should match integer point N50:11.
0 = System is in LOCAL control mode
Heater 1 = System is in REMOTE control mode
output
This setting is adjusted in the control access menu,
through the operator interface touch screen.
0 = System disabled
Heater
output
1 = System enabled
0 = Not operating
Heater
output
1 = Operating
0 = Outlet temperature is not within the process
deviation setting
Heater
output
1 = Outlet temperature is within the process deviation
setting
0 = No system fault detected
Heater
output
1 = System fault detected
The value provided will indicate which safety device has
