  1. 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!
  2. CIF11 Modbus Slave

    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

  5. Modbus TCP with CP1H and CP1L from PM

    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

  8. RJ71C24

    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
  9. 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.
  10. 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.

  13. 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  
  14. Connect PLC to Kepserver

    I have Delta 12SA2 PLC it has RS232 port and I have connected it to kepserver (by Modbus serial) and then factory IO Now my problem is that when I connect my PLC to kepserver the RS232 port becomes busy with the kepserver and not available in the ISPSoft and therefore I could not demonstrate factory io and my logic in run mode in the isp soft together like you do in your videos. My PLC don't have ethernet port but is there an option in kepserver or any way by which i can use the same serial port of the PLC in isp soft run mode and kepserver+factory io together so that I can simultaneously show the logic running in isp soft and application working in factory io to my students. I googled a lot and found some softwares which make virtual serial ports for a given serial port but they don't work and soon hang Please help me I am in a great need of it. Thanks in advance.
  15. MODBUS-RTU slave

    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.
  16. Hi all,           Good morning. The PLC I'm currently working is Mitsubishi FX3G. I want to send username (in string format) from Weintek HMI to this PLC. But the string format is not supported in FX3G. But I can get the data into PLC in HEX format. For each string, two units of HEX places are used. For eg., T = 54 (Base 16) TO = 544f (Base 16) TOM = 544f4d  (Base 16) TOMY = 544f4d59 (Base 16) In FX3G, the data range of Double Word HEX value is 0 to FFFFFFFF (i.e. upto 8 units). Please refer the image attached. But for my application, I need to have username up to 10 string values. So the HEX data units required are 20 units i.e. 0 to FFFFFFFFFFFFFFFFFFFF. Can anyone suggest how to get it please?
  17. Hi all,               I am working with FX-3G PLC and it is communicating with a Weintek HMI. I am feeding a data in HMI in float format through a D register. But it is showing some other value in PLC. I don't know what is needed to done to extract the same float value into FX3G plc. So the basic question is how to store that float value in any of the registers in FX-3G plc? Requesting your support please.
  18. Modbus TCP/IP iQ-R series

    Hi, I have R04CPU (iQ-R series) on one side and on the other side is QJ71MT91 (modbus tcp/ip module). Is it possible to make communication between them (QJ71MT91 is master and R04CPU is slave)? iQ-R series doesn't have Modbus TCP/IP module, but is it possible to set modbus tcp/ip on built-in ethernet port of R04CPU, and how? Best regards Luka

  22. Is it possible to use FX3U-485ADP-MB as a serial port to send and receive user defined string/data to and from a computer? I have a FX3U-32M PLC and two FX3U-485ADP-MB adapters. I have been using PLC with one adapter as Modbus Master. Now i want to use both adapters, where one will be Modbus Master as usual and the other I want to use to send and receive data to and from computer terminal (Example - Realterm). I have a third party 232/485 converter which works really well. Lets me just describe my requirement straight forward. I want to display process parameters on a windows computer based user interface (UI) and also set some variables in PLC from the same UI. The UI has access to serial ports of computer.
