Precautions during installation of Profibus-DP module
Station number in the range of 0~99 is available for 2MLL-PSRA, and station number in
the range of 0~98 is available for 2MLL-PSEA.
The following precautions must be taken during the installation of the 2MLL-PSRA and
2MLL-PSEA modules.
−
Verify the basic factors necessary for the system configuration and select the
proper communication module.
−
Prepare the cable and accessories such as tab, terminal resistance, and so on to be
used for this communication.
−
The station number of all other stations including this module should be
different. If it is connected with more than one station number, it may cause the
communication error.
−
In case of operating with normal communication, the mode switch of master
module should be at RUN mode.
−
For communication cable, the designated standard cable should be used. If not, it
may cause significant communication obstacle.
−
Before installation, verify if the communication cable is cut off or short-circuited.
−
Tighten the communication cable connector completely and fix the cable
connection tightly. If the cable connection is not complete, it may cause significant
communication obstacle.
−
If the communication cable is twisted or if the cable is not connected properly, it
may cause communication error.
−
In case of connecting the long distance communication cable, the wiring should
be far from the power line or inductive noise.
−
Do not remove the PCB from its case. It can result in damage or an abnormal
operation.
−
If LED action is abnormal, refer to section Troubleshooting for causes.
−
Install the Profibus-DP module when the status of PLC power is 'OFF'.
