7.3.3 Input terminal response time
- The input terminal response time function allows you to specify a sampling time for each of intelligent input terminals
1 to 5. You can use this function effectively to remove noise (e.g., chattering).
- If chattering hinders constant input from an input terminal, increase the response time setting for the input terminal.
Note that an increase in response time deteriorates the response. The response time can be set in a range of about 2
to 400 ms (corresponding to settings of 0 to 200).
Item Function code Range of data Description
Response time of intelligent
input terminals 1 to 5
C160-C164 0. to 200. Variable in step of 1
Note: When the power supply is OFF-> ON or reset , this function is invalid.
7.3.4 Intelligent output terminal setting
You can assign the functions described below to the intelligent output terminals [11] (C021) and the alarm
relay terminal (C026).
The intelligent output terminals [11] is used for open-collector output, and the alarm relay terminal is used
for relay output.
You can select the a-contact or b-contact output for individual output terminals by using functions "C031"
and "C036".
