■ ■ ■ ■ Displaying I/O signal status in hexadecimal format
Each I/O terminal is assigned to bit 15 through bit 0 as listed in Table 3.11. An unassigned bit is
interpreted as "0." Allocated bit data is displayed on the LED monitor in 4-digit hexadecimals ("0" to
"F" each).
With the FRENIC-Mini, digital input terminals [FWD] and [REV] are assigned to bit 0 and bit 1,
respectively. Terminals [X1] through [X3] are assigned to bits 2 through 4. The value "1" is set for
each bit when the assigned input terminal is short-circuited (ON) with terminal [CM]. The value "0"
when it opens (OFF). For example, when [FWD] and [X1] are ON and all others are OFF, the
display on LED4 to LED1 would be 0005.
Bit 0 is assigned to digital output terminal [Y1]. The value "1" is set when the terminal is short-
circuited with [Y1E], and the value "0" is set when it opens. The status of the mechanical relay
contact output terminal [30A], [30B] and [30C] are assigned to bit 8. The value "1" is set when the
circuit between output terminals [30A] and [30C] is closed and the value "0" when the circuit
between [30B] and [30C] is closed. For example, if [Y1] is ON and the circuit between [30A] and
[30C] are short-circuited with each other, then the display for LED4 to LED1 would be 0101.
How the hexadecimal display is configured for the terminals to which bits 0 to 15 are assigned and
the 7-segment LED is shown below.

* (XF) and (XR) are reserved for communications. Refer to "[ 2 ] Displaying control I/O signal terminals under
communication control" below.
[ 2 ] Displaying control I/O signal terminals under communication control
There are two control circuit input displays under communications link control – "display with
ON/OFF of the LED segment" and "in hexadecimal format" for input commanded from RS485
communications link. The content is similar to that of the control circuit I/O signal terminal status
display; however, (XF) and (XR) are added as inputs and nothing is assigned as output terminals.
Refer to the user’s manual of RS485 communication for details on command inputs through
RS485 communication.
