Hi there, I am trying to run your code on a Pi Zero W with the latest version of Raspian Stretch

However, when I run this code

#################################

!/usr/bin/env python

from pymodbus.client.sync import ModbusSerialClient as ModbusClient client = ModbusClient(method = 'rtu', port = '/dev/ttyAMA0', baudrate = 115200) client.connect() while True: result = client.read_input_registers(0x03, 1, unit=1) print result client.close()

###############################

it returns this error

###############################

#############################

i'd be most grateful for any advise on how to solve this

kasbert commented 5 years ago

It might be a problem with the Raspbian distibution. Here is a similar case: https://www.raspberrypi.org/forums/viewtopic.php?t=218469

seesix commented 5 years ago

I just tried with a fresh install of Jessie and same error. My guess is, its the cable, I'm using the one supplied by Epever, have order a new one.

seesix commented 5 years ago

I have just tried again with a new FTDI cable and it returns this error.

Any ideas on how to fix this would be gratefully received.

Thanks

Edit info.py and set correct arguments:

serialclient = ModbusClient(method='rtu', port='/dev/ttyXRUSB0', baudrate=115200, stopbits = 1, bytesize = 8, timeout=1)

Do you see the wanted the /dev/tty* device ?

seesix commented 5 years ago

thank you so much for the help.

in the end my device was ttyUSB1

hey kasbert

i'm still stuck on this, when i run info.py i get this

============================== note that it reads only one input from the register

Real time clock 1 = 11270

if i run the script again i'll get a different single value returned ie

Charging equipment rated output current = 60.0A

here is my info.py

=========================================

!/usr/bin/env python

from pyepsolartracer.client import EPsolarTracerClient from pyepsolartracer.registers import registers,coils

from test.testdata import ModbusMockClient as ModbusClient

from pymodbus.client.sync import ModbusSerialClient as ModbusClient

configure the client logging

import logging logging.basicConfig() log = logging.getLogger() log.setLevel(logging.INFO)

serialclient = ModbusClient(method='rtu', port='/dev/ttyUSB0', baudrate=115200, timeout=5, stopbits =1, bytesize =8, handshaking ='N', parity ='N', debug = True)

client = EPsolarTracerClient(serialclient = serialclient) client.connect()

response = client.read_device_info()

print "Manufacturer:", repr(response.information[0])

print "Model:", repr(response.information[1])

print "Version:", repr(response.information[2])

response = client.read_holding_registers(0, 1, unit=1)

response = client.read_input("Charging equipment rated input voltage")

print str(response)

for reg in registers:

print

#print reg
value = client.read_input(reg.name)
print value
#if value.value is not None:
#    print client.write_output(reg.name,value.value)

for reg in coils:

print

#print reg
value = client.read_input(reg.name)
print value
#print client.write_output(reg.name,value.value)

client.close()

===============================================

Any ideas what I'm doing wrong? Thanks again for the help
