No communication with PLC

Manuelzes Posts: 99 Rating: (7)	Hi there i have a project in wincc flexible 2007. This is installed on a PC. The PLC has a Lean Module(CP 343 -1) for communication with the PLC. From the PC(flexible) i have tested the ethernet connection By the ping "adress" command. this works fine. The problem is If the PC(flexible) is in runtime it looks like there is no connection. The I\O fields are showing #####. The PG interface stands on ethernet and i can go online at the PLC by S7 managerwith the same ethernet conection. So the lean module works fine i think. Has anyone an idee of what i can do to get communication with the PLC by flexible runtime. Thanks for thinking, ME
