Implicit exchange objects
Implicit exchange objects associated with the analog function
At a Glance
Channel values
These are objects used for programming and performing diagnostics of analog modules These objects are exchanged automatically on each task cycle in which the module channels are configured.
Values of analog channels, applicable to all modules.

Function
Value of input channel in analog input module.
Value of output channel in analog output module.
Example: Word %IW105.3 always contains the present value on input 3 of the module in position 5 in address 1 rack.
Error bit objects Error bit objects, applicable to all modules.
Address (1)

R
Meaning
When it is on 1, this indicates that the i input channel of the module at the @module address is faulty.
%[email protected]
When it is on 1, this indicates that the module at the @module address is faulty.
Key: @module = module address: l l xy for racked modules,
\p2c\m for remote modules.
