hello Joe, I attach the program. Let's see if you can help me. The unilogix version would be the last. Luis 20231228REV19_LUIS_2.ulpr

Thank you very much Saragani I already have the communication bits identified. As I mentioned in the initial question. Modbus communication is disconnected and data is frozen for no apparent reason. using modbus TCP/IP. and 20 periodic records. I try to see if packets are lost or any communication errors are generated. What is more advisable to do to read modbus. Periodic or Aperiodic based on time? Luis

hello In unilogic where are the system bits, how does the unilogic have it? I am having problems with the TCP/IP communication of a unilogic. It is frozen and it is necessary to reset. Does anyone have any suggestions? Luis

hello I have a communication problem using modbus tcp ip between a Sick gas analyzer and a PLC/HMI US5/7-X10-TA30. The communication works perfectly until it disconnects by itself and the data freezes. Can you tell me where some diagnostic bit? What are the SBs like in the visilogic? Do you have any clear diagnostic tools? to see the accumulation of errors or to allow me to diagnose the communication. Luis

Hi Joe and Flex. First of all, thank you very much for the time you spend on this. Secondly, I give you the program running. Where I apply many of your instructions. Which led me to be able to connect a SAMBA SM70 HMI to a BAUMER i/olink. As Joe indicated, the RHR issue had to be resolved. and the initialization of the square so that it connects automatically. See the clock I set with SB150 in lines 2 and 3. I leave you the application in case it is useful to you. Luis Luis_REV_22.vlp

Hi Joe, thanks for your response. When I uploaded the file, I continued working and deleted the modbus scan block. The problem I have is that the program works as a master. I already fixed the differences with socket 3. But it disconnects when the SB150 drops. and when it appears again it reconnects. What I cannot achieve is that the modbus connection is maintained. I'm going to investigate a little what you wrote to me in the previous response. and then I comment again I leave the program a little more advanced. Luis Luis_REV_10.vlp

Hi flex727 and Joe I have been working on the communication of an i/olink Baumer with a SAMBA HMI. The Holding records are divided into 4 parts, 41001 + 10, 42001+10, 43001+10, 44001. For this, I was able to carry out the program that I attached. The program works but what is causing me problems is that the SB150 disconnects from time to time. and stop reading the logs. SAMBA = master and BAUMER = slave. I need communication to be continuous. Can you help me? Luis Luis_REV_11.vlp

Hello Unitronics support. Iam currently working with an PLC Samba in a program for communication modbus with an IO-Link card with Ehternet communication. But I not can set the plc as master in the network. In the program I used the block MODBUS IP read holding register for read the address target in the IO-Link device. But the block shows in the status messages when is started the number 5, which means that it has no response from the IO-Link device. I attached the program in this email so you can see if I have any errors in the programming. The PLC Unitronics samba have the device feactures detailed below: Unitronics samba OPLC Information: Model: SM70-J-TA22 Hardware Rev: B OS Version: O/S: 4.11 (28) I check the devices by Modbus poll and obtain the data detailed below: Data etherNET/IP IO-Link master Baumer // PN: 11215460.

I wait attentively for your reply. Kindest regards. 2023-12-13 Modbus master.vlp
