8.2 Startup
Each segment should be connected by vertical resistance. If there is no vertical resistance, it may
cause the error in communication. After connecting the communication cable, apply the power and
observe the LED active state and if it is normal action, download the relevant program to PLC by
GMWIN and execute the program.
8.2.1 Notices in system configuration
1) High speed link station no. of all other station including this module should be different. If
connected with overlapping station no., it may cause the error in communication which results
in preventing the normal communication.
2) Use the communication cable with the designated specification. If used the cable except the
designated one, it may cause the serious obstacle in communication.
3) Before installing communication cable, check if the cable is disconnected or cutoff.
4) Tighten the communication cable connector strongly to fix the cable connection tightly. If cable
connection is not stable, it may cause the serious obstacle in communication.
5) In case of connecting communication cable in long distance, the cable in wiring should be far
from the power line or inductive noise.
6) If LED is not active normally, check the trouble cause by referring to ‘CHAPTER 9, Trouble
shooting’ of this user’s manual and if the trouble continues to happen, please contact to A/S
center.
