Hi. I’m currently using RobotStudio on site, configuring EPS settings. However, I’m having endless problems connecting to the robot, sometimes I can click add controller, and it works first time without any problems. Others, I have to reconfigure my ipv4 settings to either a preset I.P address for example, 192.168.125.5, and sometimes I can have my settings as obtain I.P automatically. There seems to be no common fault and I am at my wits end as to how to guarantee myself a connection, eventually I can connect to the robot through persistance, but it’s really holding me up in my work. Does anyone know a way around this? Thanks, Tom. ---

Tom, Make sure that you are doing the connection through the service port and not the network port. I had problems just like you are describing not connecting through the service port. The other thing I ran into was my Antivirus/Firewall program (Norton’s) was blocking me from making the connection. I had to go in and configure it to trust RobotStudio.
