Cautions
• In 14-point and 24-point type FX
connector 1, and occupies communication channel ch1.
In this case, the communication function using communication channel ch1 is not available when the VRRD or
VRSC instruction is used.
• In 40-point and 60-point type FX
option connector 2, and occupies communication channel ch2.
In this case, the communication function using communication channel ch2 is not available when the VRRD or
VRSC instruction is used.
• The communication function is not available for ch1 when the VRRD or VRSC instruction is used in the program in
FX /FX PLCs.

Analog values of variable
potentiometers are stored in data
registers D200 to D207.
Because T0 to T7 are 100
ms timers, 0 to 25.5 sec are
obtained from the set values
0 to 255.
