Siemens Building Technologies VISONIK Building Process Station BPS / NetBPS CM2N8305en
Landis & Staefa Division 05.10.2000
The PRV… basic units with P-bus connection supply DC 24 V to the connected I/O
modules via the P-bus. The I/O module load units are available in the following
documents:
− N8102: "Basic Data of the I/O Module System"
− N8111 … N8171: data sheets on the individual I/O modules
The maximum number of load units for the basic unit types with P-bus is available in
section "Type summary".
In this variant having two P-bus connections, distribute the I/O modules to be
connected so that the load units are equally divided between the two P-bus
connections.
The P-bus interface is not electrically isolated from the unit's electronics.
The following rules apply to selecting the station type:

BPS/NetBPS with P-bus and
I/O modules
The sum of the load units LU of all
connected I/O modules (see section
"Type summary") determines the
type.

PRV2.00 FLN or MONOGYR master,
CFE applications without I/O
module connection
If, in addition, a P-bus with I/O module
is connected, use types PRV2.32, 64,

If a VISONIK system is engineered using the European Tool Set ETS, the tool
suggests the appropriate station type.
2)
We recommend separate stations.
The PVA3...program card depends on the required functionality. Refer to data sheet
N8317 for detailed information.
Number: Up to 224 I/O module points can be generated in the BPS.
Addressing: Via address plugs 1 to 112.
Note: Order I/O modules and address plugs separately.
Mounting notes
Observe both mounting depth and side distance for flush panel mounting or mounting
inside the cabinet. Remember to include space requirements for COM1 communication
card connections on the side; see "Dimensions".
Do not touch electrical contacts and components on the open unit; electrostatic
discharges may destroy sensitive components.
The basic unit is delivered with a neutral label on the compartment. The label bearing
the system name VISONIK is an accessory that can be exchanged when mounting the
BPS/NetBPS.
The basic unit is delivered with mounting instructions.
