Product Introduction
The Sequence 2002NZ10801C of Events Recorder (SOE) is a form of MODCELL Multiloop Processor which scans up to 29 digital inputs every millisecond for state transition, with debounce filter capability. Transitions (events) are timestamped and stored in a local queue, for monitoring and logging the order in which events such as motor trips and alarms occur. The event queue will hold up to 1024 entries, and can be read via the Status Page of the Application Builder software.

Product Details
The base unit is supplied on a mounting plate which fits standard EIA racks or panels. Field terminations use groups of pluggable, screw-down termination blocks for easy signal wiring, and power supply connections are separated from field signal wiring. The unit contains an on-board ac or dc power supply, a high-speed CPU based on a Motorola 68302 microprocessor, and associated firmware to support the discrete inputs, communications and event functions. The optional Memory Module provides redundant, removable non-volatile RAM which backs up the database and, if left on the unit during operation, current process data.
Digital inputs for the SOE identity can be isolated (2.5 to 28V dc or 4 to 16Vdc) or non-isolated with TTL power, or a combination. Communications to the Application Builder software is accomplished via the Instrument Communications Network. The event queue is read by the software and logged in the Alarm/Event Summary.
Sequence of Events Recorder with 1 ms accuracy
Supports up to 29 single point, individually isolated discrete inputs per unit
Local or global time synchronization
Common hardware platform with MODCELL process control system
The Sequence of Events firmware includes an Omega Clock Block that either monitors a timestamp signal which is broadcast every second, or transmits a timestamp signal every second. Time synchronization between multiple SOE MODCELLs is via RS-485, 2-wire communications. Up to 32 MODCELLs configured as SOE Recorders can be installed on an RS-485 network without repeaters.
If the system requires only the devices on the local network to be synchronized, one of the MODCELL Sequence of Events Recorders on the network can transmit the timestamp. An RS-485, 2-wire serial communications module is installed on each unit, with one unit acting as the Transmit master and the others set to Receive. Recommended transmission rate is 38.4K baud.
If the system requires synchronization to a global timestamp, a Kinemetrics/Truetime Omega Synchronized Clock Unit must be installed. This unit monitors the OMEGA navigation system which has eight transmitting stations around the world. It transmits via an RS-232 port, and an RS-232/RS-485 convertor is also required. The time signal is transmitted to the MODCELL units via RS-485.
