Technical Specifications

Version & Model Difference

The NHPL046751 R2 is the second revision of the NHPL046751 module. The R2 version includes an upgraded processor (from 100 MHz to 200 MHz) and increased program memory (from 256 KB to 512 KB). Additionally, the R2 version adds support for Profibus DP protocol, which was not available in the original version. The communication interfaces remain the same, but firmware updates have improved the response time for Modbus TCP and added enhanced diagnostic functions.
