RSLogix Emulator 5000 is a software simulator for the Allen Bradley line of Logix 5000 controllers (ControlLogix®, CompactLogix®, FlexLogix®, SoftLogix5800® and DriveLogix®). The goal is to mimic the function of a PLC without the actual hardware and thus do advanced debugging. More information can be found in the AB publication LGEM5K-GR015A-EN-P.
First,you should confirm that the "input size" property of the1789-SIM module is 2.Because the input in the "I/O DATA" property interface is for the latter double word--I.Data.For the same reason, make sure you use I.Data in your program .OR, your toggle in 1789-sim module won't be reflected in the online program. Second, you have to change the emulater CPU to "run" mode when you plan to simulate your program. If you find you toggle in the 1789-SIM module can be reflected in rslogix 5000 ,but your program don't work, one possible reason is your emulater CPU is in "program" mode. 2b1af7f3a8
