5.3. Port Polarity
The polarities of input/ output ports in the software are specified in terms of the switch type: the
polarity of a normally closed switch is “P”; the polarity of a normally open switch is “N”. The
corresponding relation between system port No. and ports on the terminal board is as shown in Table 7
and Table 8.
The steps to modify port polarity are as following: press “Menu”→ 8. Diagnosis→ 2. Port List, and
then press [OK] to enter the interface as shown in Fig. 5-4. At this time, you can press the “Up” or
“Down” key to move the cursor to the desired port, and then press the “Shift” key to change its polarity.
After its polarity change, press [OK] to save the modification.
