Hello Arunraje, here you can find information about the necessary software: How can you establish OPEN MODBUS / TCP communication from a SIMATIC S7 and where can you find further information? What does BOM mean? I have no clue... Regards Sakura |

You just need a CP443-1 or a PN CPU (the choice is yours) and the open modbus TCP software available here. |
Programming today is the race between software engineers building bigger and better idiot proof programs, and the universe producing bigger and better idiots. |

BOM Stands for 'Bill Of Material' |

Dear ArunRaje, You need a CP443-1 or a PN CPU and the open modbus TCP software. Redundant Modbus TCP is possible with CP443-1. However redundant option is not possible via PN (Profinet) CPU. Option 1: ( Redundant Modbus TCP via CP443-1) Find below the different options for MODBUS TCP Communication Option 1 ( Redundant MODBUS TCP via CP 443-1) 1. CP443-1 MLFB NO: 6GK7443-1EX20-0XE0 2. S7- OPEN MODBUS/TCP REDUNDANT FOR S7-400 H SYSTEMS, SINGLE LICENSE MLFB NO: 2XV9450-1MB11 Option 2 : (Nonredundant Modbus TCP via CP 443-1) 1. CP443-1 MLFB NO: 6GK7443-1EX20-0XE0 2. S7 - OPEN MODBUS/TCP FOR NCM_CP, SINGLE LICENSE, ON CD MLFB NO: 2XV94501MB00 Option 3: (Modbus TCP via Profinet Interface of the CPU) 1. CPU 412-5H 2. S7- OPEN MODBUS/TCP FOR PN-CPU SINGLE LICENSE, ON CD MLFB NO: 2XV94501MB02 Option 4( MODBUS TCP via Profinet Interface of S7-1200 CPU) For this case u need to consider only S7-1200 CPU. There is no need to consider any additional license. This is a cost effective solution for MODBUS TCP Communication AttachmentModbus_TCP_Flyer_English.pdf (788 Downloads) |

Thank you for that detailed information. But the flyer that you uploaded is not up to date, e.g. the information about the function codes are no longer correct and not all the products are listed. So I would always recommend to check this page: S7 OpenModbus/TCP It's information is always up to date. Regards Sakura |
