WLM2-SIP-MODULE
INTRODUCTION
With the increasing use of Building (Energy) Management Systems, OJ
Electronics Ltd has developed, in partnership with Synapsys Solutions, the
WLM2-SIP-MODULE (ModBus/vIQ) interface.
This interface has been designed for simple plug and play connection
between the Trend® front end systems and the WLM2-1FS BMS Waterline
Control System. The primary aim of the development was to help reduce
engineering time and cost, and to meet the demand for more information
and better energy control.
Used in conjunction with a Trend® BMS, it can help ensure a building complies with latest Part L2 Building
regulations.

The WLM2-SIP-MODULE product has been designed to easily interface
between the WLM2-1FS/B, and associated networked WLM2-1BA
Masters & add-on modules, to a Trend B(e)MS (Building (energy)
Management System). This allows up to 31* heating manifolds to be
monitored and controlled remotely.
DESIGN AND FUNCTION
The product displays information recorded by ModBus slaves
communicating via ModBus. It exploits their data capability, by
retrieving, logging (‘Map points’ page) and presenting (‘vIQ’ page)
selected types of data, e.g. Temperature, set-point, pump and boiler
demands in real time. This information allows Building managers to
monitor, record and adjust any aspect of the buildings heating or cooling
