Hey there. 

i am trying to work on this same. I tried to write the parameter p2599 using 1500 plc but then i was using wrrec block. And it did not work. Can you explain me how did you write parameters using sina_pos block. if i use mode 5 in sina_pos block, then the actual position is becoming 0. But then what should i do if i have to write a value 100 to the actual position using the same block? 

Much appreciated.

Thanks and regards

Athish
