Hi Experts, I am having now a Project that my PLC 1512SP have to read data from 2 EKE 1B Danfoss Superheat controller via MODBUS TCP. I am using gateway to change the Modbus RTU from Danfoss controller to MODBUS TCP and then connect it to my PLC. But i can read data from only the Danfoss controller 1. Here is more detailed. Gateway IP/TCP :192.168.0.254 -->16#C0.16#A8.16#00.16#FE Danfoss controller 1: Slave ID :5 Danfoss controller 2: Slave ID :10. I configure both of MB_Client Connect (in Imager 3 and 6) and give the Slave ID 5 and 10 for MB_Client_DB in system block (Image 2 and 5). In there i found out that the TDIAG_Status data of my Danfoss controller 2 is not correct(Image 5). Best Regards Attachmentpdf24_zusammengefügt.pdf (564 Downloads) |

Hi! Sorry but I think you have created several topics with this thread. The image has stayed here :P STATUS 7006 of the modbus client function indicates that data is being received. There may be a problem with the transfer. Have you tried using software to evaluate connection quality?
