S7-315 2DP CPU

01/26/2012 12:06 AM

Hi every body

I face a problem with PLC CPU 315-2DP, when I insert MMC (512K) to CPU, it stopped with SF on and stop led flashing, reset of CPU not reset the error and also I can't go online with PG.

I should say this PLC is new and It is first time to be started.

I should add when MMC card is removed online operation is possible and i can transfer only HW config, no S7 blocks can transfered.

anyone can tell me what is the problem with this CPU?

It could be a few things, first check your "set PG/PC interface" setting (see Options menu in Simatic Manager).

Your problem could be as simple as it being set to MPI, but the MPI/DP port of your CPU is configured as a DP port (via the configuration on the MMC that you put into the CPU ...You may have to reset the MMC, instruction HERE....
