1: C200H PC
Outputs the ON/OFF status of SW2-1 (switching memory
contents).
0: Fixed
1: Normal
Not used. Set to 0.
Bit set to 1 if the sensor is not connected, a sensor
wire is broken, or the input data exceeds the
operational temperature range.
Not used. Each bit is set to 0.
ON (set to 1) for Manual Output Mode.
ON (set to 1) during operation.
Not used. Each bit is set to 0.
Bit set to 1 when the control output (transistor or
voltage output) is ON.
Bit set to 1 during auto-tuning (AT).
Not used. Set to 0.
Bit set to 1 when the value enters the set alarm
range. (Refer to page 23.)

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 40) for the
read or write operation as 2-digit BCD data.
