IR Area Settings and Functions
Section 9-3
Counters 1 and 2 will be set to the same sampling time if word n bits 01 and
02 are set to 1.
Internal Control IN1
(Word n Bits 08 or 10)
Internal Control IN2
(Word n Bits 09 or 11)
These bits will be used as control input signals if internal control IN1 and IN2
are set in word m+1 bits 04 to 07 and word m+2 bits 04 to 07.
Control input IN1 is used to start the High-speed Counter Unit in gate and
sampling modes. At the rising edge of the control input IN1, the counter value
is reset and the Unit is started.
The count value is reset at the rising edge of control input IN1 in cumulative
gate mode.
The counter starts counting at the rising edge of control input IN2 in cumula-
tive gate mode. The counter stops counting at the falling edge of control input
IN2 and the count value is kept on hold.
The counter is in operation again at the rising edge of control input IN2, start-
ing from the count value kept on hold.
Read Error (Word n Bit 06)
If an error results, the Error Flag (word n+6 bit 15) will be set to 1, at which
time the error codes will be output to word n+7 when word n bit 06 is set to 1.
The error data is set to 0 when all the error data is read. Repeatedly turn this
bit ON until the error data is set to 0.
Error Data:
Present Counter Value
(Words (n+2) and (n+3) or
(n+4) and (n+5))
These words are used to store the present counter values of the counters.
The above is a setting example in BCD.
The following data is stored.
BCD:
–8,388,608 to 8,388,607
Hexadecimal:
800000 to FFFFFF (–8,388,608 to –1) and 000000 to
7FFFFF (0 to 8,388,607)
Error location
Two rightmost DM digits are indicated.
