DanT Posted June 5 Report Posted June 5 Hi; The PLC has an internal battery to hold RAM memory when the PLC is turned off. If the program was downloaded and stored in the eprom it would boot. If the program was NOT Burned into the eprom, and left only in RAM, and the battery has failed, then the program is lost. It appears that the battey may have finally died ( they are good for 7-10 years ) and memory is lost - along with the program. The PLC appears to have an old OS ( Operating System) - 2012 - How old is the machine ? Contact the machine builder and inquire if they have a replacement PLC , or can provide the program for upload. The V130 does have a Micro SD Card slot and there is a way to have a program restored via a Micro SD Card.. Also obtain a Battery CR2450 - reputable brand - and install it in the PLC. PLC has to be taken apart to install the battery. Note to any programmers reading this : Have a line of code in tha ladder to monitor the Battery and a Message on the display when the battery is failing ( SB 8 -- VisiLogic) DanT
