Read/Write
The data bit sets operation to read or write.

Read/Write
command
13 and 12
Loop no.
The data bit sets the Loop Number to which the
read or write operation applies.
Loop 1 = 01, Loop 2 = 10
11 to 08
Bank no.
Sets the bank number to which the read or write
operation applies as 1-digit BCD data. Set executed
bank numbers from 1 to 8.
Read/Write
command
07 to 00
Command
Sets the command code (Refer to page 41) for the
read or write operation as 2-digit BCD data.
n+1
15 to 00
Write data
Set the SP for a write operation as 4-digit BCD data. The least
significant digit of the actual data matches the least significant
digit of the set value. Set the most significant digit to F for minus
(–) values. The write operation commences when the write
request flag (Wd (n+2), bit 00) turns ON.
n+2
15 to 12
Loop 1
executed
bank
number
Set the bank number currently executed for Loop 1 and Loop 2 as
1-digit BCD data. Executed bank numbers are from 1 to 8. If the
value is set out of this range, the bank number reverts to the
previous value.

Loop 1
RUN
This the Loop 1 Run/Stop bit. When it is set to 1, operation starts;
when it is set to 0, operation stops.

Not used. Set to 0.
04
Loop 2
RUN
This the Loop 2 Run/Stop bit. When it is set to 1, operation starts;
when it is set to 0, operation stops.

Write
request
Turn this bit ON to write the data in Wd (n+1), by means of this
command.
Turn this bit OFF after the Write Complete Flag (Wd (n+6), bit 08)
turns ON.

Loop 1 PV
Outputs the Loop 1 and Loop 2 PV (process value) as 4-digit
BCD data. For platinum resistance thermometer data, the least

Loop 2 PV
BCD data. For latinum resistance thermometer data, the least
significant digit is 0.1. Set the most significant digit to F for minus
(–) values.
n+5
15 to 00
Read data
Outputs the data read with the commands set with Wd (n). The
least significant digit of the actual data matches the least
significant digit of the set value. Set the most significant digit to F
for minus (–) values.

Not used. Each bit is set to 0.
11
Write error
Bit set to 1 when the write data exceeds the set permissible
range. The bit is automatically set to 0 when the Write Request
Flag (Wd (n+2), bit 00) turns OFF.
10 and 09
---
Not used. Each bit is set to 0.
08
Write
complete
Bit set to 1 when the write operation executed by means of the
command set with Wd (n) ends normally. The bit is automatically
set to 0 when the Write Request Flag (Wd (n+2), bit 00) turns
OFF.
