Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Post by toby on Ethernet/IP communication with Omron NX1P2 ^{CODESYS Forge talk (Post)}
Hey guys, I'm very much a noob with networking, it's my achillies heel, and this is my first networking project using Ethernet/IP. Any help offered is GREATLY appreciated. I'm trying to network a Codesys Project with an Omron NX1P2 PLC. I'm using EIP due to hardware restrains. I've added the fieldbus, EIP scanner (as the master), and made a Network Variable List. On the Sysmac Studio end, I've made the variables and set them to network inputs/outputs, registered them in EIP settings, but when I try to set the target device (the Codesys project), I suspect I need to import an EDS file for the EIP mapping. Back in the Codesys project, I'm not sure how to: - Make an EDS file to share with Sysmac Studio - How to link the target device (Omron PLC) to the EIP fieldbus - How to map the inputs from the Omron PLC. Im sorry for my very open request for help, i'm kind of lost looking through the various forums/video/tutorials as many of them dont match what im trying to do. Any help, or sample programs would be so so greatly appreciated. If you need any further clarifications, please feel free to ask. Thanks in advance, Toby
