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.

Beginnerproblems FX2N-48MR, FX2N-232IF Read/Write over Serial
feuertaenzer posted a topic in Mitsubishi
Hello At first - sorry for my bad english. I have a FX2N-48MR with a FX2N-232IF and i only want to watch the X and set the Y over RS232 with a Crestron Contolunit. I use GX Developer 8 on a XP Laptop and figure slowly out how it works. I read the manuals i found, managed to send from the PLC to the Serial Program on my Laptop (Program named HTerm) But i do not figured out the sending. Can you give me some hint? Greetings FT -
Hi! I would like to know how I could send information throw serial RS232 communication. I mean, I have CJ1M-CPU11 connected with ID232 and OC201 modules, and I have an optic sensor (digital input). When the sensor turn on, I would like to be able to read the information (on/off) with an application like Putty (I have the PLC connected by RS232) to develop an application and show the information on another framework. I don't know if I have explained very well. Thank you!

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

Greetings, My application is utilizing two Omron CP1L PLCs connected through an RS232 serial link to achieve PC Link. We're essentially using this setup to message data between the two PLCs. With a hard-wired link, it works great. I can force bits in the master PLC, and see them in the slave PLC. However our application requires this link to be wireless. We got our hands on two SENA Parani SD1000 units. I've worked with these units previously to connect a serial scanner to a Rockwell PLC quite successfully. After reading through datasheets, we figured out the pin-out from Serial Comms unit fitted to the CP1Ls wasn't quite standard. So we adapted our own cables to re-route VCC and SG appropriately. So with a hard-wired link, this setup works, and the comms units on the PLCs have a nice solid lit up comms light. But with the wireless parani connection, the comms light lights up, but it is very dull compared to the wired link, and we get no data transfer. I've verified to the best of my understanding that the comm settings all match, at 9600 Baud, 8 data bits, 1 stop bit, and Even parity. Just curious if anyone has any suggestions to get this working, or if there are any settings that I might have missed that make PC Link a unique form of RS232 that these parani units can't handle? I've identified online alternative units known as the Promi SD205-OA, which has a pin-out to match the OMRON CP1L PLCs. As far as I can tell though, the units themselves function the same as the Parani SD1000 besides this pin out. Anyone know differently? Presently the serial connections made are Tx -> Rx, Rx -> Tx, Vcc -> Vcc, and SG -> SG. Would I require anymore connections? Our wired link seems to work just fine with just those connections. Any help would be greatly Appreciated!!

Hi, I have encoder and count pulses in mode "Differential Phase Input" - Linear mode Every one turn I have Z-phase reset and counter starts from 0 I set some target value comparison table from D1000 for @CTBL #0000 #0000 D1000 and it works just one to reach target value After PLC start and HSC reach target value for Interrupt 01 I get subroutine working, but even I reset HSC using Z-phase signal and PV goes to 0 still interrupt is activated. I would like to start and stop interrupt during one turn of encoder and make it every one turn Thanks for clue

Hi guys, I was programming my CP1L-E over ethernet with no issues at all. I did get an error when uploading my program regarding cycle time, so I went into PLC->Settings->Timings and changed both values to maximum (4000*10ms watch cycle time and 32000ms constant cycle time). Once I restarted the plc it just wouldn't connect. I've tried option cards CP1W-DAM01, CP1W-CIF41, CP1W-EIP21 and i just cannot get comms with the PLC. I can see the CP1W-EIP21 card on my computer, however,, in its own IP address. From what ive figured, the plc is getting stuck somewhere in its boot cycle as I am unable to ping it either. The POWER and RUN lights are both green, and the LNK/ACT light flashes when i connect an ethernet cable to the inbuilt ethernet port. Any help is appreciated, thank you! Any way to factory reset the whole plc or even just the settings? I've disconnected the battery for 30 minutes before plugging it back in aswell but that did not help me.

Overcoming 'STRING type or an Input Output variable is not supported'
viman posted a topic in CX-Programmer
I get the input of an encoder and do operations based on that, for at least twenty object 'slots' at once. Program is on ladder since client needs to be able to modify it at will, but I'm using structured text functions to handle all the messy operations, since every object has properties and data, and up to twenty can be running in real time. This is a CP1L. Instead of instancing those function blocks twenty times each, I keep a single instance of them one running all the time, and output TRUE when one of those objects raises a valid comparison. In essence those FBs compare each objects' relative position to the encoder against defined points. The picture is an example of the functionality I'm needing. When one object completes the FB task, one of its flags turns ON so that it can't be used anymore. The issue is that without an input/output ST variable, this flag stays ON no matter what, and I need to reset it from outside so the cycle can begin again. The inner FB bit linked to this output stays ON since nothing inside of it makes it change. That's why I need an input/output variable. In the picture the timer would reset the bit - until the FB turns it on again - but I can't do this in this controller. Is there an elegant way to make this work? I know I could use the rising edge of the output to turn some other bit ON but that's the kind of thing I want to avoid. -
ok running into a issue here, so we were able to communicate with the processor to download a program. transfer went fine. upon cycling power, we can no longer connect to processor. we used LM90 for the software. i've tried removing the battery and shorting out the "mem clear" points on the board, however we can no longer communicate with the CPU. we have a POWER and OK light solid on the power supply. kinda stumped here if anyone has any insight.

Hi guys, I am trying to make a controller for an oven using MODBUS with a CP1L and an NB screen. My oven program will have 10 stages in one baking cycle, and the parameters for each stage can be modified individually (temperature, blower speed and time). I have set my number input in the NB screen to be a unsigned int of 2 integers and 2 decimals, and it writes to H4 in plc H memory. I move this value from H4 to W4 in the PLC, and input W4 into a timer (T0000). I have tried data manipulation and still have no success in getting this to work properly. My CP1L timer is set to BCD mode, as I am using premade MODBUS function blocks which are programmed with timers in BCD mode. Does anyone have any pointers regarding this? In the screenshot provided, the number i inputed in the HMI was 60.00.

Two FX3U-485ADP-MB One Modbus Master and Other as General Purpose Serial Port
ritz2610 posted a topic in Mitsubishi
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. -

Hello every one. I have three FX3U plc needed to be communicate over a wireless network. I'm using serial adapter FX3U-485ADP. I got E-byte data trans reciver E-30 for wireless communication. Now need help to setup the whole thing. Previously the PLC's serial connectors were connected through a flexible bus but when the platforms are running fast there is interruption in the communication. So we want those PLC's to be connected over wifi. Thanks in Advance

Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form. http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

Hi, I have a self-bought usb-serial cable converter for CP1E. Currently can't connect to my PLC using PC. CX-One says "Failed to the PLC". I am supposedly to use "SYSMAC WAY" as my Network Type in PLC settings? EDIT: The CPU type is N30 I've checked the following settings: 1) COM number is correct ( as checked from windows Device Manager side) 2) Cable driver is installed, there is no "unknown" driver in my windows Device Manager 3) My RS232C LED in PLC is not lighted up. Any other suggestions to check settings ive missed out would help, other than buying a new cable for the moment. Regards, Summerstone

I need to add 3 encoders to my project. Currently my PLC Inputs are full. I am using high speed counters 0.00 and 0.001 to monitor a motor RPM with an encoder. I now wish to add 3 encoders to monitor position of (3) other linear axis controlled by stand alone (Zeta 6104) stepper drives. I have 3 open outputs on this PLC but all inputs are used. What are my hardware options to add additional encoders to allow me to track and correct the 3 additional axis. My first thought was to add another CP1L and use PLC1 0.00, 001 for ENC1, PLC1 0.002, 0.003 for ENC2, PLC2 0.00, 001 for ENC3, PLC2 0.002, 0.003 for ENC4. I thought this would allow me to use additional I/O from the second PLC but I am not sure if this is even possible. Is it possible to connect 2 PLCs this way? I will need additional I/O to send to these stepper drives to make the corrections. Do I need to add an expansion unit to the existing PLC and 2 additional high speed counter modules? The encoders are all Omron E6C2-CWZ6C. I would appreciate any advise on options to add these encoders and help point me in the right direction. Thanks in advance to any help.

Hello, PLC: NX1P Comm module: NX-CIF105 I am running a serial (RS485) network to control several motors. As a trigger for to read the serial port I am using the ( Ch1 Receive Data Exist) bit, which is an internal bit that's ideally should be energized when there's data in the Receive buffer. However, this bit isn't reliable at all. I am reaching out today to figure out if there's another way to trigger the receive command ( preferably without a delay) thank you all Cheers!
