Clock Synchronization with the RTU Protocol Facilities
Original instructions
About us
Overview
One of the main features of the RTU is to manage events with time stamping. Time stamping requires effective time synchronization.
Behavior
The behavior of the clock synchronization command is determined by the role of the BMENOR2200H module:
Role(s)
Description
slave/server
When acting as a DNP3 slave or server, the BMENOR2200H module can synchronize its clock with a master or client station (SCADA). When your enable this feature, the module receives the clock synchronization command, it updates its internal clock, and posts the new value to the CPU. This maintains a consistent time on the local rack.
master/client
When acting as a DNP3 master or client, the BMENOR2200H module sends clock synchronization commands to connected slaves. As with the case above, the clock is initialized from the CPU when it starts up. It gets the new time from the CPU every time master/client sends the time synchronization command.
NOTE: When acting as both a master/client or slave/server, the BMENOR2200H module periodically synchronizes its local time with that of the CPU through the rack.
Configuration
The SNTP client runs only when you configure the service in the DTM. To configure the SNTP service, refer to the clock synchronization instructions.
