Word DescriptionBits
11
0 Loop4 Enable
•0 = Loop 4 disabled.
•1 = Loop 4 enabled.
1 Loop4 Auto/Manual Mode Select  (controlled by bit 1 of word 14 of the dynamic block)
•0 = Loop 4 is in the manual mode  the manual output value (from word 17, dynamic block) is used as the CV value.
•1 = Loop 4 is in the automatic mode  the PID algorithm generates the CV value.
2 Loop4 Open Circuit
•0 = Loop4 thermocouple circuit is closed (connection OK).
•1 = .Loop4 thermocouple circuit is open (connection broken).
3 Loop4 Parameters valid
•0 = Power has been interrupted since valid parameters for loop 4 have been blocktransferred.
•1 = Valid parameters for loop 4 have been blocktransferred since last loss of power .
4 Loop4 Calibration Fault
•0 = Loop4 calibration is OK.
•1 = Loop4 cannot operate with as calibrated.
5 Loop4 SetPoint Select  (controlled by bit 2 of word 14 of the dynamic block)
•0 = Select the standbytemperature setpoint value from word 15 of the dynamic block.
•1 = Select the runtemperature setpoint value from word 16 of the dynamic block.
6 Loop4 Parameter Value Error
•0 = Loop4 parameter values OK.
•1 = Loop4 parameter value error.
7 Loop4 AutoTuning Complete
•0 = Loop4 autotuning is not complete.
•1 = Loop4 autotuning is complete.
8 Reserved.
9 Reserved.
10 Loop4 Thermal Runaway  (set in words 22 and 23 of the configuration block)
•0 = Loop4 is operating within thermal runaway limit..
•1 = Loop4 has exceeded the thermal runaway limit. and the CV value has been forced..
11 Loop4 High CV Limit  (set in word 7 of the configuration block)
•0 = Loop4 CV value is below the high CV limit.
•1 = Loop4 CV value is at the high CV limit.
12 Loop4 Low CV Limit  (set in word 8 of the configuration block)
•0 = Loop4 CV value is above the low CV limit.
•1 = Loop4 CV value is at the low CV limit.
