I am using IM151-7 CPU, DP master card,power module and a 8DI module. When i download H/W configuration of above hw in 151-7 CPU it doesnt goes to run mode.If i remove power module and DI module it goes to run mode. If i remove DP master card and use IM151-7,PM,DI module then also it works fine.But it doesnt goes to run when i use all four things at a time.

i am attaching hw configuration an module information here...

Kindly help...
