HOPF 7515 communication protocol communicates with the Mains Voltage Ana= lysis Board 7515 card, which is an optional part of the GPS system HOPF Sys= tem 7001. The 7515 card includes the system for measuring and monitoring of= the network frequency (between 45 and 65 Hz). The communication is only on= e-way. Data are sent via serial line. These data are sent:
Non
I/O tag types: Ai, Ci, TiA, TiR, TxtI.
You can configure the following I/O tags:
Table 1
Address | Type | Meaning |
---|---|---|
0 | all | The system time that is sent in the hh:mm:ss for=
mat . Depending on the I/O tag type, it contains:=20
|
1 | all | Network time that is sent in the hh:mm:ss format=
. This time is calculated from the network frequency (if the frequency=
is optimal, i.e. 50Hz or 60 Hz, network time is equal to the system one).&=
nbsp; There are the same rules for both the system time and network time. |
2 | TiR,TxtI | Difference between the system time and network o= ne. |
3 | Ai,Ci,TxtI | Network frequency in Hz. Depending on the I/O ta=
g type, it contains:=20
|
7 | TiA,TxtI | System time and date that is sent once a minute.=
Depending on the I/O tag type, it contains:=20
