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
