Off-line Simulation
Opens a compiled project (*.xob) in off-line simulator mode.
Pass-through mode
The pass-through mode allows serial communications from the PC to the PLC, though the HMI. This can eliminate the
need to disconnect the PLC from the HMI when it is necessary to configure the HMI.
To use the serial pass-through mode:
1. Select COM port. In the serial pass-through mode, data coming in on one serial port on the HMI is re-
transmitted out another serial port to the PLC.
2. HMI/IP: If the HMI has an Ethernet port, Project Manager can query the HMI to get its communication
parameters through the Ethernet port. Specify the IP Address of the HMI that is to be used in pass-through
mode and click Get HMI Communication Parameters to read the current communication settings for the
HMI (if the HMI is connected directly to the PC’s Ethernet port, you must use a crossover Ethernet cable).
3. HMI work mode: Indicates the current mode of the HMI. After the communication parameters have been
received, the mode will be either Normal (HMI set to communicate with PLC) or Pass-through (HMI is in
pass-through mode).
4. Source COM Port (PC -> HMI): Set COM settings for the HMI COM port that will be connected to the PC.
