Functions

These freely programmable automation stations provide the infrastructure for the

provision and processing of system-specific and application-specific functions.

Apart from the freely programmable control functions these units comprise integrated

convenient management functions such as:

•Alarm management with alarm routing throughout the whole network. Three level

alarm management (simple, basic and enhanced) with safety control transmission

and automatic transmission monitoring

•Time schedulers

•Trend functions

•Remote management functions

•Access protection for the whole network with individually defined user profiles and

categories

These automation stations are freely programmable with the D-MAP programming

language (follows closely CEN Standard 1131). All function blocks available in libraries

are graphically linked with the plant operating programs.

Communication is via Ethernet with the international standard BACnet protocol.

Both peer-to-peer communications with other automation stations and connections to

the PXM20-E operator units are supported.

The devices communicate via an open LonTalk system in accordance with the inter-

national standard BACnet protocol. Both peer-to-peer communications with other

automation stations and connections to the PXM20 operator units are supported.

The devices communicate via the public telephone network in accordance with the

international standard BACnet protocol.

There are various options for operation of the PXC…U automation stations:

•QAX... room unit connected to the PPS2 interface. A maximum of five room units

QAX… (not QAX5…) can be connected. Details on the PPS2 communication are

described in the DESIGO Technical principles manual (chapter "I/O blocks", section

"PPS2 addressing").

•Local PXM10 operator unit, either plugged into the automation station or connected

via PXA-C1 cable

•Network-compatible PXM20 operator unit (BACnet / LON)

for operation of the local automation station or an automation station in a network,

either plugged into the automation station, or connected via PXA-C1 cable

•Network-compatible PXM20-E operator unit (BACnet / IP)

for operation of the local automation station or an automation station in a network,

either plugged into the automation station, or connected to the Ethernet network or

an Ethernet switch.

•PX-WEB: The PXA30-W… extension module is used to activate the Web server,

allowing operation with a Web browser, a touch panel or a PDA.

The transfer of alarms via SMS or e-mail can be configured in the automation

station.

Technology

The data between the automation station and the I/O modules are exchanged via the 3-

core P-bus.. Each module on the same P-bus is provided with its own address between

1 and 255. The addresses are set with address plugs.

The automation stations provide the connected I/O modules with a DC 23 V supply.

The automation station load by I/O modules is expressed by the number of load units of

12.5 mA each (details of the calculation of the total load see the I/O module range

document CM2N8100).

Mounting instructions

The modular automation stations are particularly suitable for control panel front

mounting as well as flush-panel and wall mounting.

For control panel front mounting the device socket is held in place by clamps at all four

corners (no tools required for mounting). The upper housing is fixed to the device

socket with two screws.

For flush panel mounting the plug-in terminal blocks can be repositioned whilst at the

same time reversing the support bars to enable front access. The support bars absorb

the screw force and also provide the means of fixing the device to the wall.

Instead of the front cover a PXM... operator unit can be fitted on the modular auto-

mation station.

For PXM20-E mounting (ethernet cable) see the mounting instructions delivered with

the operator unit!

•Insert

the PXA30… extension module fully into its socket (to a depth of 1.5 mm),

using slight force. Then check that the plug is safely snapped on to ensure safe

and smooth functioning.

•Do not touch the connector pins (electrostatic discharge)

Commissioning

In order to prevent equipment damage and/or personal injuries always follow local

safety regulations and the required safety standards.

Electronic parts may be damaged if the upper housing is inserted or

disconnected with the supply voltage switched on (hot plugging).

Download the plant operating program to the automation station with the PX Design

tool in the DESIGO TOOLSET, direct via the RJ45 connector or the LON bus.

Use the PX Design tool in the DESIGO TOOLSET for setting the control parameters

and the configuration data. Data visible in the network can also be changed with the

PXM… operator unit.

It is possible to test field devices and the wiring as soon as the power supply is

connected, without first downloading the plant operating program.

The test is carried out with a PXM20 or PXM20-E operator unit.

The network addresses are configured with the DESIGO TOOLSET. In order to provide

a unique identification in the LON network press the service pin with a sharp implement

(COM1 on the front, see page 4) or send a wink command to the relevant automation

station (service LED flashes).

Three service buttons are provide under the front cover:

Connected to

LON-Bus If this key is pressed during a restart (Power-

fail) the current D-MAP program is deleted

from the FLASH.

The automation station waits a short while for

the signal to activate the FWLoader and then

starts the automation station..

Connected to

Ethernet / IP If this key is pressed for >5 s, the automation

station waits for a firmware download via

Ethernet.

Cold Start

Pressing this button during a restart forces a

cold start.

ABRESET

RESET Forces a restart

Maintenance

Lithium batteries usually have a life span of at least four years. The automation station

automatically sends a system event in order to indicate a low charge.

After the "Battery low" event there are several months of remaining life span.

To change the battery, remove the front cover. As long as the supply voltage is

connected, the battery may be removed for unlimited time.

To prevent hardware damage by electrostatic discharge (ESD), a wrist strap with earth

cable must be used during the battery change.
