A6.13 Input terminal’s
positive and negative logic
Fig.6-24 terminal’s positive and negative logic
A6.13 defines the input terminal’s positive and negative
logic
Positive logic: Terminal Xi is enabled if it is connected
to the common terminal;
Negative logic: Terminal Xi is disabled if it is connected
to the common terminal;
If the bit is set at 0, it means positive logic; if set at 1, it
means negative logic.
For example:
If X1~X4 are required to be positive logic, and X5 is
required to be negative logic,then the settings are as
following:
Logic status of X4~X1 is 0000, and the hex value is 0.
Logic status of X5 is 001, and the hex value is 1. The
display on LED decade is 1; so the value in A6.13
should be set as 10..

Note:
Factory setting of all the terminals is positive logic.
A6.14 Bi-direction pen-collector
output terminal Y1
A6.16 Output functions of relay R1
Refer to chapter 3 for the output characteristics of Y1
that are bi-direction open-collector output terminal and
the relay’s output terminal. Table 6-6 shows the
functions of the above 2 terminals. One function can be
selected repeatedly.
