Open Discussion / Illegal Data Address - 2

« on: December 20, 2022, 09:51:36 AM »

Hi
Started Advanced HMI, abandoned it and now trying again to get it going

Trying to build a very simple drag and drop project
Bought a Temperature / Humidity Sensor - Modbus RTU (XY - MD02)

I can read the values on a Generic Modbus Tester

Tried it on Advanced HMI by giving the same address and get an ILLEGAL DATA ADDRESS - 2 error
Tried 3 different panel meters with different formats in PLCAddressValue (30001, 030001, 300001...)

Can see someone did a similar project and got it going - https://youtu.be/pEtde_xk-zU

Can some one help me out, determined to get it working

Thanks

Support Questions / Still trying to find the registers used by my GE PLC, no luck

« on: September 03, 2022, 04:17:51 PM »

We have this Versamax GE PLC which is connected to 2 nos Hakko HMIs by RS485
Trying to add another free

HMI using Advanced HMI software
Do not have the modbus register details where the info is stored
It is a very basic program of Alarm inputs and displaying the alarms

I wrote this small very very very basic program to scan these addresses
No luck. Can someone suggest the mistake i an into and guide me

Thanks

\Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
DigitalPanelMeter1.PLCAddressValue = DigitalPanelMeter1.PLCAddressValue + 1
DigitalPanelMeter2.PLCAddressValue = DigitalPanelMeter2.PLCAddressValue + 1
DigitalPanelMeter3.PLCAddressValue = DigitalPanelMeter3.PLCAddressValue + 1
BasicLabel1.Text = DigitalPanelMeter1.PLCAddressValue
BasicLabel2.Text = DigitalPanelMeter2.PLCAddressValue
BasicLabel3.Text = DigitalPanelMeter3.PLCAddressValue

If DigitalPanelMeter1.Value > 0 Then
PilotLight1.Value = 1
Timer1.Stop()
Else
PilotLight1.Value = 0
End If
If DigitalPanelMeter2.Value > 0 Then
PilotLight2.Value = 1
Timer1.Stop()
Else
PilotLight2.Value = 0
End If
If DigitalPanelMeter3.Value > 0 Then
PilotLight3.Value = 1
Timer1.Stop()
Else
PilotLight3.Value = 0
End If

Support Questions / Connecting to GE CPU001 PLC using pilot light and plcaddressvalue

« on: September 01, 2022, 03:00:32 PM »

Hi
Thanks for a great program and experimenting more with GE CPU001
We have an Alarm monitoring system where we have all discrete inputs to the PLC and are monitored by an HMI (RS485)
The ladder logic on the PLC have Auxiliary relay coils M00301 to M00350
I finally got my PLC connected through my USB-RS485 adapter 9600,8,None,1, Com2 (ModbusRTUCom1)
On my Mainform have 2 pilot lights with PLCAddressValue - 00334 and 00348 (M00334 and M00338)
When I physically change the inputs the connected HMI value changes while I get Bad Checksum error?
Do I need to change plcaddressaddress 00334 / 00348 to some other address Modbus format?
Just need an pilot light indicator to turn on when there is an input without any major code
Can someone pls explain in layman terms what I am missing
Thanks
