< Read command mode (Mode 2) >

When the instruction input comes ON with the operand B+1 is 2, the Read command mode
(mode 2) is selected. In this mode, the T1-16S sends the user specified Read command to the
Inverter specified by the operand B, and repeats.

Sends the specified command to #n Inverter

Receives the response and stores the data into the register

The target Inverter number #n is specified by the operand B.
The scan execution status and the Inverter communication status are stored in the operand
B+2 to B+7.
The command setting register and the response data storing register is indirectly specified by
the operand A and A+1.

When the instruction input is reset to OFF, the operation is stopped after receiving the
response from the Inverter.

When the data for each operand are set as above, the following operation condition is specified.

RW200=3

The target Inverter number is 3. Therefore T1-16S communicates with #3 Inverter.

D1000=4 & D1001=3000

D3000 is specified as the command setting register and D3001 is specified

as the response data storing register.

Example operation:

For example, to read the output current from the #3 Inverter, set the command code HFE03 into
D3000. Then the response data is stored in D3001. If the response data is 1915, it means 19.15 %.
For the command code and the data format of the response, refer to your Inverter manual.
