Hi All

Some time ago i asked for some help regarding the SLC505 DEM instruction. Now a new question has come up - can the 1747-SDN slot number be altered dynamicly or do i have to program 2 DEM instructions with seperate ctrl blocks? The reason i ask is, that i have 2 devicenets on the same processor, and i want to access both from the same HMI.
 
It's OK to change the class/instance/attribute or destination node number, but I would recommend using separate DEM instructions for separate 1747-SDN modules.
