Good day all. I have a SLC500 that is controlling an air flow rig. The HMI is a PC using a home-made program using VB6. I have no experience with Visual Basic, neither does anyone else here. I have been tasked with purchasing a new HMI for GUI and SCADA to replace it. I would like to know if someone familiar with VB might be able to help me locate the addresses for the tags that are used. The RSLogix 500 program at the PC does not have descriptions, tag names, nothing. It is a relatively small system so the I/O is easy enough to figure out however, the recipe info is coming from MSACCESS database, and communication between PC and PLC is via RSLinx DDE, serial connection. Thank you
