m.libeau Posted November 25, 2014 Report Share Posted November 25, 2014 Hi ! I just want to know if it's possible to replace a battery on a V570 without turn off the power ? Thx. 1 Link to comment Share on other sites More sharing options...
Eyal Koren Posted November 26, 2014 Report Share Posted November 26, 2014 Hi, Not only it is possible to replace the battery while the PLC is powered, it is also recommended. This way you can keep your system running without losing any values stored in RAM. Link to comment Share on other sites More sharing options...

cataliz3er Posted April 12, 2017 Report Share Posted April 12, 2017 What type / model of battery is required? I can't seem to find this information in the Technical Specifications or in the Installation Guide. Thanks! Link to comment Share on other sites More sharing options...
R.Mozes Posted April 12, 2017 Report Share Posted April 12, 2017 Hi, The battery type to all models (except JZ20) is: RENATA BATTERY,COIN,2450,3V,LITHIUM http://www.renata.com/fileadmin/downloads/productsheets/lithium/3V_lithium/CR2450N_v06.pdf Unitronics part number: 160200362 I hope it helps.

Exit5w Posted April 23, 2020 Report Share Posted April 23, 2020 Is it possible for a low battery to cause analog input fluctuations? Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted April 23, 2020 MVP 2023 Report Share Posted April 23, 2020 No. The battery only backs up the RAM when the power is off. Those are typically from noise in the system or the DC power supply regulator going bad. What exactly is happening? Joe T. Link to comment Share on other sites More sharing options...
Gugun Posted May 28, 2020 Report Share Posted May 28, 2020 The battery goes low in a Unitronics V570 at my printing machine, I want to replace the battery with the new one (Renata CR2450N). Is it very very safe to replace the battery when V570 powered on, without back up data before? How many seconds can we replace the battery without losing data when the V570 is on (because I don't have a PLC program). Link to comment Share on other sites More sharing options...

I don't think it's safe EVER to run a PLC without some backup precautions haven been taken. Eventually something will happen requiring need for a backup. 9 hours ago, Gugun said: How many seconds can we replace the battery without losing data when the V570 is on (because I don't have a PLC program). The battery is only used when the 24V power is disconnected from the PLC. If the PLC is powered on, then there is no time limit for replacing the battery.

MVP 2023 Ausman Posted May 28, 2020 MVP 2023 Report Share Posted May 28, 2020 Gugun, are you able to connect to the 570 using Visilogic? It's not difficult to do. Get Visilogic at the link and once installed look up the help file for "PC" using the index tab, which will describe the connection process. https://unitronicsplc.com/software-visilogic-for-programmable-controllers/ In theory the PLC program is "embedded" into the PLC, but the original programmer may have restricted access to extracting it from the unit. However, the operational data which you may have "tailored" to your operation can be saved into a file for reloading if lost. But it needs you running Visilogic and connected to the plc. Advise if you can do this. cheers, Aus Link to comment Share on other sites More sharing options...
Nicolas BGI Posted May 29, 2020 Report Share Posted May 29, 2020 Hello Gugun, Another possibility we do with our team on "sensible" PLCs is to make a full backup on a microSD card before. We have V430 here, and you cannot plug the 24V when removing the battery (mechanically impossible) so the backup is important. It requires to know the Service menu password and to have the SD Password defined in the project first. Nicolas Link to comment Share on other sites More sharing options...
engahm78 Posted June 10, 2020 Report Share Posted June 10, 2020 hi there i am facing problem with The V200-18-E3XB during replacing the battery someone mistakenly turned off the power and we got this screen after power up, kindly help asap Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted June 10, 2020 MVP 2023 Report Share Posted June 10, 2020 You will need to re-load the program. It is no longer in the PLC. Link to comment Share on other sites More sharing options...
engahm78 Posted June 10, 2020 Report Share Posted June 10, 2020 i have the program on my laptop ,but i need to know the configuration of the usb communication cable to download the program again. Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted June 10, 2020 MVP 2023 Report Share Posted June 10, 2020 Are you talking about serial communication settings or what? Link to comment Share on other sites More sharing options...
engahm78 Posted June 10, 2020 Report Share Posted June 10, 2020 i made serial communication cable using rj11 and 9 pin connector as the catalogue configuration , but when i connect it i couldn't get to plc to download , i faced 2 problems 1- i use visilogic 9.8 when i connect it said that my os is old and need to be update 2- then every time i make connection there is error that the connection maybe broken or com port or baud rate is wrong or other reasons. what i do to download the program also i tried rs232 to usb adaptor but same results Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted June 11, 2020 MVP 2023 Report Share Posted June 11, 2020 You will have to update the OS if you're running Visilogic 9.8. 1. Are you plugging into port 1 on the PLC? 2. When you press "Get OPLC Information", do you get any response? Joe T. Link to comment Share on other sites More sharing options...
engahm78 Posted June 11, 2020 Report Share Posted June 11, 2020 what i do first update os or check OPLC ? Link to comment Share on other sites More sharing options...
engahm78 Posted June 11, 2020 Report Share Posted June 11, 2020 could you please send me documents with the right configuration for pc communication cable and jumper sittings for RS232 , noting that i will use usb adaptor. Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted June 11, 2020 MVP 2023 Report Share Posted June 11, 2020 engahm, don't do the O/S update just yet. I would not use 9.8 as your Visilogic program. The O/S in the plc will likely match the program you have on your laptop. Changing the O/S may make the program not work correctly. Going on O/S to Visilogic versions, you should be trying to use 9.4.0 which is not readily available, but you can likely get by on 9.3.1 which is here: http://www.unitronicsplc.com/Download/SoftwareVersions/Visilogic/VisiLogicSetup_931.exe Change your Visilogic installation to that version and see how it goes doing Joe T's suggestions. I think you are still going to have comms issues, as it looks like you may have an adapter that doesn't do all the serial communications correctly. Ensure that you have the wiring as follows, which is in the Help file anyway. cheers, Aus Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted June 11, 2020 MVP 2023 Report Share Posted June 11, 2020 For your other request about jumpers etc. find the correct information for your plc in all the literature available in various areas of https://unitronicsplc.com/support-technical-library/ Vision Hardware. cheers, Aus Link to comment Share on other sites More sharing options...
Mbc Posted March 30 Report Share Posted March 30 In the manual for v570 the backup battery lifespan is typically 7yrs at 25celcius. Is this not in standby? - if this is correct and if the plc is powered down, how long would the battery last? Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted March 30 MVP 2023 Report Share Posted March 30 I would think that if the PLC were to be powered down for an extended period of time the smart thing to do would be to replace the battery immediately upon power up. The batteries are cheap, readily available, and extremely easy to replace. Link to comment Share on other sites More sharing options...
