Hi, I have a problem with serial communication (no protocol) using rs485 module, the received data is error. I'm using CP1L CPU, CP1W-CIF11 module as transmitter, and USB to RS485 converter as receiver. When I check the received data on PC, it's incorrect (bit error?). I just send 2 bytes data, 0x61 ('a') and 0x62 ('b'). My configuration: DIP switch CPU 4 = off, DIP switch CIF11 1 to 6 = on,on,on,off,off,off, 2 wire RS485. (I also attached the program and settings) https://postimg.cc/gallery/pr293Jc Could you help me to solve this problem? Thanks Program and Settings: Result:

Hello everyone, i am making a weight batching system , my system consists of 9 tanks each tank have a specific raw material , the user should be able to add a formula through scada system so he will be able to specify each weight of each ingredient to add to the formula. i have managed a connection between my weight indicator (pt650d) and my plc (fx3g) through fx3g232bd module (RS232 communication) , the weight indicator send data in ASCII to plc that we can show on the scada system . so how can i change the ASCII numbers that come from the weight indicator to Decimal number without changing the value so i can control a barrel that will add raw material from the tank to the scale untill it reaches what the user specify in the scada ??

Hello, I am rather unexperienced with PLC's but have some experience. I Currently have 2 Lexium ILS1 motors which we want connected over RS485. I have read a couple of manuals. I have found which format they want to receive their data and what the pinout of their pre assmbled cable is (which hasn't been delivered yet). I am currently unsure about a couple of things. The wiring the formatting of my data i'm sending, and the program. The pictured below show my motor (which runs when i connect it to the PC and run it using the software provided so it is in working order) and the PLC with option port (which i used to transmit data to another PLC, so again i can't blame the hardware for being at fault here). However when i connect the cable and try to communicated I Don't see the LED light up. I followed Lexiums guide on which pins to use. But i figured for good form i might include these pictures to be certain hardware is correct. Finally here is my program. I followed Omrons quick start instructions. But: my send ready flags never become high and the way data has to be formatted for these lexiums seems very labour intensive. But this is how i understood it needed to be done. Am i doing something (or a lot) wrong here? I hope someone can help me out here! If any further information is needed i'll do my best to provide it. Kind regards.

Here is a post that we recently completed on the Automation Direct USB to RS485 Adapter. The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular connector. This will accept RJ12 and RJ45 plugs. The USB-485M supports multiple baud rates and is USB V2.0 Compliant. Read the rest of the post...

Hi all, New to the forum. I've been pretty much able to do the things I wanted with Beckhoff, but now I'm finally running into a problem I can't seem to solve alone. I'm trying to set-up Modbus RTU RS485 communication in Twincat3, using an EL6021. I've implemented a sample program from the Beckhoff website, but can't get it to work. I've got the feeling I need to properly set up the EL6021 but most information on the Beckhoff website is about the KL-series IO. Does anybody have experience with this? The strange thing is that, when I enable the function to read some slave's registers, BUSY is set and remains set. No timeout is triggered. I don't have a slave connected yet but I would at least expect to see something on the output of the terminal, and then a timeout. I've bridged TxD+ and RxD+, and TxD- and RxD- and set 8000:06 of the EL6021 TRUE, half duplex mode enabled). A scope connected to TxD+ and TxD- shows nothing. Code added below. I've added a GVL called 'Variable_Configuration' with the following: VAR_CONFIG Main.MB.InData AT %IB0 : MB_KL6inData5B; Main.MB.OutData AT %QB0 : MB_KL6outData5B; END_VAR And then the MAIN: PROGRAM MAIN VAR bIoSyncMaster AT %I* : BOOL; MB : ModbusRTUmaster_KL6x5B; MBLedDriver : ARRAY[1..10] OF WORD; tmpExecute : BOOL; bError : BOOL; bBusy : BOOL; iErrorId: MODBUS_ERRORS; iNoDatByteRead: UINT; count: INT; freebyte: INT; TxError: INT; TxBlocked: BOOL; END_VAR MB( UnitID:= 41, Quantity:= 4, MBAddr:= 16#0020, cbLength:= SIZEOF(MBLedDriver), pMemoryAddr:= ADR(MBLedDriver), Execute:= tmpExecute, Timeout:= T#5S , BUSY=> bBusy, Error=> bError, ErrorId=> iErrorId, cbRead=> iNoDatByteRead); MB.ReadRegs(); count := MB.MBMaster.com.Buffer.Tx.count; freebyte := MB.MBMaster.com.Buffer.Tx.FreeByte; TxError := MB.MBMaster.com.Buffer.Tx.Error; TxBlocked := MB.MBMaster.com.Buffer.Tx.Blocked; tmpExecute:=FALSE;

Hi everyone, i'm just starting to learn plc mitsubishi. Today i got a problem about picking module plc. I want to communicate between FX3G and R04EN through ethernet. When i research it said only FX3U-ENET module can be connect to FX3G. But when i say it to seller, he said FX3U-ENET-L is a new update, and it can connect to FX3G @@!. I don't know if what he said is true or not, can you guy give me some advice? The picture below is the documentation related to these 2 modules. Thank you very much and have a nice day. ^^!!

Greetings everyone, I have a TIA V16 project in which I set up 7 drives to communicate with an S7 1500 controller via RS485 using USS protocol. The drives are Simatic V20s daisychained to the bus and are properly terminated with resistors. I use the USS DRIVE CONTROL 31 function block for each drive all located in a single FC and all using the same single instance DB as recommended by Siemens. I then call this FC containing the FBs every 120ms from the MAIN OB. I then call the USS PORT SCAN 31 function in a cyclic OB set at 70ms cycle time. In each V20 i use PZD word length of 2 and a PKW of 4. Both setpoint and commands are sent through USS. What I have observed is every time take out incoming power to any one of the VFDs, the rest of them get F72 comms error and fail to communicate with the PLC. Is this behaviour normal? What causes it? I use an RS485/ 422 PtP BA module sending data at 19200bps. Strangely enough it doesn't show any fault even though the diagnostics interupt setting is enabled on it. What I noticed is that as I was setting up the VFDs one by one, the F72 fault on the BOPs only pop up on an already configured drives. So, the VFDs that hadn't been commissioned yet for RS485, but were already physicaly terminated/ connected to the PLC, didn't fault the bus when they were powered down. They only faulted the bus upon switching them off only after RS485 activation (post commissioning).

Hello, Can I get a laptop usb bluetooth receiver and a usb-> mini usb adapter and plug the bluetooth receiver into the programming port of a fx3g PLC for wireless melsec software connections? Seems like it would be a nifty little addition to any panel. https://www.amazon.com/Bluetooth-Adapter-Wireless-Compatible-Computers/dp/B071WKP37Q/ref=asc_df_B071WKP37Q/?tag=hyprod-20&linkCode=df0&hvadid=309751315916&hvpos=&hvnetw=g&hvrand=14775611605752866986&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9058221&hvtargid=pla-761431569272&psc=1&tag=&ref=&adgrpid=67183599252&hvpone=&hvptwo=&hvadid=309751315916&hvpos=&hvnetw=g&hvrand=14775611605752866986&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9058221&hvtargid=pla-761431569272 https://www.amazon.com/Ksmile%C2%AE-Female-Adapter-SamSung-tablets/dp/B01C6032G0/ref=asc_df_B01C6032G0/?tag=hyprod-20&linkCode=df0&hvadid=309833041189&hvpos=&hvnetw=g&hvrand=3896490646336226374&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9058221&hvtargid=pla-567647287320&psc=1

Hello, We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible. thanks.

I have a Siemens HMI 6AV2 124-0MC01-0AX0 in my machine. I want to clone the display on the HMI to PC/Laptop. My question is: 1. What software that I need for this task? 2. What kind of interface that I need between the HMI and PC/Laptop (for example ethernet cable, etc)? 3. Do I need to communicate with PLC connected with HMI or can I just connect with the HMI? Thanks in advance for the answer.

Hello I have a wago PLC and i try to communicate to a device through RS485 using the module 750-652. I tried using the WagoAppCom library and came up with this code But i always get errors regarding FB_init block. I though the instance would be automatically matched. I still can't see how to resolve this as Wago library documentation is very poor and contains 0 examples. Has anyone else solved serial comms problems?

Hello, I need to connect multiple barcode readers (SICK CLP510) to a PLC (FX3GE-40M) for a university project. I need a minimum of 3 bar code readers, but only have one operational, connected via an additional modul for the use of rs-232. The only other port I can use is a miniDin 8, which is a build-in rs-422 port. Because this is a university project, it needs to be as cost efficient as posible. All the readers are CLP510 (pin-out attached bellow) Thanks Becky Pin_out___wire_colour___signal_comparison_CLP100_CLP510_CLV60x.pdf
