6.1.2 Notices in installing Profibus-DP module
Profibus-DP Smart I/O can set max. 126 stations. (including master)
But forXGL-PSRA, station number 0~99 is available. For XGL-PSEA, station number 0~98 is available
(1) Check the basic factors necessary for the system configuration and select the proper communication module.
(2) Prepare the cable and accessories such as tab, terminal resistance etc. to be used for this communication.
(3) The station no. of all other stations including this module should be different. If connecting with double station no., it may
cause the communication error.
(4) In case of operating with normal communication, the mode switch of master module should be at RUN mode. If
changing the mode switch of master module in the status that other stations are in communication, it may cause
significant communication obstacle with other stations. So, special cares are needed.
(5) For communication cable, the designated standard cable should be used. If not, it may cause significant communication
obstacle.
(6) Check if the communication cable is cut off or short-circuited before installation.
(7) Tighten the communication cable connector completely and fix the cable connection tightly. If cable connection is not
complete, it may cause significant communication obstacle.
(8) If the communication cable is twisted or the cable is not connected properly, it may cause communication error.
(9) In case of connecting the long distance communication cable, the wiring should be done far from the power line or
inductive noise.
(10) If LED action is abnormal, check the trouble causes referring to this manual Chapter 11.
“Trouble Shooting”. If the
problem repeats after taking the action, contact customer service center.
(11) Install this communication module in the status that PLC power is
‘OFF’.
(12) After finishing the communication cable connection, put the power ON and check the normal action in the LED action
status. If it is normal, download the corresponding program into GMWIN for GLOFA series and into KGLWIN for
MASTER-K series and run the program.
