Modbus power meter working with eModbus (Arduino), need insight(s) for FreeModbus (ESP-IDF)

Postby brainstorm » Sat Mar 26, 2022 1:05 pm

Hello!

I've successfully setup an ESP32S2 Saola board with eModbus (https://emodbus.github.io), so I know for sure that there are no hardware issues and the values shown in the power meter's display match what I'm seeing over the Modbus-RTU twisted pair, see this thread for in-depth details on how I got the hardware up and running w/ Arduino:

https://github.com/eModbus/eModbus/discussions/166

Working with Arduino first:

  //  0023:    0.000   <---  uAh
  //  0025:    0.030   <---  -uAh
Helped me put together the CID table I'd later use on the ESP-IDF branch (https://github.com/brainstorm/yigedianq ... #L122-L155) on which I use PlatformIO with ESP-IDF version 4.4.0 (via platform = https://github.com/tasmota/platform-esp ... asmota/203 branch on platform.ini):

};
Now I'm trying to tilt up the same experiment with ESP-IDF instead, since the RainMaker integration seems to be more mature for ESP-IDF (see: viewtopic.php?f=41&t=26552). See this branch for my work in progress w/ ESP-IDF:

https://github.com/brainstorm/yigedianq ... -rainmaker

Unfortunately I'm getting non stable and completely out of range values out of the code above, see the output logs from the serial dongle:

https://hardbin.com/ipfs/QmX8d9wYPyV51k ... z5ZpH2jUrq

For instance, in TL;DR form:

I (4202) app_modbus: Characteristic #0 Amps_phase_1 (A) value = -0.000000 (0xa2343fb4) read successful.
I (7142) app_modbus: Characteristic #0 Amps_phase_1 (A) value = 9896461401915671303770759400200863744.000000 (0x7cee3fa7) read successful.
I (10082) app_modbus: Characteristic #0 Amps_phase_1 (A) value = 41405882368.000000 (0x511a3fba) read successful.

So I suspect this is a case of not properly initialized variables or registers? Perhaps timing or race condition issues? Incorrect type casting?

Other than reviewing other user's ESP-IDF Modbus repo (solved) issues and this Forum's posts, I've noticed that Alex Lisitsyn (https://github.com/alisitsyn) has been extremely helpful troubleshooting other user's issues. I hope this post gets noticed by him or somebody else so that I get to finish up this project properly :)

Re: Modbus power meter working with eModbus (Arduino), need insight(s) for FreeModbus (ESP-IDF)

I've now removed the alarm code from the modbus master example (in https://github.com/brainstorm/yigedianq ... 09093d5e65) and it seems to iterate through the rest of the CID table, but the numbers do not look right at all still.

The FreeModbus raw buffer responses look a bit shorter than those from eModbus (see https://github.com/eModbus/eModbus/disc ... nt-2386579), which tells me that I might be either requesting too few bytes or reading the wrong ones when they are available on the buffer after a ModBus response. The dongle flashes on the RX/TX LEDs, so the readout is unlikely to be an uninitialized region of memory?

Also, the message "MB_MASTER_SERIAL: Timeout occured, processed: 10 bytes" concerns me too, I don't know if timeouts are supposed to occur, I'll check the esp-idf FreeModbus code to figure more things out of this.

Re: Modbus power meter working with eModbus (Arduino), need insight(s) for FreeModbus (ESP-IDF)

Postby brainstorm » Sat Mar 26, 2022 11:57 pm

Trimming the Modbus CID table code further (see https://github.com/brainstorm/yigedianq ... f2eaf30429).

This change is meant to focus on just one attribute (instantaneous Watts) getting requested on the bus. Unfortunately still fails yielding "0.000"(Watts) when the display of the device shows ~"1.8"(Watts)... then, shortly after a few iterations, it goes to 271829599374318099234816.000000 (Watts) :-!!

Re: Modbus power meter working with eModbus (Arduino), need insight(s) for FreeModbus (ESP-IDF)

Postby brainstorm » Sun Mar 27, 2022 6:55 pm

Nevermind, I managed to solve it by adding some offsets to the modbus attribute IDs on the CID table (different from those that worked on eModbus Arduino): https://github.com/brainstorm/yigedianq ... fR125-R155

I.e for some reason, in eModbus/Arduino:

Code: Select all

  //  0011:    0.193   <--- Amps panel 1
  //  0013:    0.258   <--- Amps panel 2
  //  0015:    0.210   <--- Amps panel 3
Whereas in esp-idf/FreeModbus:

Code: Select all

    { CID_HOLD_DATA_0, STR("Amps_phase_1"), STR("A"), MB_DEVICE_ADDR1, MB_PARAM_HOLDING, 0x12, 2,
            HOLD_OFFSET(holding_data0), PARAM_TYPE_FLOAT, PARAM_SIZE_FLOAT, OPTS( 0, 5000, .001 ), PAR_PERMS_READ },
    { CID_HOLD_DATA_1, STR("Amps_phase_2"), STR("A"), MB_DEVICE_ADDR1, MB_PARAM_HOLDING, 0x14, 2,
            HOLD_OFFSET(holding_data1), PARAM_TYPE_FLOAT, PARAM_SIZE_FLOAT, OPTS( 0, 5000, .001 ), PAR_PERMS_READ },
    { CID_HOLD_DATA_2, STR("Amps_phase_3"), STR("A"), MB_DEVICE_ADDR1, MB_PARAM_HOLDING, 0x10, 2,

Hi @brainstorm,
Also, the message "MB_MASTER_SERIAL: Timeout occurred, processed: 10 bytes" concerns me too, I don't know if timeouts are supposed to occur, I'll check the esp-idf FreeModbus code to figure more things out of this.
Timeout means the UART T3.5 timeout here.
The message in the log as below displays just ADU (Application Data Unit) of the Modbus Frame, so the length is 9 bytes is correct.
`D (9932) POLL receive buffer: 03 04 3f ba 51 1a`
The FreeModbus raw buffer responses look a bit shorter than those from eModbus
I read your post and code you shared. What I need is actually your power meter Modbus mapping table. It seems that your device has a different float format for data stored in the registers. It could be not just endianess/swap but it seems that it uses double type (8 bytes) instead of 4 bytes float IEEE754 format https://www.h-schmidt.net/FloatConverter/IEEE754.html
used in Modbus stack code. Your workaround is just a temporary solution in this case. However, the code of the stack can be fixed to convert data to the format of your device. I need the mapping table from you to help.

Thanks.

TL;DR, the interesting parts start on page 10 of that manual.

Re: Modbus power meter working with eModbus (Arduino), need insight(s) for FreeModbus (ESP-IDF)

Postby brainstorm » Fri Apr 08, 2022 4:26 am

I've found out that the manual I just scanned and posted here is for the meter with model number YG899E-9SY, which does not correspond with my yigedianqi-modbus CID table because tha CID table I've written in my code is for model YG194E-9SY.

Both model's parameters seem to be laid out (correctly?) on those two YAML definitions I've found in another project:

https://github.com/GuillermoElectrico/e ... 9E-9SY.yml
https://github.com/GuillermoElectrico/e ... 4E-9SY.yml

Hope that helps solving the float encoding issues you mentioned earlier in FreeModBus while you are rearranging the code in esp-modbus on https://github.com/espressif/esp-modbus.

@brainstorm ,

Thank you for the information. Unfortunately, I can not read Chinese but most of the information included there is clear. As I mentioned before and as the manual confirms the float format representation in Modbus is not the same. The YG899E-9SY float format is IEEE754 4 bytes but it is not swapped. The ESP-Modbus uses IEEE754 Little-endian byte swap format which is common for most of devices.
For Example ESP-Modbus the read of 218.799 float value from holding registers:

Code: Select all

Request: 01 03 00 06 00 02 24 0A
Response: 01 03 04 CC 9D 43 5A E5 86
The YG899E-9SY will respond as:

Code: Select all

Response: 01 03 04 43 5A CC 9D 5B 0D
This is not an issue in the Modbus stack it is a customized version of Modbus protocol used in your device. The Modbus spec does not prevent this. There is a plan to add the support of a customized format for 32bit values in the stack but it is not supported for now.

In order to add support for this format you need to implement byte swapping of the float value in the code:
https://github.com/espressif/esp-idf/bl ... ter.c#L388

The better way is to fix the code of the library as below:

Code: Select all

static esp_err_t mbc_serial_master_get_parameter(uint16_t cid, char* name,
                                                    uint8_t* value_ptr, uint8_t *type)
{
    MB_MASTER_CHECK((name != NULL),
                        ESP_ERR_INVALID_ARG, "mb incorrect descriptor.");
    MB_MASTER_CHECK((type != NULL),
                        ESP_ERR_INVALID_ARG, "type pointer is incorrect.");
    esp_err_t error = ESP_ERR_INVALID_RESPONSE;
    mb_param_request_t request ;
    mb_parameter_descriptor_t reg_info = { 0 };

    error = mbc_serial_master_set_request(name, MB_PARAM_READ, &request, &reg_info);
    if ((error == ESP_OK) && (cid == reg_info.cid)) {
        // Send request to read characteristic data
        error = mbc_serial_master_send_request(&request, value_ptr);
        if (error == ESP_OK) {
            ESP_LOGD(MB_MASTER_TAG, "%s: Good response for get cid(%u) = %s",
                                    __FUNCTION__, (int)reg_info.cid, (char*)esp_err_to_name(error));
        } else {
            ESP_LOGD(MB_MASTER_TAG, "%s: Bad response to get cid(%u) = %s",
                                            __FUNCTION__, reg_info.cid, (char*)esp_err_to_name(error));
        }
        // Set the type of parameter found in the table
        *type = reg_info.param_type;
        if (((reg_info.param_type == PARAM_TYPE_FLOAT) || (reg_info.param_type == PARAM_TYPE_U32)) 
                && (reg_info.param_size == 4)) {
            	// Fix endianess for FLOAT and U32 parameter here <<<<<<<<<<<<<<<<<<<
            	*(uint32_t*)value_ptr = __beswap_32(*(uint32_t*)value_ptr);
        }
    } else {
        ESP_LOGE(MB_MASTER_TAG, "%s: The cid(%u) not found in the data dictionary.",
                                                    __FUNCTION__, reg_info.cid);
        error = ESP_ERR_INVALID_ARG;
    }
    return error;
}
I was discussing about this here: viewtopic.php?f=2&t=23040&hilit=modbus+floating .
I will implement the change in the esp-modbus component soon. Please verify this with your device.
