气动

气动命令仅适用于 CTE 气动部件。

初始化气动类

使用以下构造函数创建气动系统：

Pneumatic(port)

此构造函数使用一个参数：

范围	描述
port	与气动电磁阀连接的有效 智能端口。

# Construct a Pneumatic System "pneumatic_1" with the
# Pneumatic class.
pneumatic_1 = Pneumatic(Ports.Port1)

This pneumatic_1 object will be used in all subsequent examples throughout this API documentation when referring to Pneumatic class methods.

类方法

extend()

The extend(value) method extends a cylinder.

参数	描述
价值	有效的 CylinderType。

**返回：**无。

# Extend the first cylinder.
pnuematic_1.extend(CYLINDER1)

# Wait 2 seconds.
wait(2, SECONDS)

# Retract the first cylinder.
pnuematic_1.retract(CYLINDER1)

retract()

The retract(value) method retracts a cylinder.

参数	描述
价值	有效的 CylinderType。

**返回：**无。

# Extend the first cylinder.
pnuematic_1.extend(CYLINDER1)

# Wait 2 seconds.
wait(2, SECONDS)

# Retract the first cylinder.
pnuematic_1.retract(CYLINDER1)

pump_on()

The pump_on() method turns the pneumatic air pump on.

**返回：**无。

# Turn air pump on.
pnuematic_1.pump_on()

pump_off()

The pump_off() method turns the pneumatic air pump off.

**返回：**无。

# Turn air pump off.
pnuematic_1.pump_off()

pump()

The pump(state) method turns the pneumatic air pump on or off.

参数	描述
状态	The compressor state. True to turn it on. False to turn it off.

**返回：**无。

# Turn air pump on.
pnuematic_1.pump(True)

# Turn air pump off.
pnuematic_1.pump(False)

status()

The status() method returns the raw status for the pneumatic device.

**返回：**气动装置的原始状态（整数）。

installed()

The installed() method checks for device connection.

Returns: True if the device is connected. False if it is not.

timestamp()

The timestamp() method returns the timestamp of the last received status packet from the Pneumatic System.

**返回：**最后接收的状态包的时间戳（以毫秒为单位）。
