HELLO experts ,can some body heple me , we are preparing a network topology where there are : 1- principal PLC CPU 412-5H with two CP 443-1 modules 2- there are 18 clients PLC communicate with the principale PLC CPU 412-5H 3-from this 18 client , there 4 clients based of siemens PLCs S7-1500 where on this PLCs is based on 8 modules ET200sp on ring 4-two CP 443-1 communicate with DCS master Honeywell EPKS question and clarifications : * Is it onThis configuration the CPU S7 412 5H Can communicante with this clients ? *how many device partner can CPU communicate on modbus tcp/ip? * is it this configuration is right? * can we avoid the problem of loop ON COMMUNICATION with the clients,? *we use HMI TP2200 comfort ,can we archive the data from the 18 clients ? *Can we have interruption of communication with the clients according to the number of clients ? attached: network topology azote generator Attachmentnetwork topologie .pdf (809 Downloads) |

Hello ICSramzi;
Your post asks any questions, many of the answers we can provide will depend on the hardware nd software versions you are using. For example, what model of CP 443-1 do you have, and are you using redundant Modbus TCP drivers for CP 443-1, such as this one, in this project: SIMATIC Modbus/TCP Redundant communication via the CP 443-1 in H-systems (6AV6676-6MB30-4AD0) https://support.industry.siemens.com/cs/us/en/view/109739212/115818551691 The manual above can answer most of the questions you are asking, others have been included in the screenshot below, such as the fact that the CPUs you are using support up to 48 connections, and that the HMI you plan to use supports up to 50 separate archives of 50,000 items each (from their Technical Data sheets). So your selected hardware seems to be adequate for this confguration. One thing needs to be clarified. Are you initiating the request of data in the S7-412-5H CPUs (through the CP 443-1s)? Are the S7-1500 CPUs in the project replying to the S7-412-5H requests? in that case, you must consider the client as this S7-412-5H, and the other CPUs as servers. https://en.wikipedia.org/wiki/Client%E2%80%93server_model "Clients and servers exchange messages in a request–response messaging pattern. The client sends a request, and the server returns a response." Hope this helps, Daniel Chartier |

thank you for replying One thing needs to be clarified. Are you initiating the request of data in the S7-412-5H CPUs (through the CP 443-1s)? Are the S7-1500 CPUs in the project replying to the S7-412-5H requests? in that case, you must consider the client as this S7-412-5H, and the other CPUs as servers. for your information 1-CPU 412-5H is the main PLC where i read /write data from S7-1500 CPUs in the project using communication modbus TCP/IP type PN between two CPUs 2-DCS honeywell need to read/write data from the principal PLC CPU 412-5H over CP443 TCP/IP *Can you help me wich bloc& modbus package i need to use? * Can we avoid on DCS honeywell the problem of loop ON COMMUNICATION with the clients S7-1500 CPUs,? |
