5.Configuring the FieldServer as a Gamewell Serial Driver Server
The Gamewell Serial Driver provides limited server functionality. This has been developed to allows for automated testing and Quality Assurance. It is not supported or documented however, at a client’s request it can be extended & documented (typically at an additional cost.)
6.Advanced Topics
6.1Driver Limitations & Exclusions
The driver does not support scaling when data is stored in a data array. The keywords
‘Data_Array_Low_Scale, Data_Array_High_Scale, Device_Low_Scale, Device_High_Scale’
have no meaning for this driver. The reason for this is that the values stored by the driver have specific meanings based on parsing the message. Scaling is only applicable in drivers which read and write values from the remote device.
6.2Data Types
Messages contain Status and Action information. The status information indicated the state of a device / circuit / panel. The action information describe the event that generated the message.
By specifying one of the following Data_Types you can filter the incoming messages so that on certain types of messages update certain data arrays. For example, if you are only interested in storing data from messages that report an alarm then set the Data_Tupe of that map descriptor to ‘Alarms’. If you don’t care about the particular state then use the Data_Type of ‘Any’. The driver will set the values of the array elements
Data_Type | Status | Note # |
Any |
| 1 |
Alarms | Status:ALARM | 2 |
Faults | Status:FAULT | 2 |
Events | Status:EVENT | 2 |
Bus | Status:BUS | 2 |
Comm | Status:COMM | 2 |
Control | Status:CONTROL | 2 |
Ack | Status:ACK | 2 |
Signal Silence | Status:SIG SIL | 2 |
Troubles | Status:FAULT | 2 |
Supervisories | Status:EVENT and Action contains "Supv. Event in" | 2 |
