SV- iV5 offers a read-only and a write-only area for all the external communication cards. The read-only
area is the place that saves data transmitting from inverter to the communication card. User program of
the master uses the area to check the information of the inverter through the communication card. You
can set up a number of addresses to use (from 1 to 8) at EXT_10[Output Num].
The write-only area is saved with sending data from the communication card to inverter. It is the area
where user program of the master uses to run a command which comes through the communication card.
You can set up a number of addresses to use at EXT_19[Input Num].
At the communication, the read-only area is 0x0100~0x0107 and the write-only area is 0x0108~0x010F.
Refer to the above table about addresses to share data.
In case of SV-iV5, areas which can be used at the communication are as follows:
1. Common area beginning with 0x0000.
2. SV-iV5 communication-only data area starting from 0x0100 of the common area.
3. Reference data area starting from 0x0500 of the common area.
4. Group address area.
There is a reason that no.2 is added above. It does not need to read 0x0001 because an ordinary read
command reads from 0x0000 to 0x0002 on 485 communication. To avoid reading same area repeatedly,
parameter settings are as follows. Set EXT_10 as 2, EXT_11 as 0x0000, EXT_12 as 0x0002, and then do
read command with the master to read 2 addresses from 0x0100. It reads data only from 0x0000 and
0x0002.
