Post by idalu on Profinet PN_Controller Issue, Network Adapter ^{CODESYS Forge talk (Post)}
i have a problem with Profinet on my project. I'm using Codesys RTE 3.5.19.50. When i download program to controller the ethernet is ok, PN_Controller is ok but every device i'm trying to connect is red with error "DCP no RealStationName". When i'm trying to Scan for Devices on PN_Controller there are no devices found. I have installed Codesys driver CmpEt1000Drv to my network adapter (i'm sure it is right intel pro 1000 model). I have noticed that when i installed codesys driver i'm no longer able to ping this network adapter (i can ping it when intel driver is installed). On my previous projects with runetimes i can ping it even with codesys driver installed. I have also tried to do downgrade of everything to version 3.5.19.20 and it not helped.

So it's currently mapped to an array of BYTES? Can you create a UNION? TYPE sBytesString : UNION AsBytes: ARRAY[0..127] OF BYTE; AsString: STRING(128); END_UNION END_TYPE Map it to the bytes, read it in the STRING!

Thanks, that's what I thought initially. The point is that I can't select a String type variable. See the attached image

du musst die IO's auf Variablen mappen die dan auch in den Pou's verwenden. CODESYS aktualisiert IO's die auch verwendet werden.

Most likely your IP address is set to 172.... because you use a VPN connection to your device. Probably best to use the other Ethernet interface for your modbus communication.

Post by pascaljt on Function block for Ethernet/IP ^{CODESYS Forge talk (Post)}
Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)

Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

did you try setup two eth ? on ethO you set ip to communicate with pc, example 192.168.0.1 on eth1 ip to communicate with weidmuler I/O, example 192.168.100.1 note : ip need the same of ip setup under system setting of hmi.

Post by dekelec on Codesys 2.3 & Peak PCAN ^{CODESYS Forge talk (Post)}
I use Peak USB adapter daily to download from CoDeSys 2.3 and 3.5 to IFM, EPEC and other controllers. The process: - First you need to install the appropriate driver. Link: https://www.peak-system.com/Drivers.523.0.html?&L=1 - Restart the computer - Start the CoDeSys application - Change the name of the adapter in Communication parameters, as mentioned in previous comment. Write the name exactly as written "Peak_USB", as it could also be case sensitive (defines which .dll file to use). If this doesn't work I would contact the vendor of the controller to find out the procedure. In the attachment I've added a FAQ document from IFM regarding using PCAN USB. P.S. I've noticed in your picture of communication parameters a channel via TCP/IP is mentioned. In this case a USB to CAN connection is not being used. First you should change the channel/gateway to connect via CANbus or connect using an Ethernet cable.
