  1. Hi Aus! Thank you so much for your response! I got it working now, you're right. I just needed to add buffer time. Thanks!
  2. Hi! I am having issues using the Protocol Scan TCP/IP function block and I was hoping someone could help me (I am a beginner visilogic/ladder logic user). I have already configured socket 0 and the Protocol Configuration to the correct IP address and it is configured correctly. I know this because the Protocol Send TCP/IP function block works. However, I cannot get the Protocol Scan TCP/IP function block to receive any messages. What I am doing is sending Modbus commands to a non-PLC device using the Protocol Send TCP/IP function block and it works. But each of these Modbus commands also have a Modbus response, which I am trying to get using the Protocol Scan TCP/IP function block. I have tried placing the scan block directly after the send block and I have tried having the scan block after a constant set direct contact. I have tried scanning for the message I was looking for and I have tried scanning for any message at all. But all of these attempts did not change the MB Message Received to a 1. Please help! Thank you!
