Product Overview (SER-32e)
Note: The Cyber Sciences Digital Input Module is an optional addition to the CyTimeTM 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

1–INTRODUCTION
Sequence of Events Recorder Overview (SER-32e): The CyTimeTM 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 file 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, firmware updates and file transfers. In addition, PTP (Precision Time Protocol (IEEE 1588) or NTP (Network Time Protocol) can be used for time synchronization over Ethernet.

INSTRUCTION BULLETIN–User’s Guide Digital Input Module eXM-DI-08
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 flexibility in how application software manages sockets.
Settings stored in non-volatile memory. All settings are stored in non-volatile flash memory in XML file format. Configuration is accomplished using a standard web browser, or by modifying the setup file directly (by advanced users).

Benefits SER-32e

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 flash 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 file.
Regulatory approvals to global standards UL-Listed (UL/IEC 61010), CSA 22.2, CE, RoHS-compliant.

Filter

Filter time is the minimum time that an input must remain in its new state before it is recorded as an event. This helps eliminate false events due to noise, transients, etc.

0 to 65535 ms

20ms

Debounce Chatter

Debounce time is the period that event processing is suspended for a given input after an event has been recorded. This prevents recording multiple events for a single state change.
Chatter count is the maximum number of events recorded for a given input per minute. If the number of events per minute exceeds the setpoint, the input will be disabled for further event processing until the number of events per minute drops below the setpoint. This prevents recording an excessive number of events due to a faulty input. Events are also generated to indicate the time event processing was suspended / resumed.

0 to 65535 ms
0 to 255 (0 = Disabled)

20ms 0 (disabled)

Off Text and On Text Customized label to describe an input’s “off” state and “on” state

UTF-8, 16-char.

On / Off

High-speed Trigger Output

Any input can be configured to close the “Trigger Out” contact on status change. This is typically used to trigger a compatible power meter to capture current and voltage waveforms coincident with an event to aid analysis and troubleshooting.

Enabled or Disabled

Disabled

Inverted

Any input can be designated as “inverted” and status reported opposite of its sensed state

Normal or Inverted

Normal

Group Assignment (for Data Logs)

Each input can be assigned to a data log group for reporting purposes

None, or Group 01 to Group 16

None

Only the following special characters are available: ! @ # $ & * ( ) _ – + = { } [ ] ; . ~ ` ‘ Setting this time too low (e.g., < 5 ms) can cause unwanted events to be recorded; setting too high (e.g., > 100 ms) can result in missed events.
