Hi everyone, I'm working on a project where I need to exchange data between a Siemens S7-1200 PLC and an Allen-Bradley MicroLogix 1400 PLC. The Siemens PLC is the master and the AB PLC is the slave. The data consists of a few integers and booleans, and the communication needs to be fast and reliable. I'm looking for the best way to achieve this, and I'm considering the following options:
• Using an Ethernet/IP adapter module for the Siemens PLC, such as the CM 1243-5, and configuring the AB PLC as an Ethernet/IP scanner. This would allow me to use the standard Ethernet/IP protocol to read and write data between the PLCs, but I'm not sure about the compatibility and performance of this solution.
• Using a Modbus TCP adapter module for the Siemens PLC, such as the CM 1241, and configuring the AB PLC as a Modbus TCP client. This would allow me to use the widely used Modbus TCP protocol to exchange data between the PLCs, but I'm not sure about the ease and flexibility of this solution.
• Using a serial communication module for the Siemens PLC, such as the CM 1242-5, and connecting it to the RS-232 port of the AB PLC. This would allow me to use a custom protocol to send and receive data between the PLCs, but I'm not sure about the speed and reliability of this solution.
Has anyone here tried any of these options, or have any other suggestions? I would appreciate any advice or feedback from fellow PLC experts. Thank you for reading my thread and I hope to hear from you soon.
