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.
KINCO PLC as MODBUS RTU slave
Francisco1998 posted a topic in Other PLCsHello to everyone. I hope you are doing well. I'm trying to establish a communication between my PC and my KINCO PLC. The manual states it supports MODBUS RTU protocol, so I downloaded two different Modbus Master simulator I found out: Multiway from OMRON and qModMaster. None of them seem to work properly. I attached some pictures of the messages I get. https://ibb.co/f1mCSNt Multiway message https://ibb.co/bP5cX1t qModMaster message I include the configuration of the communication parameters. https://ibb.co/nMty8D9 PLC parameters https://ibb.co/6RTqVfC Multiway parameters https://ibb.co/N1XTccd qModMaster parameters According to the manual, in order to play the role of Modbus master with the PLC it's necessary to configure some instruction blocks (I'm programming in ladder). However, I could not find any block to configure as Modbus slave. I don't know what else I can do. I'm in trouble with this task. Am I making some mistake? Thanks for your attention. Kind regards!
Profibus communication between DELTA PLC and Siemens
Ylber posted a topic in Other PLCsHello guys, I have an application with a Delta PLC (slave), Load cell module and Delta HMI. The problem is that the Delta PLC has to report to the already existing platform of Siemens S7 PLC (Master) with Profibus. The Master (Siemens) writes and reads data from the Delta PLC. The question is, how can I set up the Profibus communication? Are there any documentations about the Memory Mapping, configuration etc. There are some modules for Profibus Slave from Delta but I cannot find any references or anything. Thanks in advance.
Master Doesn't see Holding Register
Tom_ posted a topic in SiemensDear Engineerds, My Master (non siemens) doesn't see the Holding Registers of the Slave (S7-1200) plc. However the Q coils are fine and all Diagnostics don't show errors. The Hardware: S7-1200 – CPU 1215C CM PtP – CB1241 RS485 (6ES7 241-1CH30-1XB0) - Half Duplex RS584 Firmware: Modbus_Comm_Load (V3.1) Modbus_Slave (V4.0) I've tried with various DB, UDTs and manipulating HR_Start_offset parameter with no success. Could you advise what am I possibly missing? Modbus_Comm_Load_DB_Snapshot.xlsx Modbus_Slave_DB_Snapshot.xlsx

CIF11 Modbus Slave
cyrus posted a topic in CX-ProgrammerHi 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
Two FX3U-485ADP-MB One Modbus Master and Other as General Purpose Serial Port
ritz2610 posted a topic in MitsubishiIs 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.
ML1400: Manipulate output through modbus/tcp
MikosMotta posted a topic in Allen Bradley / Rockwell AutomationHello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob.

Mitsubishi iQ-R Series
CementMatt posted a topic in MitsubishiHi Has anyone got any real life experience with the new Mitsubishi iQ-R series? I have been assigned a major capital project to replace our old ageing DCS system. Our current PLC backbone is about 40x Q2ASHCPU, 10x Q06UDEHCPU and about 2xA2SCPU all linked up via Melsecnet/10 network with communication links into the DCS system via Modbus RTU utilising the QJ71MB91 modbus card. Due to the nature of my companies process and the limitations on plant downtime it is estimated this project could take up to 5 years to complete, with this in mind I am wanting to install a system that will not be obsolete (or unsupported) in a few years, hence, I am very interested in the new iQ-R series with it being Mitsubishi's latest and greatest. However, recent communications with my local Mitsi rep is not filling me with confidence that the iQ-R series is not as well supported/developed as the Q series. A major requirement during the development stages of this project is the new ability of the new processors to be able to talk to the old DCS up until a point where the DCS nodes will be completed removed and replaced with a modern SCADA package. Hence, the requirement of a Modbus Slave card for the iQ-R (i.e. a QJ71MB91 equivalent) which I am told is in development, but has no fixed timescales. Previous experience with Mitsubishi developments of cards is normally years not months. Any information anyone can provide on their experience of the iQ-R series would be greatly appreciated and if anyone knows if a Modbus Slave card is in development that would be useful. I realise i could utilise the Q series extension rack with a iQ-R processor but this is not the route i want to go down. Thanks for any help and apologises for the war and peace. Cheers Matt
MZohaib92 posted a topic in Other PLCsHello guys, I am using Fatek PLC's to communicate with each other as a Master & Slave through zigbee which is connected through RS485. And I succeed. But the issue is that I have to communicate each other at a distance of about 2km where zigbee out of range to each other. I am bit confused here; 1) whether I use RF booster? Does it work? 2) Should I introduce extra PLC as a repeater between master slave? But this(extra added) PLC repeater also become as a master(Master Repeater).or any idea? Most important I can using Fatek Protocol or Modbus RTU or Modbus ASCII prootcol.

Master-Slave master side SW architecture with Custom RS422 full duplex protocol
GuyB posted a topic in Other PLCsHey Guys,i'm working on implementing the master side of a custom serial master-slave protocol between a B&R PLC and an electronic card.As part of the data i'm sending and receiving is used to close various loops(e.g. cascaded temperature control where the temperature sensors and actuators are connected to the electronic card) , but other data is not as usefull (e.g. various data used for display or at specific times), i believe i will also need to implement some sort of priority mechanism.my first question is - based on your experience - how would the general master side SW architecture look like? (for example - the send side of mine is comprised of 3 tasks all running under the same cycle - lower level task in charge of opening the port, sending the data etc, a mid level task in charge of creating the packet based on command from upper level, giving commands to lower level and using status from it to continue and finally - an upper level task in charge of deciding which messages to send).my second question is - how would you implement the priority mechanism?thanks
NB Display MASTER SLAVE
manowar posted a topic in Other Omron SoftwareHello. I have a question regarding NB series display. The comunication is made through RS232 / RS485 comunication. I would like to use NB display as MODBUS MASTER and SLAVE aplication. - Display would work as MADBUS-MOSTER to talk to plc controllers. (Working through COM2 - RS485) - Secondly, Display would work as MODBUS-SLAVE to talk with (SCADA). (Working – Registers LW, LB)) What I have trouble with, is: - I would like to change variable in the PLC - for example : Regime_PUMP (address: 0x0001). - Regime_PUMP variable should be settable from all three devices PLC <-> DISPLAY <-> SCADA So: - If I change Regime_PUMP through PLC it should refresh also on DISPLAY and SCADA. - If I change Regime_PUMP through DISPLAY it should refresh also on PLC and SCADA. - If I change Regime_PUMP through SCADA it should refresh also on DISPLAY and PLC. Does anybody have an example for NB series of display to do this? Best regards.
CP1E MODBUS Maximum Slave
innoaloe posted a topic in OmronHello everyone, so I noticed in Omron's CP1E manual, there are no certain info on maximum number of Modbus Slaves that can be attached, however the PLC itself able to connect to slave number 1 - 247 I have read from common MODBUS specs, that 32 slaves are the limit for most MODBUS connections. However there are also statements that with proper design (1/8 transceivers) that we can extend number of connected slaves to 256. Anyone have experience or info about this with Omron PLC? Thanks in advance

possible to connect to Ethernet/IP slave from AB Micro820 ?
peternn posted a topic in Allen Bradley / Rockwell AutomationHi, I have AB Micro820 PLC (2080-LC20-20QBB) which, acc. to the specs, can be both Ethernet/IP master and slave. I need it to be a master(scanner) and communicate with a KEYENCE DL-EP1 module, which is Ethernet/IP slave(adapter), but don't see any way to make that happen. How do you declare/configure Ethernet/IP slaves in Connected Components Workbench and how do you add slaves to your CCW project? I have an EDS file for the slave, but what to do with it? I imported it (have no idea where) with the EDS hardware installation tool which reported all was OK, but do not see the slave anywhere in the CCW. I only see in the Device Toolbox > Discover, but the only available option there is to remove it :) Thanks for any suggestions. Peter
