Environmental control system
Using the ECS
HP recommends connecting the HP POD to your facility BMS, communicating through Ethernet cable
connected to the external communications box. For more information, see Configuring the ECS (on page
32).
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.
The ECS offers:
• A supported communication interface that can monitor and control certain HP POD components
remotely
• Immediate notification of all supported alarm messages
By connecting your HP POD to a BMS system, you can monitor:
• Cold and hot aisle temperatures
• Supply and return water temperatures
• Chilled water flow rate entering the HP POD
• Notification of supported alarms
For additional points that can be monitored, see the I/O controls points list in the Appendix.
NOTE: If your site does not have a BMS, then HP POD ECS data can be sent to and viewed
from a set IP address, communicating through an Ethernet cable connected to the external
communications box.
