Output Type Setting; Parameter Setting By Software - Toshiba AD268 User Manual

3. Output Type Setting

3. Output Type Setting
The DA264 supports multiple output ranges, 5V, 10V, 0 to 5V, 0 to 10V, 1 to 5V, 0 to 20mA,
or 4 to 20mA. The output range is selected by writing the parameter into the DA264 by the T2
program. The voltage or current output is selected by the DA264's output terminals.
The general flow for setting the output type is as follows.
(1) Mount the DA264 onto the T2 rack.
(2) Turn on power to the T2 system.
(3) Execute I/O allocation.
(4) Program the "output type setting program". (see below)
(5) Turn the T2 to RUN mode.

3.1 Parameter setting by software

The output range of the DA264 is specified by writing the following parameter data into the
DA264's buffer memory. To write the parameter into the buffer memory, T2 user program
(WRITE instruction) is used.
These parameter data are not maintained in the DA264. Therefore, program the output type
setting routine and execute it at each time of the beginning of the operation.
