Hello, the error code for the client tcp module is : add1: 16#0A0F0111 and add2: 16#0C23020E. In the documentation, this means that the connection has been closed. The problem is that when I use the module to retrieve the module constructor information with the client tcp module, I get it. The variables are of type "float 32", my question is: should I use an array of type "word" with its "pointer to word"? I confess that I do not understand. I put additional screenshots. Thank you in advance for your answer       ... View more

Hello, despite the information, it does not work. Either with the module "ModbusTCPReadInputRegisters or ModbusTCPReadHoldingRegisters". The error is "resource_error" and the code "additionnal 1 = 16#0A0F1850" and the code "additionnal 2 = 16#0c230003". Unfortunately, these error codes are not found in the documentation. If you have any information, thank you in advance for your reply, Kévin ... View more

I have succeeded in communicating with my modbus module (the IL_ModbusTCPclient module and the IL_modbusTCPRead device Identification module are working), but I can't read the information in the registers (float 32) of the Schneider module. I don't know what the differences are between the ModbusTCPReadCoils, ModbusTCPReadHoldingRegister and ModbusTCPReadinputRegister blocks. In my case, I created a real array to store the data with a word pointer to it. But it gives me as error : Resource_error for the ModbusTCPReadinputRegister block which means an error "Input 'ModBusLink' is invalid". Communication_error for the IL_ModbusTCPclient block which means "the socket is not connected or Remote station closed Connection". I admit that if you have an idea, I would be delighted.
