Local Display Unit (LDU™)
The CMR LDU™ Local Display Unit has been developed to perform two main functions: alarm reporting and responsibility transfer.
These features are mandatory to operate in Unattended Machinery Spaces (UMS) for marine environments.
The Local Display Unit is an electronic unit intended to display parameters for unattended marine applications in the machine room to display alarm information and notify a request for responsibility transfer.
The LDU™ communicates with the supervision software through an RS485/RS422 type network architecture using the MODBUS RTU communication protocol.
The communication interface can be configured in RS232 to perform a point-to-point connection and is mechanically designed with a small form factor to take up minimum space in a bulkhead or electrical cabinet housing.
In normal operation, alarms are grouped to be sent in a compact form to the various facilities (such as mess room, meeting room, cabins) and especially for the on-duty staff cabin
Optimized to operate with the CLARINUX™ alarm monitoring and supervision software, it is also easily possible to interface the LDU™ with other alarm monitoring systems.
