Hello, I'm relatively new to PLC programming. I am trying to creat a ramp down function, I have an example here of what I am using. I can get the function to work, the issue is that the OUT (variable3) value is being held by the FB so after I use it once it no longer works. In this example i set variable3 to 100 and the rest is as seen, over the course of a minute it ramped down to 10 (as desired). But when I deenergize TEST_START, set variable3 back to 100, and then re-energize TEST_START it immediately...

Hello, I am working on a project with a Beijer Nexto Xpress. I have done this a few times with no issues but for some reason this time when creating a Symbol Configuration the ARTI .xml file is not being created in the Project Folder. However when manually putting the ARTI tags in the HMI program they are connected and work. So I am just not getting the file to import all the tags. I can do it manually which is fine but no matter where the project folder is saved this occurs. Anyone experienced this?...

Thanks! I'm trying to sort out how to actually map those as under Modbus Slave Init I can only change the Register offset of the write data addresses (function codes 5, 6, 15, 16). I've done this exact setup with other PLC's but this interface is messing with me.

Sorry this attatchment didn't add for some reason

Hello, I am having a little bit of trouble getting my serial modbus setup. I am using a GN9373 as the master and a M9273 as the slave connected via RS485. I keep getting an "Illegal Data Address" Error as seen in the screenshots. I'm starting with a simple switch and light program to try and get it going. I have tried programming these variables as bits in holding/input registers as well as Coils/discrete inputs. I have also switched the Master Bus Cycle Task to MainTask and always update slave variables....

Thanks! I'll give that a go.

Hello, I am working in Codesys 3.5 SP17 Patch 3. When I try to login to the PLC I get the two errors seen in the screenshot. I have tried changing the version of CMPTLS, CMPTLSImplementation, and SysSocket2 in the placeholders tab of the Library Manager. I have also "Repaired" Codesys via the Codesys installer however have been unsuccessful so far. Has anyone run into this before? Thanks!

Hi, I'm setting up a modbus system in BCS tools and iX Developer. The slave is a Nexto XP340 and the master an iX TB12 SC. I have successfully linked the two and flipping my switches shows changes in my BCS ladder logic, but I can't seem to figure out the addressing for my bulbs (read inputs). It is supposed to be switch 1 lights up bulb 5, 2 lights 4, etc... I've attached two screenshots. Sorry if the answer is obvious I'm quite new! Also: iX settings are Ethernet TCP/IP, little-endian, Decimal...

Hello, I'm fairly new to programming and PLC's. I am working on this project in BCS Tools and iX developer so hopefully this is the right place. I've attatched a screenshot of a section of my BCS tools project. I am attempting to be able to turn a light bulb on and off with a switch in iX. I believe I am running into issues on the BCS Tools side. I am able to login and download to both the HMI and controller. I cant find an option to add the HMI (Master) into BCS tools so perhaps that is my issue?...
