5.9 AFI MVS Driver
RTU Driver : AFI MVS Driver V1.1
KeyCode : AFI
The AFI Driver is functionally equivalent to Modbus (See Modbus). The difference lies in
the auto-time synchronization feature. Two items must be properly configured for the AFI
auto-time synchronization feature to work properly.
To enable the feature, a point must be added as follows.
PID INDEX ADDRESS F1 F2 F3 F4 TYPE
? ? ? 40000 502 0 0 (UINT)
The point must also be included in a pollset, which is polled on a regular basis. It is
suggested to use poll-set 2 and schedule the record to be read hourly. If ever this register
returns with either bit0, or bit1 set (=1), a time synchronization is required and the driver will
write the correct time to the AFI's date/time registers automatically.
In order for the correct LOCAL time to be written to the AFI meter, the correct TIMEZone
must be configured in the PAC.
Driver configuration is the same as Modbus.
RTU
TYpe AFI – Set the RTU driver to AFI.
