<div class="markdown_content"><p>Hi Damian. It looks like you are trying to setup a modbus slave to talk to your Weintek.</p> <p>Is it easier to use the CODESYS V3 (Ethernet) driver on the Weintek? Page 150 of this document for the details.<br/> <a href="https://dl.weintek.com/public/PLC_Connect_Guide/eng/PLC_connection_guide.pdf" rel="nofollow">https://dl.weintek.com/public/PLC_Connect_Guide/eng/PLC_connection_guide.pdf</a></p> <p>For coils, in the current version, you need to tick "discrete bit areas" in the general tab of the modbus TCP device.</p> <p>The modbus TCP device is only for %I and %Q areas, and can be mapped to specific tags.</p></div>

<div class="markdown_content"><p>Hi,<br/> I try connected WEINTEK HMI with my PFC200 (CODESYS v3.5).<br/> Firstly, I try only read register according with documentation for example :<br/> variable in %MW0 should be in 12288 modbus register. But it doesn't work.</p> <p>So, in my project I add ModbusTCP_Slave_Device and it is works. I can read / write data form HMI. <br/> Why in my project in Mapping window I have only input and holding register? How can I read coils ?<br/> I can use M memory area? - not Q.<br/> It is possible write/read REAL variable ? </p></div>
