ESP8266 MEMORY ADDRESS

[methaqali]

Thank you for this library. I have ESP8266 programmed to operate at MODBUS TCP / IP and PLC (LSIS) connected to router by Ethernet MODBUS. I made connection between them successfully (using P2P service found in PLC) through router, but the connection produce error. P2P service used to make connection between LSIS devices and other devices. This service requires inter the read and write memory address for ESP8266 with condition that the address must has 5 digit. Knowing that I use simple diode connection on GPIO pin-14. The problem is when I search for ESP8266 memory map addresses, I find it (0x60000360) 8 digit and this return error from PLC side. I dont know how to make reduction for ESP8266 register address . Please help me.

Hello, I'm not exactly sure that understanding you needs right, but it seems to me that you need to create at ESP side Modbus Coil with address 12345 (whatever 0..65535) and add callbacks to get/set pin value on external modbus requests. (Code is very alike Callback sample just need to add onGetCoil). From other hand your PLC probably assume using Hreg not Coil. So you can try to implement code described above for Hreg (just replace Coil with Hreg).

Thank you emelianov for replay, I tried above code, it return illegal data error when use modbus poll and CAS Mod scaner softwares (the blue led in ESP8266 continues glow).

[emelianov]

For CAS Modbus scanner you need to use +1 offset. I mean for read/write Coil 100 (numbering at ESP side) you need use 101 offset at CAS side. Also make sure to change length to 1 from default.

[methaqali]

I confused what the mean of length and CAS modbus already add 1 offset to address it refusing change offset to (0)

[emelianov]

For code from Callback.ino example (coil address is 100) you need following CAS settings:

[methaqali]

I tried to connect use callback.ino but connection failed.Are you sure this library working well?

[methaqali]

this is the error seen in the IDE serial

[emelianov]

I've got simular exception with Arduino/Core 2.5.Beta2. Try to use 2.4.2 -- Callback.ino runs stable that case. I will try to investigate the problem.

[methaqali]

I was try this code its working perfect with out need library, my problem only in know to inter the correct plc address in modbus poll software to operate diode(say in GPIO 14)

ok thanks , what about pre-mapping between the MODBUS data model and ESP8266 device application. Are you have document for this issue.

[emelianov]

Library responsible only for Modbus layer. It may function absolutely separate from application logic. Application should use call backs or checking/setting registers from main loop.

[methaqali]

Thats right I have succeed in send address from cas modbus to ESP make diode on - off but same address send by PLC with out make the same diode to operate, I dont know why axcactly!!

[emelianov]

Try to catch request data that PLC sends to slave. You can install for example PeakHMI Modbus Slave Simulator (https://www.hmisys.com) and look Communication Monitor output.

error: Failed to open COM5 Arduino IDE doesn't see ESP board at COM5 or port is busy by another application. May be you need just retry FW upload attempt. Check Tools\Port settings. Probably board port has been changed.

[methaqali]

I mean this type of error "Invalid library found in C:\Users\lenovo\Documents\Arduino\libraries\OneWire-master: no headers files (.h)" its not effect the uploading of program but annoy me.

[methaqali]

emelianov, Could you help me: I have the following code to make MODBUS tcp/ip(its work good) the other issue in the code is ultrasonic sensor (trig on D1& echo on D2 and output distance on serial port)I want to write distance on one of memory register say (3). I use the command "digitalWrite(distance, MBHoldingRegister[3] )" its fail then I use analogWrite also fail what's the solution?

emelianov, Could you help me: I have the following code to make MODBUS tcp/ip(its work good) the other issue in the code is ultrasonic sensor (trig on D1& echo on D2 and output distance on serial port)I want to write distance on one of memory register say (3). I use the command "digitalWrite(distance, MBHoldingRegister[3] )" its fail then I use analogWrite also fail what's the solution?

Just replace distance = getDistance(); with MBHoldingRegister[< desired HReg # to store distance (< 20) >] = getDistance();

I'm so grateful for you my friend.

Hi emelianov, I need to use static IP for ESP8266 and add the following commands to upper code after that ESP connected with router but plc and modbus software both not connected with ESP and give error "time out" IPAddress staticIP224_60(192,168,1,60); IPAddress gateway224_60(192,168,1,1); IPAddress subnet224_60(255,255,255,0);

void setup() { Serial.begin(9600); WiFi.config(staticIP224_60, gateway224_60, subnet224_60) what is the wrong?
