  2. when doing program, sometime really need a long period timer, I used to use RTO retentive timer, that can make 69 minute time delay. but recently I got problem. the production runs 24x5 hours, I have to keep one of my program function to monitor the equipment fault, I could not get the plc time by using GSV. the system time doesn't work. (all the other production lines, the system time work well, only this line 1769-L30ER 5330ER) By calculation, one day is 24x3600 seconds, six day is 144x3600 second, so I use CTU to count the every second, and use the CTU.ACC as relative time record.  If the production line runs five days with no stopping, the counter will count to 120x3600 second, it's long enough to keep the monitor on. once the line stops, reset the counter to zero. waits for next starting up.     S.

    Thanks, Sparky, I am attaching off-line equipment to main production line, looking for wireless thing. good to know it had been discontinued. I think I have to run cable to link them.

    Had anybody use Omron we70 AP in the job?  How is it work? I got old production line, I am tire to run cables to link equipment, I used smc wireless module before, it works well, but it's only suitable for their valves control. anybody use this kind of module now?
