<div class="markdown_content"><p>OK, thanks for your comments, it sounds like it should work. I'll see if the issue reoccurs.</p></div>

<div class="markdown_content"><p>Since both FB's are instantiated separately, they have individual memory allocated. None of that memory is shared by design. </p> <p>Only your external glue logic seems to be the issue since you use a single instance of the flipflop on both HTTP request FB's?</p></div>

<div class="markdown_content"><p>Hi,</p> <p>Unfortunately I can't upload full projectarchive, but I've attached screenshot showing the 2 different instances (hTTPClient_0 and hTTPClient_1), based on the single Codesys example. I'm using HTTP client ver 1.0.1.2 in Codesys V3.5 SP15 Patch 4 on a Festo CPX-CEC-S1-V3. </p> <p>I hope that helps. I haven't been able to recreate the issue so perhaps it was network fault. I'd just like clarification that two instances of the client block should/shouldn't be acceptable.</p> <p>thanks</p></div>

<div class="markdown_content"><p>Hi,</p> <p>Before we , the community, can help you further you should provide exact more details on architecture and software setup, otherwise we are just guessing. Can you share your software project as a projectarchive?</p> <p>regards</p></div>

<div class="markdown_content"><p>I'm using the Codesys HTTPClient function block. I have two instances in separate CFCs, each talking to a different IP address (2 x Raspberry Pi). It's been working ok, but yesterday the Codesys program was stuck waiting for replies from both devices.</p> <p>Sanity check: is it ok to use multiple instances of the HTTPClient to talk to different IP addresses? Or do I need to use only one instance and somehow manage the different requests so they can't be simultaneous?</p> <p>thanks</p></div>
