Environmental control system

Environmental control system overview

The ECS developed for the HP water-cooled POD is a stand-alone control system that requires no external connections with an external site system, BMS, public or private Internet sites, cloud, or wireless system to properly control the POD operation.

The ECS includes Modbus TCP/IP connections through which a variety of data can be retrieved. These capabilities enable you to connect, at your expense, with the stand-alone ECS system to monitor the operating parameters of the POD. 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 ensure 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 20c 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 39)."

The HP POD 20c ECS is a Windows-based system with the following features:

•Intel Core Duo processor

•15-inch touchscreen

•512 MB RAM

•80 GB hard drive

•24 V DC power supply

•One serial port

•Four USB ports

•1x10/100 BASE-T and 1x10/100/1000 BASE-T Ethernet connectors

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 20c and a BMS system.

The ECS provides the following:

•A supported communication interface that can monitor and control certain HP POD 20c components remotely

•Immediate notification of all supported alarm messages
