on_lighting_label_text(source_addr, group_addr, ﬂavour, language_code, label)

Event called when a group address’ label text is updated.

Parameters

• source_addr (int) – Source address of the unit that generated this event.

• group_addr (int) – Group address to relabel.

• ﬂavour (int) – “Flavour” of the label to update. This is a value between 0 and 3.

• language_code (int) – Language code for the label.

• event_bytes (str) – Label text, or an empty string to delete the label.

on_mmi(application, bytes)

Event called when a MMI was recieved.

Parameters

• application (int) – Application that this MMI concerns.

• bytes (str) – MMI data

on_pci_cannot_accept_data()

Event called whenever the PCI cannot accept the supplied data. Common reasons for this occurring:

•The checksum is incorrect.

•The buffer in the PCI is full.

Unfortunately the PCI does not tell us which requests these are associated with.

This error can occur if data is being sent to the PCI too quickly, or if the cable connecting the PCI to the

computer is faulty.

While the PCI can operate at 9600 baud, this only applies to data it sends, not to data it recieves.

on_pci_power_up()

If Power-up Notiﬁcation (PUN) is enabled on the PCI, this event is ﬁred.

This event may be ﬁred multiple times in quick succession, as the PCI will send the event twice.

on_reset()

Event called when the PCI has been hard reset.

pci_reset()

Performs a full reset of the PCI.

pciserverprotocol Module

class cbus.protocol.pciserverprotocol.PCIServerProtocol

Bases: twisted.protocols.basic.LineReceiver

Implements a twisted protocol listening to CBus PCI commands over TCP or serial.

This presently only implements a subset of the protocol used by PCIProtocol.

application_addr1 = 255

application_addr2 = 255

basic_mode = True

checksum = False

connect = False
