Operation Overview
The gateway comprises two sections; the BACnet MS/TP device and the P1 network reading data
base.
BACnet Device
The gateway is BTL listed, conforming to the BACnet standard’s requirements for device & object
discovery and network communication initiations and responses.
During commissioning the following should be configured:
Node # (local network unique number)
Device Instance (system-wide unique number)
MS/TP network baud rate
Maximum Master (MM), set to the highest node number existing on the network, for limiting
network traffic to only those devices that exist on the network
250 AV objects relating to the P1 network devices’ data points being read, AV4…AV253
P1 Network Gateway
250 device data points may be configured, from up to 32 P1 devices. Each data point constitutes a
BACnet object (AV).
It is important to have the P1 device manufacturer’s manual available to assist with P1 point address
and type scaling.
Each point of the gateway data base consists of:
1. Device addresses
2. Point numbers within the device addresses
3. Sensor type relating to each point (as defined in the scaling table)
4. A point type; LDI, LDO, LAI, LAO represented as a number, 1…4 respectively
BACnet Priority Array
The BACnet protocol utilises a Priority Array for each object to enable various network devices to take
control of a device’s object based on the level of need. The priorities are in the range 1 (high priority) to
16 (Auto operation).
In respect of this device:
The point database objects are NULL priority, signified by ‘17’ when viewing the points in
engineering Terminal mode
Manually overriding a point value via terminal mode invokes priority level 9
Release of a manual results in an object reverting to NULL or next lowest and still valid priority
level if it has been commanded from another device in the system (such as the BMS)
For normal reading of the P1 network points should always be at NULL priority
HRW HPE-BNP1BUS V401 Manual 120201.doc E. & O. E. / Subject to change without notice Page 3 of 18
Terminal Mode
An HPECOM (serial comm. port) or HPECOMU (USB) data cable is used for terminal mode between
the gateway and a PC running a terminal program. HyperTerminal or Indigo Terminal Emulator from
Shade Blue are recommended. A USB port <> Serial comm port (DB9) converter may be required for
HPECOM if the PC being used does not include a Com 1 serial port.
The following settings reflect HyperTerminal. Please contact us if you require assistance setting up
Indigo.
HyperTerminal Settings
For successful communication between HyperTerminal and the device, initial Properties setup of
HyperTerminal should be as per the screen prints below.
‘Connect to’ Comm Configuration: ‘Settings’ General:
9600
‘Settings’ ASCII Setup:
HRW HPE-BNP1BUS V401 Manual 120201.doc E. & O. E. / Subject to change without notice Page 4 of 18
Additional Settings
Some PC platforms may need keyboard response adjustment for initial Terminal Mode success. These
settings may be done via the PC Control Panel >> Keyboard Settings:
Fastest Repeat rate
Shortest Delay time
Fastest Cursor Blink rate
Connecting at 76800 Baud Rate
Because HyperTerminal does not support 76800 baud then after setting to 76800 the device baud rate
will remain at 9600 baud for HyperTerminal communication and switch to 76800 after Writing the new
baud rate and eXiting terminal mode.
To allow later terminal communication a device set with 76800 baud will operate at 9600 baud for the
first 5 seconds after a power-up. If no attempt to connect the terminal at 9600 baud is made within 5
seconds of a power-up then the device will automatically switch to 76800 for normal network operation.
Saving HyperTerminal Settings
For ease of connection it is recommended to save the HyperTerminal setup for each baud rate you may
wish to use with an easily recognised configuration name. For example:
HPECOM 24 (2400)
HPECOM 48 (4800)
HPECOM 96 (9600)
HPECOM 19.2 (19200)
HPECOM 38.4 (38400)
HPECOM 57.6 (57600)
Break in to Terminal Mode
When HyperTerminal is running and the HPECOM cable is connected to the device the initial terminal
screen will be receiving an ASCII character dump which is the BACnet transmission from the device.
The ASCII dump will appear differently with different device address setting and if HyperTerminal baud
rate is different to the baud rate set in the device. Below is an illustration of how the ASCII dump will
look for a device at default settings; address 98 and 9600 baud.
To break in to terminal mode set Caps Lock on and hold the ‘T’ character key continuously
(TTTTTTT…). After five (5) T’s have been sent to the device it will switch to terminal mode. At this point
the BACnet activity on the network will be halted and the device will display the default user screen.
