Description
Batch/Groups 5 The Batch function allows the user to segment portions of data for further analysis. The Batch
function manages sections of data. Concurrent batches are now associated with a group of
pens. The pens with in each group will belong to the batch that is controlled by that group.
Batches can be controlled through the event system and batch markers are setup by the user
and are used to identify and analyse batches of data. Supports up to 6 concurrent batches.
Counters 3 User Counters can be set up and used as a part of the Events system to count an
occurrence. Other counters are available depending on hardware availability. Eg. Alarm,
Event, Digital Input, Relay Output and Pulse counters.
Modbus
Master
10 Modbus master enables the recorder to communicate with up to 32 Slave devices on both
Ethernet and RS485. The recorder itself can also act as a slave device while also being a
master.
Remote
Viewer
3 Extends the user interface of the recorder onto the desktop PC. Providing full remote control
of the unit launched from a web browser.
Email 3 Setup email accounts to send the following: When an Alarm is triggered or an Email can be
sent as a part of an Event occurring, such as: Alarms - In/Out/Ack , Totaliser – Start, Stop or
Reset, Digital Inputs – On, Off or State change, TC Burnout – on a specific Analogue Input
channel, Scheduled Events – Once, Interval, Specific days, Month End.
Pwd Net Sync 5 Password Network Synchronisation. Password can be synchronised over the network, a
recorder can be designated as a master of a password group and other recorders can be
added to that group as slaves, the master will ensure all passwords are synchronised with all
recorders in its group. Maximum number of password slaves in one group is 31.
AMS2750
Process
5 AMS2750 Process activates the Process Mode screen and the AMS2750 process
configuration menus for furnaces and sensors in accordance with AMS2750 specification,
including Thermocouple tracking.
Secure
Comms
3 Secure Comms (WSD) is a web service that can run on devices and conforms to the Devices
Profile for Web Services (DPWS). Recorder device will host web service and have server
certificate installed on it. Desktop clients will have root authority certificate of server in trusted
root certificates. Whenever client connects to WSD service SSL handshake will take place
and on successful handshaking secure communication channel will be established and data
flowing between these two end points will be encrypted.
Hardware Lock 2 Uses the password permission areas to lock access to the hardware configuration
functionality leaving some areas view only.
Extra Pens 2 4 extra pens to store and display totalised values, results of calculations, etc. Maximum is up
to 16 extra pens for the GR recorder.
Notes
1. Additional pens (“Extra Pens”) can be used to display and store the results of calculations, totalisers, variables imported via
communications, or to store values.
2. Custom Screens must be built using GR Series Screen Designer (.lay). Screens from V5 Screen Designer cannot be imported (.lyt).
3. Event markers are required to automatically reset the totalisers, for example on a periodic basis or on an external condition. (Not
necessary if the totalisers are reset manually).
4. Specification table for Sterilisation: The definition of Fo/Po is the sterilisation/pasteurisation time in minutes required to destroy a
stated number of organisms with a known z at temperature T. For example, "F18/250" represents the time in minutes required to
destroy a stated number of organisms at a temperature of 250°F (121.11°C) with a z = 18 degrees F. F values are used to
compare the sterilizing values of different processes, however, F values cannot be compared unless the z values are the same.
When temperature is not specified (for example, F = 8.6) it is understood that the temperature is 250°F (121.11°C); the subscript
O (as in the term Fo = 7.4) is used to indicate that the z = 18 degrees F and the temperature is 250°F (121.11°C).
