Revision 3.0
The TJ1-MC__ responds with these codes:
/i
If var_type is 82 or B0, and the response code is 0000, the TJ1-MC__
responds with:
/i
If var_type is C2, and the response code is 0000, the TJ1-MC__ responds
with:
/i
Write command
The FINS write command has these formats:
• If var_type is 82 or B0:
/i
• If var_type is C2:
/i
• If var_type is 30:
/i
The parameters can have the following values:
/i
The TJ1-MC__ responds with these codes:
element_count 1 <= element_count <= number of variables - start_address
Condition Response code
