Suggestions for system configuration

  • The PLC Link station numbers of all other communication modules as well as Ethernet module should be different each other.

  • If duplicated station number is accessed in case of PLC Link, an error will occur in communication.

  • In case of normal operation, the mode switch of the CPU should be shifted to the RUN mode.

  • Use the communication cable of the assigned standard.

  • Check whether the communication cable is cut or short.

  • The use of other cable except the assigned may cause serious communication obstruction.

  • Tighten up the communication cable connecter to fix cable connection. Otherwise, the serious obstruction to communication may occur.

  • As the flexibility of a coaxial cable is low, it should be branched over 30 cm down from the connecter of a communication module. If you bend a coaxial cable perpendicularly or transform it unreasonably, the cable may be cut and the connecter of the communication module may be broken.

  • In case of a long-distance communication cable, the cable should be wired away from the power line or the induced noise.

  • If the ERR LED the communication module is ON, make sure and take action for the reason of an error in the module, referring to Chapter 9 Troubleshooting. If you follow-up as the manual, please call an A/S center.

 

Items Confirmed Before Test

The following is the explanation for the contents confirmed before you test.

Order of Test
The following shows the order from post-installation for a PLC to test.

 

Start

Inputting Power

· Make sure input power

· Make sure the connection of communication cable

· Input Power

· Make sure whether the power LED of the power is ON

· Make sure the state of the LED of the CPU module

· Make sure whether the state of the LED of the communication module is normal.

Programming :

· After programming in the CICON, to write the result to CPU.

Checking Sequence :

· Make sure the operation of the communication module according to the program.

Editing Program :

· If there is an error in the sequence program, edit.

Preserving Program

· To store the program in a floppy disc or a hard disc.

· To print the program and the list with a printer.

· To store the program in a memory module, if necessary.

Finish

 

If an error code of optional card is received in the CICON, and the ERR Led of an Ethernet card is ON or blinks, please call an A/S center.
