Battery Change in TSX Nano (Modicon)

5 posts in this topic

Can I safely change the battery in an old Telemaecanique Modicon TSX Nano PLC that has lost its operating program due to a low battery ?. This is from a Heller oven and I need to somehow get the device re-programmed but first need to replace the battery. Thanks in adv. Cb

You probably could open it and change.....since the program is gone in any-case. Edited by cHud

Thanks Sparky --- dont understand the logic unless there is more than one program and there is some way of telling the micro which program to load at startup. Warning :- Anyone out there using Heller ovens should take all the necessary precautions like video'ing the PLC's during start up etc. as they wont give or sell you the program - you need to buy a new PLC or send this unit back for programming at 1/2 the cost. What a HELL........er ova waste of money and time.

The nano plc is an old plc. Its redundant. Is this a new machine?

The program isn't lost by a battery. As it clearly shows in the text copied by cHud, the program is in EEPROM. You maye have had more of a hardware failure than a dead battery.
