can you share the backup file ?

Hello Check attachment below. I change GM.gpj to Gppw.gpj. And i can open with GX Developer also with GX Works2 (Project --> Open Other Data --> Open Other Project) Also attached in.gxw file. GM.zip GM.gxw

It may help

@GoghieThanks for your answer. Just want to know if RTU to Ethernet converter can work. Anyway, Multidrop and TCP/IP from device i did earlier working without any problem. Thanks

Hello everyone, Need your assistance. I'm trying to read data from several modbus device via RS485 - Ethernet Converter (USR-DR302). I have 2 Temp controller (Modbus ID 3 and 7) and E&H Flowmeter (ID 15). Testing connection with Modscan32 works well. I can read data from all the devices. Now I want to read those data to FX5U PLC via ethernet (Modbus TCP/IP). I'm trying to use simple comm setting not works, use Modbus tcp (External device config ) also not working. Is there any way to read those 3 devices to FX5U ? Thank you

I wrote this just to share with all when I use Ver 1.100E, during online change I noticed my END ladder moved somewhere else between program ladder, some of ladder diagram also wiped ( erased). I open thread / topic earlier in this forum. Worst thing i did not keeping backup as usual. Just replace previous backup with newly downloaded from PLC. Just have a hope with older backup to re run the system. But good thing All system still running, but can't do any changes, until load new set of program. Rebuild program not working giving me this message "Error MAIN Program Conversion There is no END instruction in the end of program file. Please execute Rebuild All because inconsistency of program data might be found. 0x110E1B03". @GambitThank you for the information. @sczot Thanks bring up this in this forum

Hi All, I have a problem, below END ladder still having continuous ladder . What it may cause ? And is it possible to check date/time of last online change from ladder program via GXWork3. Thank you

Try to add gateway or router address in your PLC setting.

@Goran Vuckovic, yes it's true, can't see in that interval time @pturmel, We're planning to install new industrial inverter than can support full load system. @glavanov, I'm changing SD8008 to 100ms. Will see what can be happen in next power change. BTW, thank all for your support and advice.

@pturmel, we use local brand UPS, Blue Gate UPS, Yes, it's supply to load up to 4 hrs, without power grid, when grid available automatically switched to grid. @glvanov, thanks for the info, but main supply not less than 230VAC during switching. Will do another test.

Hello all, Currently I'm using FX5U-80MT/ES; with power supply 100-240VAC, In my work place we're not using power grid, but using gensets. The problem came when there's power changeover from one genset to other genset. FYI, gensets not run in synchronization. I'm using UPS to keep power available for plc to keep ON. But when running in UPS, PLC power is ON but not RUN. UPS no interruption, when power down min output from UPS is 230VAC, but PLC not in RUN state. Tested with several UPS same thing. Read on manual SM53 is to detect AC/DC Down. What it may possible cause PLC not in RUN state when I'm using UPS ? Thanks in advance.

Hi All, Is there any way or setting to limit of online program change conversion in FX5U ? Thank you

Yes, I'm using password for my PLC. All SLMP connection I'm using to connect to Weintek HMI. So should I add a Melsoft connection ? See picture below

Hi Gambit, Thanks for reply I'm using Gx work3 to monitor my plc, but when I run MX Sheet, connection cannot establish, unless I disconnect my GX work 3 both are from different PC. I'm using unmanaged switch to connect communicate 3 HMI and 1 Modbus TCP for other connection. See picture attached. I'm trying to figure out how can i modify my PLC in case I'm away but another PC logging via MX Sheet. Is it because I'm using password on my PLC ? Thanks & Regards.

Hi All, Just quick question, is it possible to access FX5U PLC from more than 5 PC at same time (Online monitoring) ? Thanks & Regards
