    Hello the machine is working since 8 years now and I never had this problem.It's not a problem of code as there's no modifications in the programm. As stated by BobB, it's should be the battery although the low voltage battery is not detected. I'll change it and let you know; Thanks to all for your different posts Best regards.

    Hello BobB, thank you for your reply The plc is turned off only during the week ends. The memory area used is DMxxxx I think the battery is ok because the "ERR/ALM" led is off

    Hello to all Since a certain time I've noticed that the parameters values sent to the plc via IHM are not anymore recognized by the plc I'm obliged to re-enter other parameter values to see the machine working fine again. The plc reference is: CJ1M CP 21 The IHM reference is NS10 What would be the problem,? Best regards.
