Rotork Master Station Features continued
Redundancy
Standard: A single Master Station consists of a Master Station rack into which the following units can be connected:
Display module; PSU module (P4740); CPU module (P4710)
Up to four total AIMs:
Field Network: Pakscan Classic (P4720)
Field Network: Modbus RTU (P4724)
Host Serial AIM (P4727)
In a single unit all of these modules will be arranged on the left side of the Master Station rack.
Leaving the right side free.
The single Master Station has redundant host connections to the CPU module and the field networks
can be redundant loops.
Option: For full redundancy, the hot standby Master Station contains a primary (side A, left) set of modules as described
above and identical redundant standby (side B, right) set of modules. The primary side ensures the standby side is
continually updated with the status of all the connected FCUs such that it can take over control of the field
network in the event of a failure of the primary module or if the request to change masters is received. The
standby will also take over the communications to the host network.
Change over time is less that 500 ms for the field network communications.
User interface
Standard: No specialist software required to configure system.
Can be configured fully via Local touch screen Interface or built in web pages.
Each Master Station contains at least 1 local touch screen interface – 2 in the case of a hot standby or dual unit.
• Size: 7.0” • Resolution: 1024 x RGB x 600
The local and web based interfaces have an identical structure, creating a consistent user interface across
both platforms. The user interface is focused towards quick device setup, interrogation and issue resolution.
Both interfaces enable:
Viewing of status, alarms and settings for the Master Station, field network, host network and FCUs.
Configuration of settings for the Master Station, field network, host network and FCUs.
Viewing of host communication logs.
Viewing of Master Station datalogger and FCU event logs.
In addition, the web interface enables:
Saving of Host analyser and Master Station datalogger files.
Upgrading the Master Station software.
Saving of Master Station alarm logs.
