There are no blocks for Modbus TCP on the system side. The example (Link FAQ) mentioned was developed for the Modbus TCP commands used by Siemens panels by default. With other participants maybe come to restrictions . https://support.industry.siemens.com/cs/ww/en/view/109482437 Otherwise we know one example from the project generator, which reads values from a SENTRON PAC via Modbus TCP (in "MachineDataAcquisition"). https://support.industry.siemens.com/cs/ww/en/view/51339107 Alternatively you could use a simple SIMATIC (possibly already present in the project) e.g. connected via I-Device and using the Modbus TCP client block as gateway. Or you can use an appropriate gateway, e.g. from Anybus or Hilscher, etc. |

additional Modbus communication please find some information in FAQ Number of possible Panels at SIMOTION / HMI-ModbusTCP-Driver for SIMOTION https://support.industry.siemens.com/cs/ww/en/view/109482437 The FAQ is written with expanation Siemens HM but also Delta HMI should have some settings for update time. According to AWB https://support.industry.siemens.com/cs/ww/de/view/109482437, update times of 100ms are possible in principle. Depending on the runtime of the background task of the SIMOTION, this update time may not be observed. But: It is recommended to set the update times of the variables in TIA WinCC Advanced not smaller than 500ms. 2. The load of the SIMOTION only helps with regard to the background task, this will normally only amount to a few ms. 3. the variables are requested by the HMI and only these are sent back, nothing can be optimized here. |
