Python script for accessing programmble power strip

#-----------------------------------------------------------------------------------

Import minimalmodbus

#Create an instance of an instrument (Modbus slave)

#Replace \dev\ttyACM0 with correct device string, 1 is the slave ID

pwrStrip = minimalmodbus.Instrument(‘\dev\ttyACM0’, 1)

#Set baudrate to be 9600bps

pwrStrip.serial.baudrate = 9600

#in the following method call, 0 is the coil address, 1 means True (0 is False), 5 is the function code for writing a coil

pwrStrip.write_bit(0,1,5) #activates relay 1 and turns off load controlled by relay 1.

#similarly,

pwrStrip.write_bit(1,1,5) #activates relay 2 and turns off load controlled by relay 2.

pwrStrip.write_bit(2, 1,5) #activates relay 3 and turns off load controlled by relay 3.

pwrStrip.write_bit(1,0,5) #deactivates relay 1 and turns on load controlled by relay 1.
