Thank you Chelton for the clarification. I'm using implicit connection. My nodes uses both input and outputs. They are mainly 14 servo drives, 17 SMC valve banks, 4 cognex vision camera and 4 remote IO modules. I also plan to have a data link connection with another CJ2 PLC for some data sharing. [ The other PLC had more or less similar node count on its own network]. When having a data link connection, will that combine the node count on a single module?

Hi, How many does does CJ1W-EIP21 support in Ethernet IP connection. A bit confused when reading the spec from the manual. It says - No of connections - 256 Class 3 (connected) - No of connections - 128 UCMM (unconnected)  - Number of clients that can communicate at one time: 32 max. Number of servers that can communicate at one time: 32 max. I have more then around 40 nodes to be connected thru this module to a CJ2M PLC. What are my options? Thank you

Hi Chelton, For the PLC with nodes lower than 63 I am getting the results in the default CIO area now. But for the PLC with nodes higher than 63, I configured using the user status settings and now I'm getting the data on both systems.  Thank You

Chelton, Thank you for the reply. How do I identify the node number of each device. Does goes by the last octet of the IP address of each unit. My Network card [Unit number 3] on the PLC is using 192.168.1.10, HMI is .11, followed by devices start from .20 onwards. I was looking at the Network configurator to see any node number reference, couldn't find it. My total node count on each PLC is using less than 20 nodes in total. highest last octet number on one PLC is 43 and the other one is 89.  So based the notes, CIO 1591.00 ~ 1594.15 and 1596.00 ~ 1599.15 I should see some feedback when it is running normally, right. I will look out for it on Monday. From the manual I see n+16 onwards is the "registered target node" and n+20 onwards are the "normal target node". What is the meaning of registered/normal? Is it those nodes registered in Network configurator and those that are found on the network? Thank you very much.

Chelton, I was looking thru the manual as you stated, As usual Omron manuals are difficult to crack. I'll continue to grind it ........ Thank you

Hi,   I am using CJ2 CPU 33, with a CJ1W-EIP21 connecting around 15 devices on an Ethernet IP network, [ some remote IO, servo drives and SMC valve banks]. How do I monitor whether these devices are connected and active in the network. First time doing this in an Omron PLC. Thank You Regards

If both of them are connected thru ethernet IP, then data link is an option. https://www.myomron.com/index.php?action=kb&article=1416  

Good thought, I'll try that out, thank you

It's a new equipment we are building. So everything is new

What RS Linx displays is just a feedback of what it is detecting when you go online. A red cross comes on top of it, when undetected. So deleting it do no harm. When your device is back online, it reappears. 

My PLC scan time display around 3.45ms

I hope you have selected either Address or All [Strings] in the search dialog box 

Hi, On my ongoing project I'm facing slow editing/assembling of rungs when ever I have to make changes online. It was OK earlier, but when the program steps have increased, I face this issue. I used to write a lot of comments on instructions, rung comment etc. Not sure that's the cause, but I doubt so. It's CJ2M CPU 33. I'm connecting using USB. The I/O table consists of a CJ1W-ETN, with 3xID262, 1xOD262. The Ethernet IP had around 34 devices, [Remote I/O, servo & SMC valve banks]. The line also had 4 Proface HMI on Ethernet.. Attached is my memory view. Googled about it, unable to find any clue. Does anyone come across, how to fix this. My CX-Programmer version is 9.8 Thank You

Thankyou IO_Rack and Bob. Your solution works just fine. Never thought a simple plain division can solve this.   Thank You Best Regards _____________

No, I guess no option for that. I'm using an Elcis encoder. I was trying to do it in CX-Programmer.   Regards ________
