INTRODUCTION

Sequence of Events Recorder Overview (SER-32e):
The CyTime TM Sequence of Events Recorder provides precise time-stamped event reporting for 32 channels to enable root-cause analysis and advanced system diagnostics.
Configurable event recording: Each input is individually configurable with digital filter, debounce and contact chatter functions to ensure reliable operation.
Event log: The CyTime SER records the date and time associated with all state changes to one (1) millisecond and stores up to 8192 events in non-volatile memory. Each event record contains the date/time stamp, event type, channel number and state, time quality, and unique sequence number.
Export events to Comma Separated Variable (CSV): An export button allows the user to save event data to a CSV fi le for further analysis in Excel® or other software. EPSS data log groups: Inputs can be assigned to a group for data logging purposes. If any input in a group changes state, then the states of all group members are recorded in its EPSS data log. This enables specialized reporting for mandatory tests of emergency power supply systems (EPSS) to document compliance with standards for healthcare and other critical-power facilities.
Operations counters: Operations counters are maintained for all 32 channels (inputs), with date/time of last reset. Each channel can be reset individually. Ethernet communications: Network data communications to a host system are  supported via 10/100BaseTx Ethernet using Modbus TCP and/or RESTful web service. The device also features an embedded secure web server to simplify setup, operation, fi rewire  updates and  fi le transfers. In addition, PTP (Precision Time  Protocol (IEEE 1588) or NTP(Network Time Protocol) can be used for time synchronization over  Ethernet.
Product Overview (SER-32e)
Note: The Cyber Sciences Digital Input Module is an optional addition to the CyTime TM SER-32e Sequence of Events Recorder. For more information on the SER-32e Sequence of Events Recorder, visit www.cyber-sciences.com/our-support /tech-library SER-32e User’s Guide SER-32e Reference Guide

Time synchronization (PTP). High-resolution time sync (100 µs) is supported using PTP (Precision Time Protocol, per IEEE 1588) over the Ethernet network used for data communications. (Timestamps ± 0.5 Ms) The SER-32e can be configured as the PTP
master (grandmaster clock for all other SERs and PTP-compatible devices) or a PTP slave, synchronized to a PTP grandmaster (another SER or third-party clock).
Time synchronization (other protocols). Hi-res time sync (100 µs) using ‘legacy’ protocols such as IRIG-B (unmodulated) or DCF77 is also supported. (Timestamps ± 0.5 Ms) NTP or Modbus TCP time-sync are supported, but accuracy depends on network design and is typically ± 100 ms or more.
Time-sync master. One SER can serve as a time-sync master to other devices via PTP or an RS-485 subnet. RS-485 serial protocol is either IRIG-B or DCF77 (per the input time source) or ASCII (selectable). When PTP or NTP is the time source, an SER can output IRIG-B, DCF77 or 1per10 using an optional interface (PLX-5V or PLX-24V).
Trigger output. Any input can be configured to close a high-speed output contact to trigger an associated action, such as a power meter’s capture of voltage and current waveforms coincident with an event. The trigger  occurs in the same millisecond interval
during which the event is detected, with no  filtering  applied.
Multiple Modbus masters. The SER supports data access from multiple Modbus TCP masters (up to 44 simultaneous Modbus connections). This enables integration  of multiple systems and fl edibility in how application software manages sockets.
Settings stored in non-volatile memory. All settings are stored in non- volatile fl ash memory in XML fi le format. Configuration is accomplished using a standard web browser, or by modifying the setup fi le directly (by advanced users).
Benefits for end users, system integrators and OEMs include:
Time-critical information for root-cause analysis (1 ms)
Time-stamped record of events—up to 8192 events stored in non-volatile memory.
Reliable event recording with “zero blind-time”
Event-recording engine records all events, even those occurring in rapid succession.
Advanced troubleshooting
High-speed trigger output to capture waveforms by a compatible power meter.
Simple setup using a web browser—no proprietary software
Embedded web server hosts user-friendly pages for setup and monitoring.
No maintenance required
Event data and user setup data is stored in non-volatile fl ash memory.
Easy system integration
Integrate with multiple systems via Ethernet: Modbus TCP, RESTful API and secure web interface.
Flexible time synchronization choices
PTP, IRIG-B, DCF77, NTP, Modbus TCP or SER inter-device (RS-485).
EPSS generator test-compliance reports enabled
16 data logs: when any group member changes state, all members’ states are recorded.
Easy replacement
If a unit ever needs to be replaced, settings are transferable via XML setup fi le.
Regulatory approvals to global standards
UL-Listed (UL/IEC 61010), CSA 22.2, CE, RoHS-compliant.

Introduction Digital Input Module

The Digital Input Module is an optional accessory for the CyTime™ SER-32e Sequence of Events Recorder. Each input module provides eight (8) high-speed digital inputs with millisecond time stamping.
The CyTime™ SER-32e  Sequence of Events Recorder  provides two (2) option slots  allowing its native 32 high-speed inputs  to be expanded  to a maximum of 48 inputs, all with millisecond time stamping  to enable root-cause analysis and  advanced system diagnostics.
Configurable event recording: Each input on the SER and its option modules is individually configurable with digital filter, debounce and contact chatter functions to ensure reliable operation through the SER’s web interface.
Event log: The SER records the date and time associated with all state changes to one (1) millisecond and stores up to 8192 events in non-volatile memory. Each event record contains the date/time stamp, event type, channel number and state, time quality, a unique sequence number and delta time between recorded events.
EPSS data log groups: Inputs and outputs can be assigned to user defined groups for data logging purposes. If any input or output in a group changes state, the states of all group members are recorded in its EPSS (Group) data log. This enables  specialized reporting for mandatory  tests of emergency power supply systems (EPSS) to document compliance with standards for healthcare and other critical-power facilities.
Operations counters: Operations counters are maintained for all input and output channels, with date/time of last reset. Each channel can be reset individually.
Key features: The Digital Input Module provides the ability to expand the native 32 high-speed inputs of the SER-32e to 40 or 48 inputs without the need for additional space or control power.
