Force Mode

@Updated D1

WARNING
Unintended equipment operation Before using Force mode, ensure that forcing parameters or energizing loads will not result in unsafe conditions. Failure to follow these instructions can result in death, serious injury, or equipment damage.

NOTE: Once Force mode is activated, commands from the digital tools take priority over commands from the PLC or Local until you exit Force mode.

Once the TeSys island is in the operational state, Force mode can be activated and deactivated using the OMT or TeSys island DTM.

Using Force Mode to Simulate Commands from the PLC

Force mode allows you to test the logic of any TeSys avatar by simulating receipt of commands from the PLC.

Simulating a PLC Command with Force Mode

Step	Action
1	Access Force mode: To access Force mode using the OMT, navigate to the Avatar View panel and select an avatar. Click I/O View. The logic diagram for the selected avatar is displayed. To access Force mode using the TeSys island DTM, click the Diagnostics tab and select an avatar from Avatars. Click Status. The logic diagram for the avatar is displayed.
2	To simulate receipt of a PLC command: To simulate an Open command from the PLC, click Force 0. To simulate a Close command from the PLC, click Force 1.
3	When finished, exit Force mode. See Exiting Force Mode.

Using Force Mode to Simulate Status Updates to the PLC

Force mode also allows you to simulate transmission of avatar status updates from the island to the PLC.

Simulating Avatar Status Updates from the Island to the PLC

Step	Action
1	Access Force mode from the OMT or TeSys island DTM as described in Simulating a PLC Command with Force Mode.
2	To simulate avatar status: Click Force 0 to simulate transmission of contactor Closed status to the PLC. Click Force 1 to simulate transmission of contactor Open status to the PLC.
3	When finished, exit Force mode. See Exiting Force Mode.

Using Force Mode to Simulate Status Changes of the Digital I/O Module Inputs and Outputs

Force mode also allows you to simulate status changes of the digital I/O module inputs and outputs. When force mode has not been applied, the status box is gray and shows Not Applied.

Status Box

Force Command	Input From PLC	Status To PLC
Force 0	Off	Off
Force 1	On	On

Step	Action
1	Access Force mode from the OMT or TeSys island DTM as described in Simulating a PLC Command with Force Mode.
2	To simulate I/O status, under From PLC: Click Force 0 to turn Off the digital output. Click Force 1 to Close the digital output status.
2	Under To PLC: Click Force 0 to Close the digital input status. Click Force 1 to Open the digital input status.

Exiting Force Mode

To exit Force mode, perform the steps in the following table:

Exiting Force Mode

Step	Action
1	To exit Force mode using the TeSys island DTM, in the Diagnostics tab, click Exit next to Force Mode, and then confirm you wish to exit.
2	To exit Force mode from the OMT:
	Click the Diagnostics panel.
	Click the Exit force mode button. A hazard message pop-up window appears. Click Yes to confirm that you want to exit Force mode. The status banner at the top indicates that the system is no longer in Force mode.
