Hai, I need to establish the communication between Siemens s7-400H plc and GE controller using Modbus on TCP protocol. GE will be sending query, accordingly we need to exchange data. Sending actual values, also receiving setpoint/ command. I was going through links and forum discussion on modbus and got little idea from our friends here. Now i need to more clarity on my doubts. Hardware available with me. CPU 6ES7 412-3HJ14-0AB0 - - - Firmware V 4.5.5 Boot Loader Firmware expansion V 4.5.0 CP 6GK7 443-1GX20-0XE0 Hardware 5- - - Firmware V 2.1.12 Boot Rom Firmware expansion V 1.2.0 Now as per FAQ, Firmware V 2.1.12 will not support modbus TCP communication. So we will update FW of CP card. 1. currently one HMI is communicating with this CP card as shown in attachment. If we are using this CP for modbus communication, HMI communication will get interrupted ? If so, what best alternative can be used? HMI connected @ P1 port of PNIO group(GBIT port, nothing is connected) 2. 2XV9450-1MB11 is the only software/License i need to purchase? 3. Modbus/TCP RED V2 , This link is giving one software setup to make Modbus communication wizard. Is it correct? Kindly give your valuable suggestions... |

Hi Vipz, Parameterization and connections(Single sided/Double sided) need to be configured via Modbus TCP wizard. Modbus blocks must be licensed else INTF will blink in your H CPU. Take a look at below link and the attachment. http://support.automation.siemens.com/WW/view/en/33118723 Refer the below entry for the released ports and CPU Firmware versions. http://support.automation.siemens.com/WW/view/en/34010717 Regards Antony AttachmentModbusTCP_NCM_CP_Red_V2_English.pdf (291 Downloads) |

Hi prabhakaran, - the new Simatic Modbus/TCP CP RED version is now also configurable with the Modbus Wizard. - Also it was adapted in useage to the other Modbus/TCP products. - Some Bugs concerning bit (Coils) writing has been fixed. - And you can now insert more Licence Keys in the Licence DB if you want to register CPUs in advance (spare part case). - Moreover, up to now there is only one Modbus Wizard which contains the possibility to configure all Simatic Modbus/ TCP versions. 6AV6676-6MB30-3AX0 SIMATIC Modbus/TCP CP RED SIMATIC Modbus/TCP CP RED for S7-400 H systems, Single license on DVD https://support.industry.siemens.com/cs/ww/en/ps/6AV6676-6MB30-3AX0 https://support.industry.siemens.com/cs/ww/en/view/60735352 Greez Bachgeist |
