Word DescriptionBits
20
0 Loop7 Enable
•0 = Loop 7 disabled.
•1 = Loop 7 enabled.
1 Loop7 Auto/Manual Mode Select  (controlled by bit 1 of word 26 of the dynamic block)
•0 = Loop 7 is in the manual mode  the manual output value (from word 29, dynamic block) is used as the CV value.
•1 = Loop 7 is in the automatic mode  the PID algorithm generates the CV value.
2 Loop7 Open Circuit
•0 = Loop7 thermocouple circuit is closed (connection OK).
•1 = .Loop7 thermocouple circuit is open (connection broken).
3 Loop7 Parameters valid
•0 = Power has been interrupted since valid parameters for loop 7 have been blocktransferred.
•1 = Valid parameters for loop 7 have been blocktransferred since last loss of power .
4 Loop7 Calibration Fault
•0 = Loop7 calibration is OK.
•1 = Loop7 cannot operate with as calibrated.
5 Loop7 SetPoint Select  (controlled by bit 2 of word 26 of the dynamic block)
•0 = Select the standbytemperature setpoint value from word 27 of the dynamic block.
•1 = Select the runtemperature setpoint value from word 28 of the dynamic block.
6 Loop7 Parameter Value Error
•0 = Loop7 parameter values OK.
•1 = Loop7 parameter value error.
7 Loop7 AutoTuning Complete
•0 = Loop7 autotuning is not complete.
•1 = Loop7 autotuning is complete.
8 Reserved.
9 Reserved.
10 Loop7 Thermal Runaway  (set in words 22 and 23 of the configuration block)
•0 = Loop7 is operating within thermal runaway limit..
•1 = Loop7 has exceeded the thermal runaway limit. and the CV value has been forced..
11 Loop7 High CV Limit  (set in word 7 of the configuration block)
•0 = Loop7 CV value is below the high CV limit.
•1 = Loop7 CV value is at the high CV limit.
12 Loop7 Low CV Limit  (set in word 8 of the configuration block)
•0 = Loop7 CV value is above the low CV limit.
•1 = Loop7 CV value is at the low CV limit.
