PROGRAM
I/O scanning (Controller and expansion Racks[C50 CPU only]) is performed, but
function blocks are not executed, and all outputs (digital and analog) are set to OFF.
(See Note 1.)
Monitoring of Diagnostics (Controller and Expander Racks)
Detection of I/O Modules
Other functions permitted:
function blocks are not executed, and all outputs (digital and analog) are set to OFF.

Indications of Forces at Status LEDs at I/O modules
OFFLINE
IO scanning (Controller and Expander Racks) is performed, but function blocks are
not executed, and all outputs (digital and analog) are Frozen (see Note 2) at the
states they were in when the OFFLINE mode was selected.
Monitoring of Diagnostics (local and expanded racks)
Detection of I/O Modules
Other functions permitted:
not executed, and all outputs (digital and analog) are Frozen (see Note 2) at the
states they were in when the OFFLINE mode was selected.

Note 1: The Off state of the module outputs are defined as:
•
Digital output - low state
•
Time proportional Output (TPO) : 0% duty cycle
•
TPSC Outputs: Both Fwd and Rev are Off.
•
Analog output: 0.0 mA
Note 2: The Frozen states of module outputs are defined as:
•
Digital output: same state as previous (last active state)
•
Time Proportional Output (TPO): Same duty cycle as in last active state
•
TPSC Outputs: digital outputs are Off to freeze the motor position.
•
Analog output: same current as previous (last active current level)
