convresion s5 to s7

hello every body,my first question is what comes fb250(RLG:AE)and fb251(RLG:AA),[analog i/o] in to s7.
second:
the configration of OB13 in DB1 is 100ms,but in OB22\fb100 using the comand T BS97 the time of OB13 becomes 200ms.what shall i do in S7 to configurate the periodicity of OB13?

hello dear aymen
for your first question
you just configurate your plc "hard") because in step 5 you configurate your AI and AO manualy but in step is automatiquely configured .if you loock th output of fb250 is integer and you will enter in fb 105 /feb106 as your programme
