5.22 MX, data multiplexer
This function block is available for easy800-SWD from device version 01 and
for easy800 standard devices from device version 07.
The data multiplexer function block allows you to select a value from eight
input values MX..I1 to MX..I8 as if using a mode selector switch.
The function block provides this value after transferring it to its output
MX..QV.
A easy800 device allows the use of up to 32 data multiplexers.
The function block is enabled via the coil in the circuit diagram and its contact
is then queried as an error output.
Contacts and Coils
When the enable coil MX..EN is set to 1, it switches the selected input Ix to
output QV. This switch operation is retained for as long as MX..EN is 1.
When the MX..EN state changes from 1 to 0, output QV is reset to 0.
Example
Figure 158:Wiring the enable coil
Its coil MX01EN is directly connected to the device terminal I05.
Figure 159:Wiring of the function block contact MX01E1
The function block contact MX01E1 (fault message) is associated with the
marker M12.
