Not yet, but I 've ordered on that for spare module. Thanks you!

My system is working normaly with a new Lk201, One again, Thank you so much for your help!!

PLC was running normally untill the cpu unit suddenly off then cannot turned on. It was replaced by new one, the ROM unnit was moved to new CPU. Then PLC run without connect to computer. Is there anny thing form CPU unit or ROM unit that control Lk201 function such as clock, activate signal..? Thank you!

Thank you! I've used 5 Volt, 9Volt and 12 volt as you suggest, but RCV doesn't come ON. Both of them could be bad!

Thank you for your reply! - The PLC seem to be ok but the connect to computer. LEDs on the I/O light correctly. Only led "Run" on the CPU and on the LK201 light. - When I try with the Host Link in the blank slot, everythis is the same - When I remove all the modules from the rack and try the Host Link in another slot, only led "run" on lk210 light, cannot connect cx-programer, on the cpu led "run" light led "error" flashing ( alarm) ( Could be incorrect I/O table)

I also tried with this cable LK201 Coputer 2------------2 3------------3 7------------5 (4-5). .(4-6)(7-8). But there's still no RCV light Please help me!

The BP :c200h-bc081-v1, LOT No:2563 Units mounted: |NA|ID217|ID217|ID217|ID217|ID217|OC224|Lk201-v1|CPU21(C200h-ME832 EERom) EX: |OC224|OC224|OC224|OC224|OC224|OC224|OC224|Lk201|PS221 The cable: (running for long time) Lk201 Computer 2------------2 3------------3 (4-5 ) . . (7-8) 7------------5 (6-8-20) . . (1-4-6) There's no RCV light Thank you so much for your kindly help!

I have checked the cable carefullly, the cable should be ok. Is there any configuration on the EEROM of CPU21 that make the hostlink cannot receive anything? Can I move the host link to other slot of BB? Thank you!

I will check the cable one more time!' Thank you!

Thank you for your explaination, I have tried with pin 3 on the back OFF but still cannot conect. ( only "run" led on the host link light) I also monitor output of the program by connect to an other computer through rs232, hiperterminal and see that the program still sending " @00RR100002043*" ms, one per second. Is there any control from the CPU 21 that make LK201 cannot recive anything?

By the way, Can i connect directly to CPU programming console port by CX-programmer? If possible, which cable I have to use? Thank you!

The DIP switch front are 0;0;5;2 back are off;off;on;off;0v Please help me!

Thank you! The dip witches in the host link are correct but still not connect. I have replaced c200h-lk201-v1 by c200h-lk201 and everything is the same. By the way, can you tell me the different between lk201-V1 and lk201 ?

This is C200h-CPU21-E2 LOT No: 0683 I cannot find any DIP switch on this CPU

Thank you for your reoly! The Software is a monitor software that read the Input of PLC then show to the screen, I already tried to connect Cx-programer to this PLC but cannot I replaced the CPU of the PLC, keeping the ROM-MR433
