Hello, From modbus, Im reading a HEX variable in the data register D0, as it is a 32 bit variable, the second part is saved in D1, then I get: D0: BE62 D1: 31D7 The value that I should obtain in float is -0.2208932 as I obtained setting BE6231D7 in online Hex to float converter and this agree with what I'm reading on the flowmeter. The problem is that when I try to change the data type from channel to Real on CX programmer I obtain a different value, also the registers are not sort in the proper way, instead they are sort inversely 31D7BE62, and obviusly the obtained value is completely different. Also instead of Hex, I want to display the decimal, or floating value, is there a way to do this? I'll attach some captures.

Please could you assist with the software required to download data tables from 4 off DIRIS A10 Multifunction Meters into TM221CE40R Logic Controller via TMC2SL1 Comms Cartridge using Modbus Protocol over RS485. I have downloaded the Modbus tables from Socomec but not sure how to get these into the PLC. I would really appreciate your help in achieving this. I am using EcoStruxure Machine Expert - Basic to program the PLC & DAQ Factory Developer Release for my Touchscreen.

Hello, I have been so many days trying to comunicate the multiway software trought a serial usb converter with the SCU31 device, using a omron function block to read a holding register, but I can't achieved it. Now Im receiving some frames on multiway, but there is always some errors. I was wondering if somebody in here that have worked previously with modbus and omron can be able to help me in how to configure everything corectly to be able to read the value from multiway, on the plc, and where is this value saved. I'll upload some captures to show what I have done till now.

How can I read a variable trought Modbus on the PC? RS485 Modbus and Omron
alpr_94 posted a topic in CX-Programmer
Hello, I have been reading some post on this forum about Modbus and omron, but it has been complicated for me communicate an Omron PLC and a computer just to test the Modbus communication. I have a PLC OMRON CJ2M-CPU32 20K with a CJ1WSCU31-V1 that I want to communicate trough Modbus first with a computer just to test that is everything working ok. How can I do that? How do I need to configure the units, switch? Nodes? Im using multiway, and CX programmer, I already downloaded Macro Protocol to the PLC, but by now the only thing that I get is RD1 flashing when Modbus poll software is active on the computer, but this software says timeout, and don’t receive packets… I have used the easymodbus excel file to create the code to communicate the PLC, but as I see isn’t working. Does somebody in here have got to connect a plc to the computer with this easy modbus file? How is the proper way to use it? Or there is a better way to use Modbus in Omron? I’m really desperate. -
M241 - Modbus TCP - problema reading analog inputs (#300001)
horvatmiha posted a topic in Modicon / Telemecanique / Schneider Electric
Hello! I am new at programing PLCs. I am using TM241CE24R PLC with TM3AI4 analog input module. I can successfully read temperature from 4-20 mA sensor. I want to communicate with my PC (SCADA) via Modbus TCP. For testing purposes I am using CAS Modbus Scanner. I can read digital inputs, coils and holding registers successfully. Problem is that I can't read analog inputs (#300001 etc.). I have nothing defined in GVL list. Is this causing problem? I also don't have any Modbus TCP Slave device in Ethernet_1. But how can be all the other registers read successfully? Please take a look at screenshots below. Also check Error message from CAS Modbus Scanner. Where is problem? Please help. Thanks in advance! -

I have got a FX3U-16M and -32M PLC and trying to connect with Moxa NPort 5130A serial device server to work with a scada. It seems that i dont get the modbus to communicate. I have tried the 110 ohm, 330 ohm and open setting on the device. I am making use of a 2 wire system. I have configured both the channel 1 and channel 2 of the PLC to work with MODBUS 485. i have written a program like follow M8411 ----------- Move H1087 D8400 ----------- Move H1 D8401 ----------- Move K2000 D8409 ----------- Move K400 D8410 ----------- Move K10 D8411 ----------- Move K3 D8412 ----------- Move H1 D8415 ----------- Move K100 D8416 I just need to test if there is communication from these cards. i have got 15 cards to test. Any other help will also be appreciated.

hello I have been forced to replace a TWDLMDA20DRT with a Schneider TM221ME16R. the plc is a slave but I am having trouble getting the Modbus data exchange to work like it did with the old plc. I have setup the serial port to use Modbus etc etc and I played about with the read_var FB but this wasn't required in the old plc so im confused as to why I would need to use it on the replacement. I have come across another FB send receive message but again i'm not too sure if this is required. the master plc uses the msg2 and exch2 command. I believe I am just missing something very simple here. Lighting Panel - Old_PLC.twd Lighting Panel1 - Master -.twd Lighting Panel - Pillar5 -.smbp

Hi dears I have one CP1H CPU and CIF11 option port on it. CP1H will be slave and I want to use modbus slave function. (ABB is Master and CIF11 is slave) I check the logic with modbus poll and i didnt have any Receive from CIF11. I have some questions: 1- which terminal in CIF11 must be used? SDA+,SDA- or RDA+,RDA- ( I use Modbus RS485 two wire ) 2- I mounted CIF11 on port 2 and in setting of port 2 I Choose RS-232C in Mode, Stop bit=1, parity=none , Data bit=8. is there another settings? 3- I set CIF11 DIP switches ( ON,ON,ON,OFF,OFF,ON) is it OK? 4-I change 4,5 DIP Switches to ON in CP1H. Thanks

From @SamuelT Please, I want to know if you know how to communicate two plcs omron CP1H (master) and one CP1L (slave). The master CP1H will send 10 DM memories to slave CP1L. Now I have this configuration: CP1H MASTER PORT: CP1W-MODTCP61 MASTER IP: 10.150.1.5 SLOCK: 1, DIP SWITCH PLC # 4 = OFF CP1L SLAVE PORT: CP1W-MODTCP61 SLAVE IP: 10.150.1.1 SLOCK: 1, DIP SWITCH PLC # 4 = ON I use the modbus RTU function blocks, but the master PLC does not communicate or send the DM memory values to the slave PLC Thank you very much for your reply if you have any example program it helps me a lot MRTU_CP1L SLAVE.cxp MTCP CP1H_MASTER.cxp

Hello Everyone, Need help with reading channel data of FX2N-4AD with FX3U Cpu. I have added all the logic and it works also. Problem is that, FROM function stop reading/fetching data from FX2N-4AD after some time i.e couple of hours and value just hang. Like 502 or something, untill you reset the whole PLC. What could be the problem. For the further info, -I have connected the FX2N-4AD on the right of fX3U-64M. -There are two extension blocks FX2N-16EX and FX2N-16EYR also added to the right of FX3U-64M -Order of mounting....FX3U-64M > FX2N-16EX > FX2N-16EYR > FX2N-4AD > FX2N-4AD I have tried using the 2nd special module connected at the end, but It showed similar problem after few hours of running. THis shows that both Special blocks fx2n-4ad are okay. There is something wrong with PLC maybe? Please help

Hi, I want to set communication between ABB CI853 Modbus Master module and Mitsubishi RJ71C24 module. I tried with predefined protocol (you need to set slave address, but ABB is master), also with non-procedural (with G_Output function block), but without success. I tried connect ABB with QJ71MB91, and it worked because you can then set slave address and a station number, and this can't be set with RJ71C24??? If someone had a similar problem, I'll be grateful for sharing a solution. Best regards

Greetings, I'd like to know how I could configure 2 HMI Kinco with reference MT4434T. I have a PLC with modbus485, a PC with USB-RS485 conversor and 2 HMI Kinco. The PLC have 1 on modbus direction, PLC have 1 and I guess that HMIs would be 3 and 4. When I work with PC + PLC + 1 HMI Kinco, everything its ok. When I tried to connect other Kinco HMI, the connection between all devices stuck. I'm tried many combinations on modbus configuration, station number but I cannot make the modbus net works. Thanks.

Hello people, i need some help. I'm Trying to create a simple program that stores some input's such as Temperature, Production and Velocity (amongst others) in a machine , so that later i can send them to labVIEW via MODBUS RTU, the problem is i can't send anyregister i want, there was an old program we saved from the PLC that does store them, but uses the registers 199, 519 and 999 (the program reads 50 registers and 20 registers respectively from each register. I then tried modyfing the old program due to my problem to communicate the new one, and out even modyfing the registers won't work, i'm i missing something?, does the HE-XE102 Horner PLC have a specified number of registers that can be read or sent via MODBUS. Appreciate any answer you guys could give me, Thanks for your attention.

Hi all, I want to connect FX3G PLC to a network. So I have installed FX3U-ENET-ADP to the left side of the FX3G PLC using FX3G-CNV-ADP. Can someone help me how to change the IP address of the PLC according to my network IP address (let us take it as 192.168.0.50). So now I want to configure the PLC's IP address as 192.168.0.30. I tried using the FX-Configurator-EN but I could not establish a connection with the PLC through it. Here are the snapshots of the process I followed. But when I do the 'Connection test', I'm getting the following Error message. I tried to connect with both Serial port & USB. But it is showing the same error. I'm aware that there are lot of discussions happened in this regard, but I could not find the solution part to the problem I'm facing. Kindly guide me please. Best Regards, Vijay

Hi: I`m trying to figure out how to log data from my plc fx3u-16m to my data logger fx3u-cf-adp but in a certain period of time. I explain my self: Manuals explain very well how can I write data in my data logger and generate tables but I cannot find how I can set the time period when I want to perform that. I would like to set a data log every two minutes and when errors occurs. Thank you so much.

At this moment I was asked to change one CJ2M's program (in Ladder, and the PLC is the slave) in order to make a list of desired variables "readable" by the master (an host computer/ SCADA) wich is using the protocol MODBUS-RTU. I only have to work on the PLC' side and i only know the name of the variables and their corresponding address.I already read the "CS/CJ Serial Communication Unit Operation Manual" but i still have some doubts:- The only way to define my slave address is done by writing a code to put the value of the address on the corresponding bits of DM area? or can i define the address using some feature of CX-Programmer?- (A CJ1W-SCU41-V1 is already implemented in the field) on the slave'side i only have to make sure the variables are allocated on the right place, according to the master's commands and modbus' addresses, right?- I read something related to the frames sended by the slave as responses for each master's command, am I supposed to write some code to do this task or it is done automatically?- Imagine the master is using the "Read coils" command, in OMRON there are 4 memory area associated to this data model "Coil" by default it is associated to CIO area, can i switch in the slave to Holding area without problem?Sorry about my english and this extensive text. Thanks.
