Run

Normal processing of the user program after Start. Where a programming unit is connected via a PCD8.K11x in PGU mode (e.g. PG5 in PGU mode), the CPU automatically goes into the Stop state and not the Run state; this is for

safety reasons

Run conditional

Conditional Run state. A condition has been set in the debugger (Run until…), which has not yet been met

Run with error Same as Run, but with an error message

Run cond. with error Same as conditional Run, but with an error message

Stop

The Stop state occurs in the following cases:

• Programming unit in PGU mode connected when the CPU was switched on

• PGU stopped by programming unit

• Condition for a COND.RUN has been met

Stop with error Same as Stop, but with an error message

Halt

The Halt state occurs in the following cases:

• Halt instruction processed

• Serious error in user program

• Hardware fault

• No program loaded

• no communication module on an S-Bus PGU or Gateway Master port

System diagnostics If the PLC doesn‘t go to RUN after 2 minutes, you have to send it for repair

Reset

The RESET state has the following causes:

• Supply voltage too low

• Firmware not starting up

the DIP switch setting. Inside the communication module there is 8-poistion switch among which

the SA2 and SA3 are used to set the device address. In the actual application, when the DIP switch

is set to the side “ON”, it represents “0” of the binary system and “1” on the opposite end. Once the

communication module is integrated with the BANnet gateway, its address range is 1 thru 4. See

the Operation Instruction of the Communication Module for more details about the setting of the

DIP switch.

Appendix B BACnet Protocol

1 Brief Introduction to the BACnet Protocol

1.1 What is BACnet

BACnet - A Data Communication Protocol for Building Automation and Control Networks - see

bacnet.org. BACnet is a standard data communication protocol for Building Automation and Control

Networks. BACnet is an open protocol, which means anyone can contribute to the standard, and

anyone may use it. The only caveat is that the BACnet standard document itself is copyrighted

by ASHRAE, and they sell the document to help defray costs of developing and maintaining the

standard (just like IEEE or ANSI or ISO).

1.2 BACnet Collapsed Architecture

BACnet is based on a four-layer collapsed architecture that corresponds to the physical, data

link, network, and applicationlayers of the OSI model.

BACnet Layers Equivalent OSI Layers

BACnet Application Layer

BACnet Network Layer

ARCNET EIA-485 EIA-232 UDP/IP

BACnet is dened for several physical layers.

BACnet/IP has only later been added to the original group.

1.3 BACnet device proles

Today 6 device proles are dened with BACnet:

BACnet Operator Workstation (B-OWS)

BACnet Building Controller (B-BC)

BACnet Advanced Application Controller (B-AAC)

BACnet Application Specic Controller (B-ASC)

BACnet Smart Actuator (B-SA)

BACnet Smart Sensor (B-SS)

Any device that implements all the required BACnet capabilities for a particular device type

and interoperability area may claim to be a device of that particular type.Devices may also provide

additional capabilities and shall indicate these capabilities in their PICS.

1.5 BACnet services

BACnet services are divided into ve segments:

1) Alarm and event Services

2) File Access Services

3) Object access Services

4) Remote device management Services

5) Virtual terminal Services

For each device prole certain services are mandatory.

1.6 Description of a service: BIBB

BACnet Interoperability Building Blocks (BIBBs) are collections of one or more BACnet

services. These are prescribed in terms of an "A" and a "B" device. Both of these devices are

nodes on a BACnet internetwork. In most cases, the "A" device will act as the user of data (client),

and the "B" device will be the provider of this data (server). In addition, certain BIBBs may also be

predicated on the support of certain, otherwise optional, BACnet objects or properties and may

place constraints on the allowable values of specic properties or service parameters.

1.7 Description of a device type: PICS

PICS protocol implementation conformance statement All devices conforming to the BACnet

protocol shall have a Protocol Implementation Conformance Statement (PICS) that identies all of

the portions of BACnet that are implemented.

A PICS is a written document, created by the manufacturer of a device, that identifies the

particular options specified by BACnet that are implemented in the device. A BACnet PICS is

considered a public document that is available for use by any interested party.
