Hi, If their are spare area vacant in between module station to other station. For example station no 1,2,3,4,5,6,7 in use and then 11,12,13,14,15 n so on... Then via using dip switch you have to set station no. 8,9 and 10. If all location filled then increase total no. of station counting let suppose now 33 station then you have to change 35. (33+2). For addressing set total no. of station in parameter setting after check parameter. if their is no error. then check X/Y ack. in CC-link parameter. Scroll down you seen after X/Y 80 you shown some entry filled. And finally last 2 channel station no. 34 & 35 station IO addressing.
