6-11-1 I/O Response Time Settings
The input response times for CS/CJ Basic I/O Units can be set by Rack and
Slot number. Increasing the input response time reduces the effects of chat-
tering and noise. Decreasing the input response time (but keeping the pulse
width longer than the cycle time) allows reception of shorter input pulses.
Note With CS-series CPU Units, pulses shorter than the cycle time can be input
with the high-speed inputs available in some C200H High-density I/O Units or
with a High-speed Input Unit. Refer to
6-1-4 High-speed Inputs for details.

Operation with a Battery
Required data?
Maintain previous
I/O data at
startup?
Use normal operation. No
Memory Card is required.
PLC Setup: Disable detection a
low battery voltage and set I/O
Memory Hold Bit status to be
maintained at when power is
turned ON.
Battery-free Operation
Initialize only DM Area
words allocated to CPU
Bus Units and Inner
Boards (D20000 to
D32767)?
Initialize all of the DM and EM Areas
starting from D00000.
Automatically transfer data from a
Memory Card at startup.
Required files: AUTOEXEC.OBJ,
AUTOEXEC.STD, and
AUTOEXEC.IOM
