8.2. Content of the Gateway’s DPRAM Memory

The LUFP9 gateway’s DPRAM memory contains all of the data exchanged between the gateway and the 8 TeSys U motor starters, as well as two special registers only exchanged between the gateway and the DeviceNet master (words used for managing the downstream Modbus network).

The flow of data exchanged between the TeSys U motor starters, the gateway and the DeviceNet master is shown below, in order to highlight the role of the gateway’s memory in these exchanges:
