3、 The functions of PLC and drivers in control systems
Functions of PLC
PLC mainly undertakes the following functions in the control system:
(1) Receive external input signals, such as signals from buttons, sensors, and other devices.
(2) Execute preset program: Perform logical operations, sequence control, and other operations according to the preset program.
(3) Output control signal: Send control signals to actuators such as drivers based on the calculation results.
(4) Monitoring device status: Real time monitoring of device operation status by receiving feedback signals from the device.
(5) Fault handling: When the equipment malfunctions, issue an alarm signal and take corresponding measures.
Function of the driver
The driver mainly undertakes the following functions in the control system:
(1) Receive control signals: Receive control signals from controllers such as PLCs.
(2) Amplify power signal: Amplify the control signal into a power signal sufficient to drive the device to move.
(3) Drive equipment operation: Convert power signals into actual current or voltage to drive the equipment to move.
(4) Receive feedback signals: Receive feedback signals from devices and transmit them back to controllers such as PLCs to form closed-loop control.
4、 Collaboration between PLC and Drivers
In industrial automation control systems, the collaboration between PLC and drivers is mainly reflected in the following aspects:
Signal transmission and conversion
PLC sends control signals to the driver through output ports, which are usually digital or analog signals. After receiving these signals,
the driver converts them into electrical signals to drive the movement of the device. At the same time, the driver can also receive feedback
signals from the device, convert them into digital or analog signals, and then transmit them back to the PLC.
