Hi Wal, Port502 looks to be the setup for Modbus TCP.  This would be the protocol that I would use since this is a Modicon product. (Schneider Electric) Here are some links that help to describe the modbus protocol: https://www.rtaautomation.com/technologies/modbus-tcpip/ http://www.simplymodbus.ca/TCP.htm Ethernet IP (EIP) would be my next choice. Regards, Garry

I have not used your setup before but... CommHead - Communication Heading Currently it looks like you are showing the Security tab. Move to the IPConf (IP Configuration) tab to set the configuration. The following links may help you out. http://www.plctalk.net/qanda/showthread.php?t=92751 http://www.plctalk.net/qanda/showthread.php?t=82781   Regards, Garry

The NX1P2 PLC manuals indicate that the serial port must use FINS commands. The program frame would be similar to the C Mode but the actual commands will be different. See the following manual. https://www.myomron.com/downloads/1.Manuals/PLCs/CPUs/W342-E1-14%20CS_CJ_CP+HostLink%20FINS%20ReferenceManual.pdf Regards. Garry

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 Linus, The Omron NX1P2 PLC can use the same method to communicate through the serial interface. http://www.ia.omron.com/products/family/3650/specification.html The serial ports will support the following protocols: Supported protocol Host link, Modbus-RTU master, and no-protocol Regards, Garry

Same error and solution was the same. The problem was fixed by just unplugging the power and let it sit for a longer time. Regards, Garry

NX-EC0132 http://www.ia.omron.com/products/family/3190/specification.html RS422 (TTL) RS422 (TTL) circuits provide a constant 5 V signal level that is not dependent on the supply voltage. Two supply voltage ranges can be selected: From 4.75 to 5.5 VDC (can be used to replace open collector output drivers) or from 8 to 30 VDC. Using differential signals the output fully complies to the RS422 standard. https://www.posital.com/en/products/communication-interface/incremental/incremental-encoders.php   The above information may help you out.

Not much information on this product. I would contact your distributor or manufacturer for the serial port pinout. Regards, Garry

https://www.fa.omron.com.cn/data_pdf/mnu/w397-e1-08_cj1w-nc.pdf?id=31 I would go to section 10 of the above manual and work through an example.  Regards, Garry

The CP1E can use both Omron Host Link and Omron FINS Serial. This is for a serial communication (RS232 or RS422/RS485). If you have an Ethernet connection then select the Omron FINS Ethernet. (RJ45 - Separate module required. See link below.) http://www.ia.omron.com/products/family/2064/lineup.html Hope this helps you out. Regards, Garry

Thanks for the update. Garry

In the PLC Attributes [TEXT] under Data Type  is there an option for ASCII instead of Unicode? Unicode takes up more bits than the traditional 8 bit ASCII characters.  Just a thought. Regards, Garry

http://industrial.omron.com.br/uploads/arquivos/Datasheet-CQM1H.pdf Yes fins communication will work for the CQM1H. Under network type select controller link.  Regards, Garry

How about using the copy command and transfer the DM area word to the HR area word.  In the HR you will have access to bits. H000.00 Arrange the HR bits on the individual output condition. Example: D100 move to H100 (Value 110) Each of the digits will have 4 bits, 12 bits on the run for the 3 digits. 12 bit conditions - Output 0.00 Just a thought. Regards, Garry

The first is establishing communication to the Omron PLC. The second is using AdvancedHMI to get data out of the Omron PLC. The entire Omron CP1H series can be found at the following address: http://accautomation.ca/programming/plc-basics/ Look for Omron CP1H Series. Regards, Garry

I would use the raw values from counter 0 and 1. Read the values, compare and reset at an update frequency that will work in your application. Regards, Garry
