Input response time setting Time constants can be set for inputs from Basic I/O Units.
The time constant can be increased to reduce the influence
of noise and chattering or it can be decreased to detect
shorter pulses on the inputs.

When downloading projects from CX-Programmer Ver. 5.0 or
higher, symbol table files (including CX-Programmer symbol
names, I/O comments), comment files (CX-Programmer rung
comments, other comments), and program index files (CX-
Programmer section names, section comments, or program
comments) are stored in comment memory within the flash
memory.
