(Post)
Hi everyone, I’m using an IFM ecomatBasic CR413S controller and having trouble connecting it to CODESYS 3.5. I have CODESYS SP18 installed, as recommended in the manual, and I’ve tried different patches. I’ve also installed all the packages provided on the IFM website for this controller. I can successfully connect to the ecomatBasic template, but I’m unable to connect when using the CR413S-specific template that includes all the inputs and outputs. Has anyone encountered this issue or knows a solution? Best regards, Jan

I have a Codesys-based Eurotherm E+PLC400 connected to Codesys HMI SL for visualization. I am also bringing in several Pressure Indicators via the Ethernet. Everything works; however, the Pressure indicators sometimes read a negative value. When they do, the displayed value on the screen reads "65532." While I know what it represents, the customer freaks out and wants it to read "0" or a negative number. The value comes in as an integer, just in case that matters. Does anyone have any ideas?

Are these variables already declared in the IO list? It looks like it's trying to create new variables instead of mapping them to the existing ones.

Does anyone know how to access the ModbusTCPSlave_Diag.ComState without declaring each one by the device name? I attached them to an array but since I may have dozens of devices this is still a bad solution.

Hi All, I have problem with ModbusFB.ClientSerial. I'm using 4 different port for Modbus communication. After some time of running program ClientSerial stops to receive data to reply buffer and all request finish with Reply Timeout. The Device sent reply correctly,that it is visible on oscilloscope and it is possible to see that data( reply )are in the device. If the usbtty device is read over external app. then it is possible to see all data which were not taken by ModbusFB.ClientSerial. The stack does not overflow or something , program runs correctly forward and no exceptions or something. The main problem it is that when the error occur than it is not possible to reset port or something or maybe i'm doing it wrong way. please help me with this issue. Thank you for any help in advice Milan
