  1. Hello, Which sensors do you want to use, there is really well made example code in the doc for python ? No idea how you can get the UID without brick viewer
  2. Hello everybody, I'm working on an industrial special machine and i want to control some part of it with bricklet. My machine can do round trip on a rail with a motor and its coder. the PLC keep the control of all the power, I just send him order with a RS232 bricklet. For a first test i want to go to 30 000 counts, wait 2 seconds and then go back to my initial position ( 0 ) and repeat forever. Here is the issue : my machine drift in a single direction about some centimeters each time. When I control it directly by the PLC i haven't that and I don't understand why it does it with the counter bricklet. the coder is a sew eurodriver EH1C, I connect CH0- and CH2- to GND and CH0+ and CH2+ to A & B Here is my code : from tinkerforge.ip_connection import IPConnection from tinkerforge.bricklet_rs232_v2 import BrickletRS232V2 from tinkerforge.brick_master import BrickMaster from tinkerforge.bricklet_industrial_counter import BrickletIndustrialCounter import time HOST = "localhost" PORT = 4223 UID = "6eSrKP" # Change XXYYZZ to the UID of your Master Brick UID_RS = "W9P" UID_COUNTER = "QV8" ipcon = IPConnection() # Create IP connection rs232 = BrickletRS232V2(UID_RS, ipcon) # Create device object counter = BrickletIndustrialCounter(UID_COUNTER, ipcon) # Create device object ipcon.connect(HOST,PORT) counter.set_counter_configuration(counter.CHANNEL_0, counter.COUNT_EDGE_RISING, counter.COUNT_DIRECTION_EXTERNAL_DOWN, counter.DUTY_CYCLE_PRESCALER_1, counter.FREQUENCY_INTEGRATION_TIME_1024_MS) counter.set_all_counter_active([True, False, False, False]) counter.set_counter(0, 0) i = 0 speed = 40 while True : message = [chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(speed),chr(2)] # the first 7 control IR power the 8th the speed and the 9th the direction rs232.write(message) time.sleep(2) message = [chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(speed),chr(1)] rs232.write(message) while counter.get_counter(0)<75000: print(counter.get_counter(0)) message = [chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(speed),chr(2)] rs232.write(message) time.sleep(2) message = [chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(i),chr(speed),chr(0)] rs232.write(message) while counter.get_counter(0)>0: print(counter.get_counter(0))
