GE Vernova iSTAT M365 data center application

Software

The iSTAT M365 utilizes QDSP setup software to allow for easy initial meter setup, configuration and data visualization.

Easy setup and data visualization using QSDP software

Time Sync

The iSTAT M365 support multiple types of time synchronization to ensure accuracy and synchronization of various measurements and events to meet standards.

GE Vernova Reason RT43x GNSS clocks are recommended to provide accurate time synchronization.

GPS time synchronization (PPS and NMEA)
Time Sync unit
  • 1pps and serial RS232 communication with NMEA 0183 sentence support
  • The interface is designed as 5 pole pluggable terminal (+5V for receiver supply, 1pps input and standard RS232 communication interface)
IRIG time code B (IRIG-B)
  • Unmodulated (DC 5V level shift) and modulated (1 kHz) serial coded format with support for 1pps, day of year, current year and straight seconds of day as described in standard IRIG-200-04. GE Vernova Reason RT43x GNSS clocks recommended for time synchronization
  • Supported serial time code formats are IRIG-B007 and IRIG-B127 Interface for modulated IRIG-B is designed as BNC-F terminal with 600 Ohm input impedance
  • Interface for unmodulated IRIG-B is designed as pluggable terminal
Network time protocol (NTP)
  • Synchronization via Ethernet requires access to a NTP server

Note: NTP can usually maintain time to within tens of milliseconds over the public Internet, but the accuracy depends on infrastructure properties - asymmetry in outgoing and incoming communication delay affects systematic bias. It is recommended that dedicated network rather than public network is used for Synchronization purposes.

Communications

The iSTAT M365 supports various communications connections and protocols for easy integration. It is equipped with standard communication port COM1 (Ethernet & USB) and an auxiliary communication port COM2 (RS232/RS485).
