Word Description
Bits
23
0
LoopĆ8 Enable
•
0 = Loop 8 disabled.
•
1 = Loop 8 enabled.
1
LoopĆ8 Auto/Manual Mode Select Ċ (controlled by bit 1 of word 30 of the dynamic block)
•
0 = Loop 8 is in the manual mode Ċ the manual output value (from word 33, dynamic block) is used as the CV value.
•
1 = Loop 8 is in the automatic mode Ċ the PID algorithm generates the CV value.
2
LoopĆ8 Open Circuit
•
0 = LoopĆ8 thermocouple circuit is closed (connection OK).
•
1 = .LoopĆ8 thermocouple circuit is open (connection broken).
3
LoopĆ8 Parameters valid
•
0 = Power has been interrupted since valid parameters for loop 8 have been blockĆtransferred.
•
1 = Valid parameters for loop 8 have been blockĆtransferred since last loss of power .
4
LoopĆ8 Calibration Fault
•
0 = LoopĆ8 calibration is OK.
•
1 = LoopĆ8 cannot operate with as calibrated.
5
LoopĆ8 SetĆPoint Select Ċ (controlled by bit 2 of word 30 of the dynamic block)
•
0 = Select the standbyĆtemperature setĆpoint value from word 31 of the dynamic block.
•
1 = Select the runĆtemperature setĆpoint value from word 32 of the dynamic block.
6
LoopĆ8 Parameter Value Error
•
0 = LoopĆ8 parameter values OK.
•
1 = LoopĆ8 parameter value error.
7
LoopĆ8 AutoĆTuning Complete
•
0 = LoopĆ8 autoĆtuning is not complete.
•
1 = LoopĆ8 autoĆtuning is complete.
8
Reserved.
9
Reserved.
10
LoopĆ8 Thermal Runaway Ċ (set in words 22 and 23 of the configuration block)
•
0 = LoopĆ8 is operating within thermal runaway limit..
•
1 = LoopĆ8 has exceeded the thermal runaway limit. and the CV value has been forced..
11
LoopĆ8 High CV Limit Ċ (set in word 7 of the configuration block)
•
0 = LoopĆ8 CV value is below the high CV limit.
•
1 = LoopĆ8 CV value is at the high CV limit.
12
LoopĆ8 Low CV Limit Ċ (set in word 8 of the configuration block)
•
0 = LoopĆ8 CV value is above the low CV limit.
•
1 = LoopĆ8 CV value is at the low CV limit.
