Description
1B30035H01 Emerson Ovation HART Analog Output Module
thereby controlling external devices or circuits.
This refers to the implementation of data exchange between CPUs and controllers, as well as between controllers and devices. For the former, data is written to the controller in parallel by the CPU through the data bus, or read from the controller in parallel; For the latter, the device inputs data into the controller or transmits data from the controller to the device. For this purpose, data registers must be set up in the controller.
4. Status description
The status controller for identifying and reporting equipment should record the status of the equipment for the CPU to understand. For example, the CPU can only start the controller to read data from the device when it is in the ready to send state. For this purpose, a status register should be set up in the controller, where each bit reflects a certain state of the device. After the CPU reads the contents of the register, it can understand the status of the device.
5. Receive and identify commands
The CPU can send various commands to the controller, and the device controller should be able to receive and recognize these commands. For this purpose, the controller should have corresponding control registers to store received commands and parameters, and decode the received commands. For example, a disk controller can receive 15 different commands such as Read, Write, Format, etc. sent by the CPU, and some commands also have parameters; Correspondingly, there are multiple registers and command decoders in the disk controller.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 1B30035H01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
