Dear sir ,

I leave in Belgium .

I use a Logo 8.4 , with analog output to send the returned power of my solar panels via a solid state relais to an electric heating ( with home made electronics ) ,In the coming months the company Fluvius change my analog meter to a digital meter meter with P1 port .

Now I am traying to make a connection between the P1 port an the Logo via a P1 modbus pro dongle of the Dutch company Smartstuff . They say the registers are in UINT 32 (4321 ) values .

I found the logo file " UINT32_SINT16_0BA8.Standard.lsc " on your forum page , it works very well to import the voltage values L1 , L2 , L3 in my Logo , but the most important value for me is the returned power in Watt . That comes in kW and it gives always a zero in the logo .

Is it possible to modify the UINT32_SINT16_0BA8.Standard.lsc or to have an other LSC routine , so that I can have the value of the retuned power in Watt to give it to the analog output of the Logo

Link to the registers of the P1 dongle : https://docs.smart-stuff.nl/p1-modbus-dongle/quick-start/registers

Attached in zip format 3 files : example "Fluvius telegram " , " UINT32_Sint16.lsc " , the problem

Many thanks

Gerard

First of all, what is the part number of your LOGO?

Please confirm if you are using ModBus TCP and not RTU because LOGO has native ModBus TCP protocol.

Find attached the map for ModBus TCP.

My Logo : 6ED1052-1CC08-OBA2 with analog output module

and modbus TCP with USR-TCP232-410s

This Data table is working properly?

The ID is 43 really?

I would like to know what is HR for the data you wants to read.....

The link you have sent is about RTU and not TCP.

the settings for the test are OK : unit ID 43 and startadres for L1 ( 19 ( 18 + 1 for PLC )

You can see that on the website of smartstuff  https://docs.smart-stuff.nl/p1-modbus-dongle/quick-start/registers

The result is 100 % ok in the test file that is attached .

the problem is there when I try with the registers  "delivred power ) adres 14 and returned power , adres 15 ( see word file in my first mail ) and the reason is that it is given in kWatt and I need it in Watt . So when it is less than 1 kW , the result is 0

with a logo file that I found in one of your replays in an other discussion  , I have the result that you shows , I was very happy with the result , I was only missing the millivolts

My real problem is " how can I read all the 32 bit unsigned date that comes from the smartstuff P1 module " ,but I cannot read the returned power ,that value is in kWatt, but when the value is less than 1 kW ( 999 W or less ) , than the Logo soft gives me zero .

Maybe , the best is to forget my " bad work " the if it is possible help me with an other routine that works on all the 32 bit uint registers

Can you help me with an other Logo routine , so that I all the registers of the P1 dongle , that are in uint32 (4321) values as discribed on his website .   https://docs.smart-stuff.nl/p1-modbus-dongle/quick-start/registers

Thancks , and I hope that there is someone that can help me

if the value of the power is less than 32,768 W , that is perfect for me .

and if it is possible use the same Logo routine for voltages les than 260 Volt than it is even better , 

sir ,

you're right,I am 77 jears old and I am not familiar with data formats and Plc's .

The only thing I can make a small aplication with a plc .

But is it possible to make a routine for the power less than 32768 Watt ( 32,768 kWatt ) ?

If that is possible , that is the most important for me .

thanck You

If it is possible , the register addresses 16 power_returned , and the register 14 power_delivered

humbertje

If it is possible , the register addresses 16 power_returned , and the register 14 power_delivered

Yes, it's possible if the values are less then 32,768.

Example:

Transfer the HR15 to VW100. Then read the VW100 with a simple analog network input.
Transfer the HR17 to VW102. Then read the VW102 with a simple analog network input.

I have transferred HR 15 to VW100 , but when I read it , the value was 0 , then I read the VW102 ( the low word of the 32 bit register ) and the value is OK .

And HR 17 to VW104 and than reading VW106 with a NAI

the value will always be lower than 32768 , 
because the max power of my solar panels is 6000 watts,
that is perfect

Many thancks for the good help .

II'm happy for you that it's working now ...
