<div class="markdown_content"><p>Hi,</p> <p>I working on updating a set of unit tests written under CODESYS V3.5 SP9 Patch 5 so that it runs under CODESYS V3.5 SP13 Patch 2. The tests run fine under the former version.<br/> However, under the latter I have run into "Exception: Value cannot be retrieved: Too many expressions" which, as far as I understand, signifies that the number of values that is to be retrieved is too large for the CODESYS buffer to handle. I have tried running a test with significantly smaller number of inputs and outputs and it works fine.<br/> My questions are as follows:<br/> - What has changed between those versions of CODESYS that the described behaviour is observed?<br/> - How can this problem be remedied? Perhaps there has been introduced another function which I should be using?</p> <p>Best regards,</p> <p>Janusz</p></div>
