Installation and Operations Guide
The VLX ships with system boot code and a real-time operating code (ROC) file pre-loaded at
the factory. Diagnostic LEDs indicate the operational status of these files (see "Using VLX
diagnostic LEDs" on page 64).

ROC is the foundation of controller operations and is required for the VLX/ACM-VLX to host
DDC and automation features. An initial ROC is loaded at the factory. Periodic updates to the
ROC may be required (for example, when a new version of operator workstation software is
available). Download the ROC using the operator workstation. ROC files for a controller must
be saved in the <bactalk root>\system directory to be downloaded. ROC files typically have a
BIN extension. See Compass Help or documentation for information about downloading ROC
files and checking ROC file versions.
VLX ROC file: <bactalk root>\system\app11.bin
ACM ROC file: <Compass root>\system\app28.bin (ACM-VLX is part of the ACM ROC)

Scanning for the VLX/ACM-VLX and setting up a device
record in Device Manager
Use Device Manager to confirm that the VLX/ACM-VLX is online and to add a
device record for ongoing management. The device record stores setup
information about the VLX/ACM-VLX. An accurate device record is the key to
managing DDC, ROC files, and automation features.
A device record must exist in Device Manager for you to view and
CAUTION
change values from within Compass. You must enter a device record to set up
inputs and confirm EXP/AXM communications.
Use Device Scan to scan the network for the VLX/ACM-VLX. It is the easiest
way to add a record and ensures that the VLX/ACM-VLX is communicating.
Once a device record exists, use Device Manager to send and read data and
objects to the VLX/ACM-VLX.
See Compass Help for more information about working with Device Manager.
Confirming EXP/AXM-to-VLX/VLX-ACM communication
The reliability property of any existing EXP/AXM AI or BI indicates the status
of VLX/ACM-VLX communication with the EXP/AXM. For example, Device
201, AI-1000, reliability, indicates the status of VLX 201 or ACM-VLX 201
communication to the EXP/AXM with address 1. We recommend that you use
the reliability property associated with AI-0. Only a single reliability property
needs to be referenced. When an EXP/AXM is communicating, the reliability
property of its objects return NO_FAULT_DETECTED; otherwise, the property
returns UNRELIABLE_OTHER.
