=== PID Status and Auto / Manual Control ===
If the annunciator version is greater than 744, the following is available.

Under the "Annunciator Faults / Outputs Status page", which is accessed by selecting the left box of the EIM Home Page, there is a "PID" category to see the status of all loops.

On this page, the mode "Auto" or "Manual" can be selected if the access level is 'setup' or higher. In manual, the box on the right side of the page will show the manual setting, and can be selected to change the output.

On EIM versions past 2.00, the left box of the status page can be selected to change the setpoint and deadband (or all settings in 'Engineering' access level).
