FieldServer Driver – Serial

FS-8700-40

SBT-FSI

(Siemens Building Technologies – Foreign Systems Interface)

Description

This FieldServer driver can be used to poll a Siemens Fire Safety MXL or XLS system or to emulate a Siemens Fire Safety MXL or XLS system with attached modules. Either configuration supports remote monitoring as well as selected command and control functions.

 

Fieldserver Mode	Nodes	Comments
Client	1-10 (one client per physical FieldServer serial port). Depends on FieldServer model and configuration.	Only 1 client node allowed on multidrop systems
Server	99	Panel numbers from 1 to 99 may be emulated

Connection Notes

It is possible to connect a MXL/XLS device to any RS-232 or RS-485 port.  These ports simply need to be configured for MXL/XLS in the configuration file.

Using the NIM-1R or NIM-1W for MXL usage

• · Configure the NIM-1R   or NIM-1W for Foreign System Interface (FSI) by setting all of the switches in SW2 to open (or OFF).  The ports on the RPM need to be configured by the XLS panel.  Configuration can be set up for either RS-232 or RS-485, but not both together.  Connection to the RS485 port of the RPM has not been tested and is not supported

One FSI panel may be connected per FieldServer port, but multiple panels may be connected per FSI.  The following diagram illustrates two possible connection configurations.

Client Configuration File Structure

In FSI mode, the NIM-1R or RPM allows the FieldServer to gather data from up to 63 Siemens Panels connected on an MXL or XLS network.  When configured according to the default, the FieldServer will monitor two panels (1 and 2) with 8 modules (1 to 8) each.

 

Two sets of data are collected by the driver.  The first is a collection of 14 counters per panel.  Each 16-bit counter is incremented whenever the corresponding event occurs. These counters can be read to determine if a new event has been reported to the server.  The counters occur in the following order:

 

Event	Offset
Fire Alarm In	0
Fire Alarm Out	1
Fire Alarm Acknowledge	2
Trouble In	3
Trouble Out	4
Trouble Acknowledge	5
Supervisory In	6
Supervisory Out	7
Supervisory Acknowledge	8
Security Alarm In	9
Security Alarm Out	10
Security Alarm Acknowledge	11
Status In	12
Status Out	13
Test In	14
Test Out	15
Audible Silenced	16
Audible Unsilenced	17
System Reset	18

 

The second is a collection of bit maps that can be queried to determine which device has reported the event.  When an alarm from a device is received, two arrays are updated – one indicating the alarm and the other indicating that the alarm has not been acknowledged.  An alarm clear will clear the bit in the alarm array, and an alarm acknowledge will clear the bit in the un-acknowledged array.  Each of these arrays is optional.  To enable one, there must be a map descriptor in the configuration with a map descriptor message type corresponding to the array as shown in this table:

 

Array	Msg_Type
Fire Alarm	Fire
Fire Alarm Un-Acknowledged	Fire_Ack
Trouble Alarm	Trouble
Trouble Un-Acknowledged	Trouble_Ack
Supervisory Alarm	Super
Supervisory Un-Acknowledge	Super_Ack
Security Alarm	Secur
Security Alarm Un-Acknowledged	Secur_Ack
Status	Status
Test	Test

 

Server Configuration File Structure

The driver can also be used to emulate a MXL or XLS server.  Other protocol drivers could then poll remote devices and access the local MXL or XLS server data to set or clear events.  In this configuration an existing Siemens Fire Safety MXL or XLS panel could be replaced with an emulation.  Existing clients could poll the emulation driver on the FieldServer to get the same data as from a conventional MXL or XLS server.

 

Up to 100 panels can be emulated with the driver. Each panel has to be on a unique port and have a unique node id assigned. A map descriptor has to be defined for each type of remote device. The following types can be used:
