<div class="markdown_content"><p>My mistake, got it working. Here is screendump of working setup. Problem was i used "FC23 Read/Write Multiple Registers" and i dont think the 6050 supports this. From 6050 manual, it says:</p> <p>Code (Hex)<br/> Name Usage<br/> 01 Read Coil Status Read Discrete Output Bit<br/> 02 Read Input Status Read Discrete Input Bit<br/> 03 Read Holding Registers Read 16-bit register. Used to read integer or floating point process data.<br/> 04 Read Input Registers<br/> 05 Force Single Coil Write data to force coil ON/OFF<br/> 06 Preset Single Register Write data in 16-bit integer format<br/> 08 Loopback Diagnosis Diagnostic testing of the communication port<br/> 0F Force Multiple Coils Write multiple data to force coil ON/OFF<br/> 10 Preset Multiple Registers Write multiple data in 16-bit integer format</p> <p>so i tried Function code 03 for read inputs and Function code 15 (16#000F) for write outputs. Once did this, all good.</p> <p><img alt="IMG: Adam6050_Setup.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=942"/></p></div>

<div class="markdown_content"><p>Hi Everyone, having codesys run on he pi is brillant.</p> <p>Ok, i have the Adam 6050 Modbus TCP slave (12 in, 6 out). I've configured codesys with a modbus tcp master and modbus tcp slave and entered ip address of the slave. However codesys tells me the ModbusTcpSlave is not running. The device appears ok as i can connect to it via service tool. Any tips?<br/> Thanks</p></div>

<div class="markdown_content"><p>Hi,</p> <p>Many thanks for the support.<br/> A member of your technical support team managed to remote in to my system and resolve this issue.</p> <p>My eDAM IO unit is now up and running as a MODBUS TCP Slave (and only ~9% CPU on the RPi)</p> <p>Cheers Guys!</p></div>

<div class="markdown_content"><p>Hi,</p> <p>there's an error in the device description of "CODESYS Control for Raspberry Pi".<br/> This is only a problem if you use CODESYS V3.5.4.10.<br/> I attached a corrected version of the device description. Just install this device (Tools -&gt; Device Repository... -&gt; Install...) and then update your device in the device tree or restart CODESYS.</p> <p>Best regards<br/> 3S Support</p> <p><a class="" href="https://forum.codesys.com//download/file.php?id=516" rel="nofollow">CODESYS Control for Raspberry Pi.devdesc.zip <span><span>[9.05 KiB]</span></span></a></p></div>

<div class="markdown_content"><p>Hi,</p> <p>this should work, how do you get the CmpIecTask library error,<br/> this should not happen?<br/> Try to create an empty new Project with Raspberry Pi as plc.<br/> Then add Ethernet - then Modbus-Master then Modbus-Slave (under the Modbus Master).<br/> Compile - the this should lead to an error free compile result.<br/> If not let me know.</p> <p>BR<br/> E.Schwellinger</p></div>
