Data contents
Write = 01 Read = 00
The data bit sets the Loop Number to which the
read or write operation applies.
Loop 1 = 01, Loop 2 = 10
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.
Sets the command code (Refer to page 41) for the
read or write operation as 2-digit BCD data.
Set the SP for a write operation as 4-digit BCD data. For data
including 0.1 units, the least significant digit represents 0.1. Set
the most significant digit to F for minus (–). The write operation
commences on the ON rising-edge of the write request flag (Wd
(n+2), bit 00 ).
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 (default value = 1). e ous a ue (de au a ue
Not used. Set to 0.
Bit set to 0 during temperature control of Loop 1 and set to 1
when the control stop is executed. This bit will not be available
under the program mode with SW203-5 set to ON (same as the
control stop).
Not used. Set to 0.
Bit set to 0 during temperature control of Loop 2 and set to 1
when the control stop is executed. This bit will not be available
under the program mode with SW203-5 set to ON (same as the
control stop).
Not used. Set each bit to 0.
Turn this bit ON when writing the write data set with Wd (n+1)
with the commands set to Wd (n).
Turn this bit OFF after the write complete flag (Wd (n+6), bit 08)
turns ON.
Outputs the Loop 1 and Loop 2 PV (process value) as 4-digit
BCD data. For platinum resistance thermometer data, the least BCD data. For latinum resistance thermometer data, the least
significant digit is 0.1. Set the most significant digit to F for minus
(–).
Outputs the data read with the commands set with Wd (n). For
data including 0.1 Units, the least significant digit represents 0.1.
Set the most significant digit to F for minus (–).
Not used. Each bit is set to 0.
Bit set to 1 when the write data exceeds the set permissible
range. The bit is automatically set to 0 on the OFF falling-edge of
the write request flag (Wd (n+2), bit 00).
Not used. Each bit is set to 0.
Bit set to 1 when the write operation due to the instructions set
with Wd (n) ends normally. The bit is automatically set to 0 on the
OFF falling-edge of the write request flag (Wd (n+2), bit 00).
