ASIC Protocol - 1

ASIC Protocol

1. OverviewThis driver supports the ASI communication protocol of ASI Controls. This protocol provides

communication access to a network of ASI controllers from XPanel.

2. Communication Setup : XPanel

(1) Create a new device.

For creating a new device activate the menu ‘Tools’->’I/O Devices’ or icon in tool-

bar. Following picture shows the first step of creating a new device.

I/O Device Name

Give a device name. This name will be used in the TAG configuration window of

database accompanied by the ‘Station Name’.

(2) Select a device type : ‘ASI Communication Protocol’

After selecting the ‘OK’ button of previous step, ‘Serial Communication Configuration’

dialog box will be popped up as shown in following picture.



ASIC Protocol - 2

In this window, select the ‘Device Type’ as ‘ASI Communication Protocol’ and configure

the proper serial communication parameters. Ensure that those parameters are matched

with PLC configuration.

Local ID

The host address of XPanel has to be designated in this window. It is 16 bits value

between 1 and 65535. There are reserved address ranges which cannot be used

by XPanel or DDC. Please refer to the DDC manual from ASI Controls for more

information about the address.

(3) Create a station

Move to the ‘Station’ tab of ‘Serial Communication Configuration’ dialog box.

In this dialog box, all the connected PLC stations can be configured and registered to the

XPanel. Each field can be configured with following rules.

Station Name

Give a name to the PLC. This name will be used in the database window

accompanied with the ‘Device Name’.

Station Type

Choose the type of connected PLC among the “ASIC”.

Network ID

This field has no effect.



ASIC Protocol - 3

Station No.

Specify a decimal number between 1 and 65535. This number must be matched

with the node address of the DDC.

16Bit Data Swap

This option swaps bytes of all word or double word sized data. Following diagram

shows an example of byte swapping.

Almost all of the data type will be influenced by this option except INT8 / UINT8 /

BCD8 / UBCD8.

32Bit Data Swap

This option swaps words of all double word sized data. Following diagram shows

an example of word swapping.

1234ABCDh ABCD1234hDouble Word Data

INT32 / UINT32 / BCD32 / UBCD32 / FLOAT type of TAG values will be influenced

by this option.

Using Checksum

This field has no effect. This communication driver always checks the check-sum.



ASIC Protocol - 4

Comm. Error Message Pop Up

If this item is checked, XPanel displays a communication error notification

message at every Rx and Tx error.

Otherwise(unchecked), XPanel does not display the message at data receive error.Only when there is data transmit (writing a TAG value to the station) error, the

notification message is popped up. This message box will be closed automatically

about 5 seconds after.



ASIC Protocol - 5

3. Data Address

XPanel supports reading object and table data from DDC. These two data can be referencedby following TAG address format.

Obj No / Table No

Designate the object (table) number of data location. Please refer to the object definition

of connected DDC, for more information about object.

Size

Designate the data type. It can be 1 (BYTE) or 2 (WORD).

Offset

Designate the byte offset within the table.

Index

Designate the assigned index number within the given object.

Attribute

Designate the attribute number of data.

:Bit No

Designate the bit number. This bit address notation is used in digital TAG. Notice that

the TAG with this bit number only can be read. That is, the digital TAG writing is not

supported with ASIC protocol driver.

Bit number has to be within the range of data size. In case of a table (T) or object (O)

with size 1 (BYTE), bit number can be between 0 and 7. Elsewhere, object with size 2

(WORD), bit number can be between 0 and 15.

[Address Examples]

O33.2.0.0 : Object 33, WORD, Index 0, Attribute 0

T10.0 : Table 10, Byte offset 0

O32.1.0.8 : Object 32, BYTE, Index 0, Attribute 8

O3.2.11.0:0 : Object 3, WORD, Index 11, Attribute 0, Bit 0

[Object]

O[Obj No].[Size].[Index].[Attribute](:Bit No)

[Table]

T[Table No].[Offset](:Bit No)



ASIC Protocol - 6

[TAG Data Type]

ASIC DDC supports two types of data, BYTE and WORD. If the data type of TAG was

larger than that, XPanel will read next continuously positioned data for making designated

data. For example, if UINT32 type of TAG referred to the address of T1.2, XPanel will readT1.2, T1.3, T1.4 and T1.5 for assembling the UINT32 data.
