CJ1G cpu 42H clock problem

[Geir 4]

Hi, I just got this CJ1G unit at a reasonable price from ebay, and it seems to be OK, apart from a couple of issues: When I try to synchronise the internal clock, it reverts to some date in 1899, I didn't even know they had PLCs back then :) Also when I try to auto-build the IO table there is no response, it is connected in program mode. I can make the IO table manually and download it though, but the MAD42 is listed as C200 ASCII unit. The address is "right" and the green light is on, but I have not tried it with an actual input yet. I think this is a very early 'H as it has no version number, I use CX-programmer V9.2. Can the clock and IO problem be fixed? Geir Update: Now I can auto-build the IO table, but when the PLC is online, the MAD42s are still listed as C200H ASCII UNIT, could that be because the IO is much younger than the CPU? Have also tried setting the clock with the DATE function, and looking at A351 - 354 in the Watch Window, but still no joy :) Edited 6 Dec 2010 by Geir
