The self-diagnostic error code is stored here
when a self-diagnostic error occurs.
Switches the FP-escreen to the screen of the
mode specified.
K0: N mode first screen
K1: N mode second screen
K2: S mode first screen
K3: S mode second screen
K4: R mode first screen
K5: R mode second screen
K6: I mode first screen
K7: I mode second screen
Ch.0 analog input data (2-word real data)
Ch.1 analog input data (2-word real data)
One shift-out hexadecimal digit is stored in bit
positions 0 to 3 when the data shift instruction,
F105 (BSR) or F106 (BSL) is executed. The
value can be read and written by executing the
F0 (MV) instruction.
The divided remainder (16-bit) is stored in
DT9015 when the division instruction F32(%)
or F52(B%) instruction is executed. The
divided remainder (32-bit) is stored in DT9015
and DT9016 when the division instruction
F33(D%) or F53(DB%) is executed. The value
can be read and written by executing the
F0(MV) instruction.
After commencing operation, the address
where the first operation error occurred is
stored. Monitor the address using decimal
display.
The address where an operation error
occurred is stored. Each time an error occurs,
the new address overwrites the previous
address. At the beginning of a scan, the
address is 0. Monitor the address using
decimal display.
The data stored here is increased by one
every 2.5 ms. (H0 to HFFFF)
Difference between the values of the two
points (absolute value) x 2.5 ms = Elapsed
time between the two points.
