3.11.3 Manual reintegration
Global reintegration of all passivated F-modules
To reintegrate all passivated F-modules / F-channels of an F-runtime group, use
the "ACK_GL" instruction:
Figure 3-20: "ACK_GL" instruction
Separate reintegration of modules (or of a group of modules)
In distributed plants, it may be required that only local reintegration is allowed (e.g.,
separate command devices on the control cabinet). To do this, interconnect the
"ACK_REI" tags of the respective F-I/O data blocks:
