Need help read data from omron CP1L using modbus tcp
gclshortt replied to underwater's topic in Omron
It sounds like a timing issue. I would slow down the time between the polling of the PLCs to see if the errors go away. Just a thought, Regards, Garry -

You should be able to clear the message using the PRO27. I would put the switch in PRGM mode and hit CLR MON CLR on the PRO27. You can use the arrow key to scroll down and see your program. This unit would be similar to the C20H. https://www.fa.omron.com.cn/data_pdf/mnu/w246-e1-01_c20hb.pdf?id=3051 The program can be entered through the PRO27. Regards, Garry

RS232 is usually a 1:1 communication. This means that you have one master asking questions of the slave, who can only answer the question. RS422 / RS485 are usually a 1:N communication. This means that you have one master asking questions to several slaves that can answer only when they are addressed. http://www.rfwireless-world.com/Terminology/difference-between-RS232-RS422-and-RS485.html The above link may also help you out with these media types.

The Horner PLC is an All In One controller. PLC, HMI, Logging. It has several different options for communications. http://accautomation.ca/series/horner-xl4-series/ Here is an article on the differences between a PLC and Computer control. https://www.controleng.com/single-article/six-key-differences-between-plcs-and-computers/aead1d8b9cba5755f8f24dbc9a031e52.html Regards, Garry

I do not think that you will find a C-mode hostlink library for the NJ/NX. Here is the manual that gives a good overview of both protocols and reasons for each one. https://www.myomron.com/downloads/1.Manuals/PLCs/CPUs/W342-E1-14%20CS_CJ_CP+HostLink%20FINS%20ReferenceManual.pdf " C-mode commands are specialized Host Link communications commands. They are issued by a host computer and sent to a CPU Unit. The devices that can be connected for serial communications are the CPU Unit, a Serial Communications Unit, and a Serial Communications Board." " FINS commands are message service communications commands. They do not depend on a particular transmission path. They can be used for communications on various networks (Controller Link, Ethernet, etc.) and for serial communications (Host Link). They can be issued from a CPU Unit, Special I/O Unit, or host computer, and they can also be sent to any of these. The specific commands that can be sent depend on the destination. " I'm not sure of your application, but what about using AdvancedHMI for communication. The Omron drivers are already in this free product. https://sourceforge.net/projects/advancedhmi/ Just a thought. Regards, Garry

https://www.eurotherm.com/index.php?route=product/download/get&download_id=137 7 MODBUS TCP SLAVE COMMS 7.2.1 Function Codes - MODBUS function codes 3, 4, 6, 8 and 16, defined in Figure 160, are supported and are fully described in Section 7.3, below. Function codes 5, and 2 are not supported. What is the actual information you are writing to the controller? If it is more than 16 bits long then use the function code 16. Regards, Garry

High speed counters ML1100
gclshortt replied to GL3NN's topic in Allen Bradley / Rockwell Automation
http://www.plctalk.net/qanda/showthread.php?t=26805 There is only one HSC on the ML 1100. ML 1500 has two. The above thread points this out. Regards, Garry -
Are you using Function code 16 - Write multiple output registers? Sometimes if a parameter uses 32 bits you must use write using function code 16. Is this the same type of data that you are reading? Regards, Garry

http://www.edata.omron.com.au/eData/PLCs/CQM/W228-E1-08.pdf As Michael has said, you need the PLC in monitor mode. This is done in the CQM1 in the setup area. 1-1-2 CQM1 PC Setup Settings - In the above manual will show that the number #0201 in DM6000 will ensure that the PLC will always be in monitor mode.

This link will take you to sample programs and explanations of the Modbus RTU protocol by Omron. https://www.myomron.com/index.php?action=kb&article=1243 It sounds like you are using a sample program for a Modbus RTU Master, so all of the communications will be initiated by the PLC. This means that you need to have the arduino set up to be a Modbus RTU Slave. I would start to try to communicate to the arduino using the PC modbus master software to see if you can get communications. Here are a couple of links explaining Modbus: https://www.rtaautomation.com/technologies/modbus-rtu/ http://www.simplymodbus.ca/FAQ.htm Omron Modbus Map for Slaves http://www.tri-plc.com/appnotes/modbus-map.pdf The other way to get the information is to use the serial host link communication method. This will utilize the RS232 port on the PLC. http://etowyzagagexod.tk/547903db83.html https://forum.arduino.cc/index.php?topic=147526.0 Regards, Garry
