BCD data hold -Level input-
Renewal of the BCD data output signal is stopped. (The indicated value is not held.)
Also the STROBE output is turned OFF.
It is carried out by pin A14.
Logic switching -Level input-
Switch the output signal logic with pin B14.
■BCD output mode
Set the BCD output mode of F331.
Linked with indicated value
Output linked with indicated value.
When the indicated value is held, the held value is outputted even if the sensor input signal changes.
Not linked with indicated value
Scaled output linked with sensor input.
Even if the indicated value is held, an output is made according to the changes in sensor input
signal.
■BCD data update rate selection
Normaly, BCD data update synchronous the A/D conversion (300 times/sec.).
When the BCD input equipment is low ability and can not read out the high rate of 300 times/sec.,
set the BCD data update rate is low.
■BCD external output selection
Output signal can be assigned.
Select from OK, NG, HH, HI, LO, and LL.
When level input is OFF, output signal is hold release.
Hold release Hold
Undefined section (20ms or less)
OFF
ON
When level input is ON, output signal is hold.
When level input is OFF, output signal is negative logic.
Negative logic Positive logic
Undefined section (20ms or less)
OFF
ON
When level input is ON, output signal is positive logic.
