Environmental control system

Environmental control system overview

The ECS is a stand-alone control system developed for the HP POD 240e NA. The ECS does not require

external connections with an external site system, BMS, public or private internet site, cloud, or wireless

system to control the POD operation properly.

The ECS is designed to use Modbus TCP/IP connections to retrieve a variety of data. These capabilities

connect to the stand alone ECS system to monitor the operating parameters of the POD at your expense. It is

your responsibility (or your representative's or agent's responsibility) to integrate this communication

capability into any existing BMS or monitoring system.

CAUTION: To be sure that alarm conditions can be identified and resolved, HP recommends that

you remotely monitor all alarm conditions. Failure to monitor the alarm conditions can cause

delays in appropriate action during an alarm condition.

Using the ECS

HP recommends connecting the HP POD 240e NA to your facility BMS and establishing communication

through the Ethernet cable connected to the external communications box. For more information, see

"Configuring the ECS (on page 38)."

The HP POD 240e NA ECS is a Microsoft Windows-based system.

The standard ECS protocol, Modbus TCP/IP, is a data communication protocol for building automation and

control networks. Connecting across different protocols might require additional engineering labor and

coordination between your in-house control manufacturer and HP. It is your responsibility to make the

connection between the HP POD 240e NA and a BMS system.

The ECS provides the following:

• A supported communication interface that can remotely monitor and control certain HP POD 240e NA

components.

• Immediate notification of all supported alarm messages.

By connecting your HP POD 240e NA to a BMS system, you can monitor the various parameters and alarms.

For more information, see "Navigating the ECS interface (on page 42)." The complete list of parameters and

alarms that can be monitored will be discussed with your facilities personnel.

IMPORTANT: If your site does not have a BMS, HP POD 240e NA ECS data can be sent to and

viewed from a set of IP addresses on a host computer. The ECS communicates through an Ethernet

cable connected to the demarcation box (on page 67).
