ALTUS Nexto Series User Manual

5. CONFIGURATION
ATTENTION
REFRESH_OUTPUT function does not support inputs that have been mapped to symbolic
variables. For proper operation it is necessary that the input is mapped to a variable within
the memory direct representation of input variables (%Q).
ATTENTION
The REFRESH_OUTPUT function updates only the direct variables %Q that are declared
in the "Bus: I/O Mapping" tab of the module addressed in the respective rack/slot of the
function. In the case of communication modules/interfaces (MODBUS, Profibus, etc.), the
update does not include the direct variables of the device mappings.
Figure 149: Block for Output Updating
Input parameters Type Description
byRackNumber BYTE Rack number.

nected.

bySlotNumber: BYTE;
END_VAR
//INPUTS:
byRackNumber := 0;
bySlotNumber := 10;
//FUNCTION:
//Function call.
Info := REFRESH_OUTPUT (byRackNumber, bySlotNumber);
//Variable "Info" receives possible function errors.
