Problem with half of DO in CPU313C-2DP (313-6CE01-0AB0)

After the first test it appeared that half of outputs isn’t working, those with the address 124.x is not giving high status and those with the address 125.x is working correctly. I already did master reset and check the power supply on DI/DO module. What’s more the current on outputs that aren’t working is about 0-3V the same as on working ones (125.x) in low state.

	If this information really helps, you could use the Rate function. Best Regards.
