Coincidence output

Coincidence output is a function by which a signal can be output when a value set by the coincidence output point
write instruction (ICCOVWR1(P)) matches the CH1 Current value (SD1880, SD1881) ( Page 250, Section 8.10.1
(6)). Two kinds of coincidence outputs (No.1 and No.2) are provided for each channel.
Ex. When the Coincidence output No.1 signal is turned on
CH1 count enable command
(SM1895)
CH1 coincidence output
enable command (SM1892)
Coincidence output No.1
point setting
CH1 counter value smaller No.1
(SM1882)
CH1 counter value coincidence
No.1 (SM1881)
CH1 counter value greater No.1
(SM1880)
CH1 current value
(SD1880 and SD1881)
Coincidence output No.1 signal
CH1 coincidence signal No.1
reset command (SM1890)
