Note If the setting direction of the Temperature Control Unit is set to the C200H PC
and the C200H is in program mode, all word data will be 0. Therefore, if the
C200H in program mode has been set to continuous control, the Temperature
Control Unit executes temperature control when the C200H stops operating,
judging that the SP has been changed to 0 C. To prevent this, set SW2-2 of the
Temperature Control Unit to OFF (i.e., the setting direction is set to the Data Set-
ting Console) before the C200H stops operating and reset SW2-2 after the
C200H restarts.
Data contents
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 platinum resistance thermometer data, the least
significant digit is 0.1. The most significant digit is F for minus (–).
Outputs the Loop 1 and Loop 2 SP (set point) as 4-digit BCD
data. For platinum resistance thermometer data, the least data For platinum resistance thermometer data the least
significant digit is 0.1. The most significant digit is F for minus (–).
Outputs the bank number currently executed for Loop 1 and Loop
2 as 1-digit BCD data.
Not used. Each bit is set to 0.
Outputs the ON/OFF status of SW2-2 (setting direction).
0: Data Setting Console
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.
Bit set to 1 when the detected heater current
exceeds 55.0 A.
Not used. Each bit is set to 0.
Bit 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).
Bit set to 1 if the detected heater current drops
below the set heater burnout current value. (HB:
heater burnout)
Bit set to 1 when the temperature enters the set
alarm range (Refer to page 23). l (R f t
