6.1 Monitoring SENSOR Interface Module Software
Monitoring SENSOR Interface Module Software (monitoring module) may be deployed either at a dedicated work station or at a server shared with CDWS core. Monitoring module ensures interfacing TMD by a proprietary protocol. Transport layer: TCP/IP; protocol: JSON.
Sensor Status Recorder (SSR) by SENSOR Group of Companies serves as a terminating monitoring device (TMD). The recorder either receives data from current-loop interfaced sensors or processes four discrete channels (various versions of recorder).
The monitoring module supports simultaneous work with various versions of multiple recorders and transmits gathered data to CDWS core. The number of connected TMDs may be limited by link carrier capacity only.
SSR sensor status recorders are configured and set up according to Monitoring Module and Terminating Monitoring Device Configurator manual.
Figure 2.1 – Monitoring module configurator
Set the monitoring module configurator as follows to ensure its connection to (CDWS) core:
Other settings shall be set according to Monitoring Module and Terminating Monitoring Device Configurator. Data gathered by the monitoring module are accessible through a table interface (see Figure 2.2) and on the map (see Figure 2.3) at dispatcher’s work station.

The map shows sensor name (designation), sensor data in physical units, sensor status and last update time.

In case of loss of connection to the CDWS core the monitoring module stores data received by TMDs and transmits received data history to CDWS core by core request. The monitoring module stores historical data within a month, at least.
The monitoring module implies continuous system operation within the entire service life.
A core may be connected to multiple monitoring modules divided by application or object principle.
The monitoring module allows parallel data receipt from numerous TMDs. The number of connected TMDs may be limited by link carrier capacity only.
The monitoring module transmits terminating equipment configurations to the CDWS core. With database setting the CDWS core defines monitoring module exchange cycle based on terminating equipment configuration and initiates the exchange.
The monitoring module transmits event messages (crossing of TMD-configured thresholds) to CDWS core in advance of the next data exchange session.
