Explanations of PLC Setup Settings

Basic I/O Unit Input

Response Time

IOM Hold Bit Status at

Startup

The input response time can be set for Basic I/O Units by Rack and Slot num

ber. Increasing this value reduces the effects of chattering and noise.

Decreasing this value allows reception of shorter input pulses, (but do not set

the ON response time or OFF response time to less than the cycle time).

Pulses shorter than the input

response time are not received.

Input response time Input response time

The default setting for the input response time is 8 ms and the setting range is

0 to 32 ms. When the input response time is set to 0 ms, the only delay will be

the delays in the Unit’s internal elements. For information on the Unit’s internal

elements, refer to Appendix A Specifications of Basic I/O Units and check the

input response time for the Unit that you are using.

The input response time settings are transferred to the Basic I/O Units when

the PLC is turned ON.

When the Unit’s settings are changed, they are stored in A220 to A259 (Actual

Input Response Times for Basic I/O Units). When the settings in the PLC

Setup have been changed with the PLC in PROGRAM mode, the PLC Setup

settings will differ from the actual settings in the Units. In this case, the values

in A220 to A259 can be checked to see the input response times actually set

in the Units.

The IOM Hold Bit (A50012) can be turned ON to retain all of the data in I/O

Memory when the CPU Unit’s operating mode is switched between PRO

GRAM mode and RUN/MONITOR mode. When the PLC is turned on, the

IOM Hold Bit itself will be cleared (OFF) unless it is protected with this PLC

Setup setting.

If the IOM Hold Bit Status at Startup setting is ON, the status of the IOM Hold

Bit will be protected when the PLC is turned on. If this setting is ON and the

IOM Hold BIt itself is ON, all data in I/O memory will be retained when the

PLC is turned ON.

Note If the backup battery fails or is disconnected, the IOM Hold Bit will be cleared

whether this setting is ON or OFF.
