I have two S7 cpu 315-2dp (v2.6) and I tried to understand how to configure these two PLCs as Master> slave I couldnt find any topic related in programming and acccessing to slave cpu through the master one my questions are 1-in the configuration dialog of DP slave what is the difference between consistency type( unit, all) 2- what steps should i take to master cpu to identify the modules at the slave side 3-how can I monitor the data of slave cpu via the master one and how can i access to I/O modules 4-can anyone give me an explain how to deal with SFC14,15 or using the process image 5-when I freeze a slave module, how can i resend unfreeze and how can i take the inputs values 6-the distance between the two CPUs is about 1200m, so what is better to me ( usning fiber cables or profibus cable with repeater ) 7- how can I program the both cpus using OB1???? I hope if you give me a practical example to help us in understanding the steps to configure and programming both cpus with my respect .......
