If you take away power (e.g. 30 seconds and then power on again) starts everything with no problems?

As i understand it they have connection master and slave,the strange is to start unit 1 i have to start unit 3 this think is first time happens this is how are my connections , Attachment IMG_1184.JPG (206 Downloads)

In the entries is also described to which adress the cpu can´t access. And these adresses are 10, 36 and 50. Now have a look in your HW-Config in your S7 HW-config and check where the adresses are used. At this module is the one where your error occurs. hope this helps,
