Hi, o As client, Active Established should be “Ture” and remote port should be set with the server port number · MB_DATA_PTR could has absolute or symbolic address: Typ: there are two "ID's" in this context: 1 - the ID that belongs to internal CPU communication resources. This number belongs just to the CPU. Should be an unique number in the CPU project (each communication has its own number). it stay on the CONNECT struct 2 - the ID that belongs to modbus tcp addressing. E.g. it is not used (let as default value). Some Modubs servers, however needs an specific ID to work. it stay to static variables of the MB_Client Block as MB_Unit_ID. Notes: In the post of 28/04/2018 I place a V15 project version + cast showing the project steps.

Dear expert, I checked your tested program with modbus client simulator.But it is not working.It shows 8383 errror.(Error reading or writing data or access outside the address area of MB_DATA_PTR. The error can occur locally as well as with the instruction "MB_SERVER".).Please treat this urgent.Am expecting your prompt response. |

Hi, I tried this sample program and am having a few issues on TIA portal Pro v13 with a S7-1516-3 PN/DP, firmware v1.1.2. The s7-1500 PLC is a Modbus client and so I am only using "MB_CLIENT_DB". 1) MB_DATA_PTR didnt accept a struct as in your example, "MB_CLIENT_DB".STATUS = error 818B: "The MB_DATA_PTR parameter has an invalid pointer." However, no complain with an array[0..2] of Int. 2) if Client_Send_DB.InterfaceId is < 64, "MB_CLIENT_DB".STATUS = error 809B: "The element InterfaceId within the TCON_xxx structure does not reference a hardware identifier of a CPU or CM/CP interface or has the value "0"." 3) if Client_Send_DB.InterfaceId is >= 64, "MB_CLIENT_DB".STATUS = error 8086: "The ID parameter is outside the valid range." I also attached my sample project to this post for info. AttachmentProject1.zip (1388 Downloads) |

Hi, Here there is a very simple sample projects to illustrate how it works: · S7-1500 as MODBUS server with S7-1200 as MODBUS client AttachmentC:\Users\z0008iwv\Documents\Bluetooth Exchange Folder\S7-1500 MODBUSServer.zip (3492 Downloads) |

Hi, sorry but I don't have a V13 version of it. Anyway, Here there are a V15 version of a demonstration program and casts showing about how it was created. The project uses S7-1500 (but the configuration is similar to S7-1200). The use of S7-1500 has the advantage to be simulated in PLCSIM Advanced. The casts could be used as basis to build a project from zero. AttachmentMODBUS.zip (2309 Downloads) |

Hi, with the internet examples, I made an example project between two s7-1200 (one as a server and the other as a client) maybe it can help you. use version 14 of the TIA PORTAL, CPUs with firmware version 4.2 and MODBUS instructions V4.1. The blocks were without optimized access. regards
