Analog Output Terminals Section 7-5
Output Range: 0 to 20 mA The values 0000 to 1770 hex (0 to 6,000) correspond to the current range 0 to
20 mA. The output range is 0 to 21 mA.
DA Conversion Data DA conversion data is output from the Master as shown in the following dia-
gram.
When outputting negative voltages, specify the DA conversion data as two’s
complements. The NEG instruction can be used to obtain two’s complements
from absolute values. When pin 7 of the DIP Switch is turned ON, the DA con-
version data will be expressed in signed binary.

7-5-2 I/O Data Types and Allocation Methods
Analog Output Terminals support one type of output data and input data
(Generic Status Flags) each. I/O can be allocated in the Master using one of
the following three methods.
1,2,3... 1. Allocating only analog output values (default I/O data) in the Master.
2. Allocating selected I/O data.
3. Allocating user-defined I/O data.
