Problem with PID controller in FX3U
Napo_2012 posted a topic in MitsubishiHi, I have problem and hope if there is anyone who has same kind of problem, could tip me to the right direction. I have scrolled online for solution, but found nothing to solve this. Im makin heating/cooling control for radiator system. Basically temperature measurement that controls 0-10v valve. Pretty straight forward operation. Im having trouble getting PID control block to work on cpu. When in simulation mode PID works perfectly, but when i download program to FX3u CPU, PID output stays at zero. No matter what values i give to PID, manipulated output is frozen. I attach some images that will show how its running. Tried few different PID's and results are the same. So im thinking there is some trick to the cpu to start executing this block. If you have some tips, i would be gratefull :). https://ibb.co/rpqFtLN
Discrepancy TCP modbus reading
ETR Automazione srl posted a topic in Other PLCsHello, i have a curios problem in a modbus tcp reading from a client. The HC900's answer for the variable 20 (holding register 6375) is clear in the Hybrid Control Designer (the variabile is a simple counter of flow gas counter). The ammount of value is incremented every pulse from a digital input. But when i send the request from a client modbus, the value's variable is different (completely). For example the value is frozen from this morning, probably when the machine started up. The others value read directly from analog inputs are correct. Only this value elaborate from some blocks show this problem. I can't understand the cpu's logic for elaboration the exchange area memory modbus. Best regards, Ennio .

FX3U-ENET-ADP how to connect and read strings?
hewking posted a topic in Mitsubishihi All I am completely green in Mitsubishi PLC (i used to program siemens) but need kepware to connect to FX3U pls with ENET adp module. Could somebody pls help me with the very basics as kepware does not talk to the FX3U yet: What software do i need to read configuration/potentially do changes to FX3U and ENET? - is it free? How to check the port that the PLC is using - i assumed 5001 as default but it did not work- it is FX3 setting or ENET module setting? What kepware driver is best for the FX3 with ENET module? - at the moment ethernet driver seemed obvious choice to me Does ENET adp adapter can server only 1 connection at the time - is it hardware limit or something i can configure in the PLC? I will be trying to read strings from FX but how are these strings normally stored in mitsubishi FX3? - i found in the documentation that its either DSL or DSH area - is it something that has to be configured upfront or can i just use either DSL or DSH memory area? Massive thanks for any help upfront Regards
SAIA PLC - Modbus TCP truncates 32 bit value
Lupin_III posted a topic in Other PLCsHI, I'm reading values from an SBC SAIA PLC ( PCD2.M5540 model). My problem is that some values are 32 bit, while modbus return 16 bit values, of course. Registers are consecutive, so I cannot read for example 9008 and 9009 since they store 2 different information.To make it clearer I attach the PLC watch window. As you can see R9009 is a 32 bit value, but I can't require R9009 and R9010 via modbus since in R9010 register there is a different information. AS well as in R9008. Speaking with SAIA technical support, they explain me that their PLC registers are natively 32 bit, so in order to read them I need a 32bit modbus client. I cannot find anything like this, neither I can use standard modbus, since the buffer I get back is a 16 bit for each register. So 16bit for R9008, 16bit for R9009, 16 bit for R9010. What I can do?Thanks
How can I access an UR5 robot through Studio 5000?
Lucas Antonelo posted a topic in Allen Bradley / Rockwell AutomationHello, everyone! I am following this YouTube tutorial where it teaches you how to add a block of Modbus server within Studio 5000 for communication with plc ControlLogix. The video: https://youtu.be/qcF4m7rPjkw However, according to a comment from the author of the video himself in my comment I can make such a connection through a Modbus device. How do I do this within ur5 and how can i access UR5 inside Studio 5000?
Gx Simulator3 and TCP modbus
Luciano73 posted a topic in MitsubishiHi, I'm new to the Mitsubishi world, so may be anyone help me in a quick! I need to test a my client with the Mitsubishi MODBUS tcp. To do this I would like to avoid use a real plc and use the Gx Simulator3 that come with the Gx Works3. The question is: the Gx Simulator3 is capable to simulate a MODBUS tcp module? To be more specific I tried this: - created a project in Gx Works3 with a FX5U CPU. - configured the FX5U built-in ethernet module with IP address of the hosting pc (also tried 127.0.0.1 with no success). - activated and configured the MODBUS muster to the built-in ethernet module. - wrote a trivial ladder program with a 1 input and 1 coil. I can download and run the project on the Gx Simulator3 but I cannot connect to tcp port 502 that I supposed opened by the MODBUS muster functionality of the build-in ethernet module. Do anyone know if the Gx Simulator is able to simulate modbus tcp functionality? Thanks in Advance Luciano.

FX5U Modbus-TCP Server (Slave)
Dave W. posted a topic in MitsubishiHello everybody. I need a solution for Modbus-TCP server on the PLC. With the FX3U it would work with the FX3U-ENET module. The internal interface of the FX5U should actually be able to work with the library of the FX3U (FX3GModbusTCPServer_GW2_V100) or not? Because a socket connection is now possible. I would be happy about suggestions. Dave
AB ML1400 Modbus TCP/IP Communications
SRHair posted a topic in Allen Bradley / Rockwell AutomationHello, I'm new to setting up my controllers and communication between devices. We wanted to see if using Modbus TCP/IP to communicate to a load bank was the right path for us. I was able to configure my Micrologix 1400 controller Channel 1 for Modbus and set the data files. I set up a read holding register 03 message, two write single register 06 messages and one write multiple registers 16. I was able to read the data from the load bank, but I was unable to send any write commands. I didn't get any errors in the messages. I was able to send write commands through my pc to the load bank and it responded properly. So I was thinking I must of missed something in my set up in the PLC. I'm attaching the PLC Program and the command set from the manufacturer. Any help would be greatly appreciated.

how read data from modbus read_var function
saruans posted a topic in Modicon / Telemecanique / Schneider Electrichello, Somebody have suggest how need read data from slave using modbus RTU. I am using M241 PLC and read_var function. The picture you can see my PLC program. The data of slave is placed 3394 address. Then I try to read, always "READ_VAR" function get "CommError" which number is 254 that means "The detected operation error contains protocol- specific code" and "OpenError" which number is 3 that means I don't know. How need read from slave data, which modbuss adress is 3394?

Omron Beckhoff EtherCAT Communication
Hadi.B posted a topic in NJ Series / Sysmac StudioHi, I have a problem with Omron PLC and Beckhoff IO. The IO just disconnects in a few minutes and comes back! I received different errors: Link off error, Illegal slave disconnection, process data reception timeout. When I also check "Display Diagnosis/Statistics information" I see errors on all ports A and B of all nodes. I have called and talked to both Beckhoff and Omron. I have two NX1 and one NJ101 to test. And I have three EP2318-0001. I have the same problem with all the PLCs and EP boxes. It does not matter if I have one, two, or three nodes. I have tried different revisions of the EP2xxx from the XML file, different settings for the slave, different task periods, and the error still is persisting.
MX2 Modbus doubt
Robror posted a topic in OmronHi there! I'm programming a CP1L-E CPU to control 3 3G3MX2 inverters via Modbus. It got some things right, like the INV002_Refresh_X31 block and its parameters. The thing is, I also want to read some parameters from the inverter using the INV206_ReadParameter block. My doubt is, do I need to be careful so both blocks don't execute at the same time and use the serial port at the same time? Is it better to use one INV206_ReadParameter block for each parameter I want to read? Thanks in advance!
GOT2000 as MODBUS TCP slave
Szabo Zoltan posted a topic in MitsubishiI have this setup: FX3G CPU connected to GT2103 through RS422 (CH1). GT2103's ethernet port connected to LAN and set up as modbus TCP slave (CH2). I want to read/write PLC word devices using a modbus TCP client, from a PC. The HMI is acting as a gateway between PLC and PC. I used the Device Data Transfer function to send PLC's D register values to GT's internal GD registers. D0....D9 ==> GD0....GD9 After some tries, I get valid response from the modbus slave. Reading the holding registers 0....9 (40001....40009), I get only zero values. Those registers can be written back with different values, correctly. I'm sure I didn't understand correctly the modbus address mapping to GT's internal memory. Can anybody help me? Thank you.

HARSHAL posted a topic in CX-ProgrammerHello everyone I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure. Thank you
connecting Modbus cp1L-M to Beckhoff bk7300
enric posted a topic in CX-ProgrammerHello friends, I am an Omron PLC user, but have never used modbus before. I have to connect an Omron CP1L-m to Beckhoff bk7300 via modbus serial gateway. 2-wire RS-485 connection (CP1W-CIF11). I have seen an easy to use Modbus RTU master for CP1L CP1H CJ1 CJ2 CS1 but the examples are not for dual port CP1L-m. If I change the PLC model "CP1HCP1LModbusDualPort" to "CP1L-M", the compiler tells me a lot of warnings about variable types. Is Modbus RTU Master easy to use for CP1L CP1H CJ1 CJ2 CS1 compatible with CP1L-M dual port (port 2)? I have tried to use it but it didn't work, error 02, illegal function code. Somebody could help me? Thank you Enric
