Mounting
The devices can be snapped onto standardized rails.
The power supply, LonTalk, RS485 and KNX connections have plug-in screw
terminal blocks. The other interfaces are quick plug-in connections.
Instead of the front cover a PXA40-RS... option module can be fitted on the device.
Commissioning
In order to prevent equipment damage and/or personal injuries always follow local
safety regulations and the required safety standards.
The plant operating program is downloaded using the CFC from XWP – locally via
the automation station's RJ45 interface or via the network (BACnet/IP or
BACnet/LonTalk).
Use the PX Design tool in XWP for setting the control parameters and the
configuration data. Data visible on the network may also be edited with an operator
unit PXM20 / PXM20-E (BACnet / LonTalk or BACnet / IP).
Part of the data can also be edited locally using the operator unit PXM10
(not available for PX KNX).
Use the Point Test Tool.
The network addresses are configured with XWP. For unique identification in the
network (BACnet/IP or BACnet/LonTalk), press the Service button with a long,
pointed object or send a wink command to the appropriate system controller
(service LED blinks).
• Variant via V24:
If the Force Firmware Download Key is pressed for approx. 10 s during a
restart (reset), the current D-MAP program is deleted from the FLASH.
The system controller waits briefly for the signal to activate the FWLoader and
then starts the system controller.
• IP variant: (for PXC001-E.D, significantly faster than via V24)
Press the Force Firmware Download key for 5 seconds (without hitting the
reset button).
Prerequisite: A node setup of the controller has been conducted and no
application is loaded or it was deleted in the CFC by clear/reset (communication
settings remain – which would not be the case when restart erasing by pressing
the reset key).
For details see the Firmware Download Tool User's guide, CM110626.
