MX4428 MXP Engineering / Technical Manual

 

MXP Diagnostic Terminal

SPA

Adds all points to the list of points to be monitored.

SP nnn

Adds point nnn to list.

P nnn

Adds point nnn to list

SP nnn mmm Adds points nnn to mmm.

P nnn mmm

Adds points nnn to mmm.

CPA

Clears all points from monitoring list.

CP nnn

Clears point nnn from list.

CP nnn mmm Clears points nnn to mmm from list.

SP

Displays all points selected to be monitored (i.e. in monitoring list)

The values nnn and mmm must be in the range of 1-200.

Note that if more than about 50 points are monitored at once, the serial output may not be fast enough and some data may be discarded.

If it is not required to monitor any points be sure to deselect all points (CPA). Monitoring a large number of points may have a detrimental effect on processing time. Therefore enter the CPA command before disconnecting the laptop after monitoring points.

8.1.4DISPLAYING DEVICE ANALOGUE VALUES - CV, TV, ETC

Once points have been selected for display, the MXP will display at least one line for each selected point, each time the point replies to a poll (or sends an interrupt message).

For those devices with two sensors (814PH, 814CH) with both sensors configured, two lines will be displayed – one line for temperature and another line for smoke or CO.

Colour logging may be selected with the “CO” command to make the displayed log clearer. Green is used for heat sensors, yellow for photo sensors, magenta for CO sensors, cyan for ionisation sensors, and white for ancillaries. A brown/yellow background is used for values in fault, green background for values in pre-alarm, red background for values in alarm.

An example line of the displayed values is

T=165; P= 2; HEAT= 20; Fl= 20; SL= 20; RoR= 0; SLRoR= 0 T=xxxx refers to the time in seconds. It recycles back to 0 after 4290 seconds. P=xxx refers to the point number (1 .. 200).

The format is designed to be both human readable and suitable for capturing and importing into a spreadsheet. In the latter case, it is suggested that “delimited” text import is used, with “=” and “;” being used as delimiters.

The following paragraphs describe the parts of the log specific to each device type.

8.1.4.1Heat Sensor of 814H, 814PH, and 814CH

T=165; P= 2; HEAT= 20; Fl= 20; SL= 20; RoR= 0; SLRoR= 0

HEAT=xxx gives the raw value received from the detector converted to °C.

Fl=xxx gives the filtered temperature (CV) in °C. This is the value which is compared with the threshold to decide if a pre-alarm exists.

SL=xxx gives the filtered and slope limited temperature (SLV) in °C. This is the value which is compared with the threshold to decide if an alarm exists. This item will not be displayed if there is no fixed temperature alarm configured, e.g. if the heat sensor is used only to enhance the smoke or CO.
