manual.

Regularly check the operating condition of the PLC to ensure that it works properly. If any abnormality or malfunction is found, please contact ABB customer service or professional maintenance personnel to handle it.

Avoid using the PLC in harsh environmental conditions, such as high temperature, humidity, dust and other environments, so as not to affect the performance and life of the PLC.

Basic Functions

Data buffer: Since the rate of I/O devices is low while the rate of CPU and memory is high, a buffer must be set up in the controller. In the output, the buffer is used to store the data coming from the host at high speed, and then the data in the buffer will be transmitted to the I/O device at the rate of the I/O device; in the input, the buffer is used to store the data coming from the I/O device, and then the data in the buffer will be transmitted to the host at high speed after a batch of data has been received.

Error control: The device controller also manages error detection of data sent from I/O devices. If an error is found in the transmission, the error detection code is usually set and reported to the CPU, which then cancels the transmitted data and transmits it again. This ensures the correctness of the data input.

Data exchange: This refers to the realisation of data exchange between the CPU and the controller, and between the controller and the device. For the former, it is through the data bus, by the CPU in parallel to write data into the controller, or from the controller in parallel to read out the data; for the latter, it is the device will be the data input to the controller, or from the controller to the device. For this purpose, data registers shall be set up in the controller.

Status Description: Identifies and reports the status of the device The controller shall note down the status of the device for the CPU to know. For example, the CPU can start the controller to read data from the device only when the device is in a transmit-ready state. For this purpose, a status register shall be set up in the controller with each bit therein reflecting a particular state of the device. When the CPU reads in the contents of this register, it will know the state of the device.

Receive and recognise commands: The CPU can send many different commands to the controller, and the device controller should be able to receive and recognise these commands. To this end, there should be a corresponding control register in the controller to store the received commands and parameters, and decode the received commands. For example, the disk controller can receive Read, Write, Format and other 15 different commands from the CPU, and some commands also have parameters; accordingly, there are several registers and command decoders in the disk controller.

Address recognition: Just as each unit in memory has an address, so does each device in the system, and the device controller must be able to recognise the address of each device it controls. In addition, in order for the CPU to be able to write to (or read from) registers, these registers should all have unique addresses.
