Hi. I have a GOT 2000 (GT2708-STBA ) with the version BootOS 1.17.00.R001.-Z i need to change versio more old.    How do I make the change?  

Hey Community, i would like to know if its possible to change the designe of the keypad in FTView which pop up at entering a numeric variable. There is a screenshot in the attachment. Thanks in advance!   Mit freundlichen Grüßen, Best regards Adrian Düringer  

Does anyone know if the Q50UDEHCPU is supplied with a battery for saving the RAM memory in case of power down? Also i read that you can put a second battery to back-up the memory stored in the Memory Card in case of power down. Is this also supplied by Mitsubishi or does it need to be ordered separately?

Hello! I saw there were some people on this forum who works with theese old PLC:s so i try here: Run onto this ancient Omron PLC - C20-CPU84E. Someone has not maintaned the battery enough.. and someone has not upgraded the machine. Stupidity. Now they want it running in three days. About 100+ I/O so its interesting to kick the old horse once more. I took the CPU off-site for investigation. I do not have the programming console etc but I am able to hire equipment from Omron if needed. PLC is said to have PROM. CPU is set to RAM ( dip-switches ). "PROM" Circuit has no programming window. It does not look like Omron EPROM images found on google. PROM chip has marking "Omron BP0J". * Application does not seem to need timers. Battry dead. LEDs: POWER ON RUN OFF ALARM OFF ERROR ON For testing - I charged the battery to 3.3+ V ( later resoldered the connector to a fresh CJ1W-BAT01, also gives 3.3V ) LEDs: POWER OFF RUN ON ALARM OFF ERROR ON Manual says it wants the battery alarm reset using programming terminal. Question: Run is lit: does it actually run? Or is it - it tried to run?. I tried manipulating some inputs and suspect the later. If it run - I could travel on-site and see how the machine behaves. If not - i have to get theprogramming terminal first. Thank you for any input.

I have several Mitsubishi Melsec Fx-1n 60 plc's that sometimes go for weeks without the equipment getting powered up when not in use. I know that it has the eeprom memory- does anyone know of a cheap effective hack to attach a battery or other device to the plc to retain the memory? I thought of attaching a battery backup unit from staples to it-any thoughts? The program operates ink pad printers which has several "jobs" in memory- (with parameter settings) it loses. This is leading to excessive set-up time when production is required. Any help is greatly appreciated!
