trying to read registers with radzio

[JimmyTang999]

using powershell, my code is this

Add-Type -Path "C:\myDlls\Modbus\EasyModbus.dll"
$modbusServer = [EasyModbus.ModbusServer]::new()
$modbusServer.Listen()

so i am wondering why the registers are not showing 0's?

now i did notice my client code did change the register values so i am not sure why radzio isn't seeing the stuff

Add-Type -Path "C:\myDlls\Modbus\EasyModbus.dll"
[EasyModbus.ModbusClient]$modbusClient = New-Object EasyModbus.ModbusClient

$modbusClient.IPAddress = "127.0.0.1"
$modbusClient.Port = 502

$modbusClient.Connect()

# Read holding registers
$registers = $modbusClient.ReadHoldingRegisters(0, 10)  # Read 10 holding registers starting from address 0
Write-Output "Before Changing Holding Register"
$registers

# write to a single holding register
$modbusClient.WriteMultipleRegisters(0,6)

# read the new vals
$registers = $modbusClient.ReadHoldingRegisters(0, 10)  # Read 10 holding registers starting from address 0
Write-Output "After Changing Holding Register"
$registers
$modbusClient.Disconnect()

it was a firewall issue- so AVG was controlling my windows firewall. as soon as i disabled AVGs control and restarted radzio, windows firewall asked me to allow traffic for the application. AVG was blocking all traffic without notifying.
