To establish communication with a device, the associated Board, Port and I/O Device need to be correctly configured in Plant SCADA Studio's Topology activity.
If you use the Express Communications Wizard to connect to a device, these settings will be automatically configured for you. However, if you need to manually configure them, use the settings outlined below.
Boards
|
Field |
Value |
|---|---|
|
Board Type |
For a KT, KTX, KTXD, or PKTX card, enter CIKT. For a 5136-SD or 5136-SD-PCI card, enter SSTAB. |
|
Address |
For a KT board, enter the address of the card (e.g. 0xCC00). For a KTX or KTXD board, enter the first two digits of the address of the card (e.g. 0xD0). For a PKTX board, enter 0xFFFF. For a PKTXD board channel A, enter 0xEEEA (0xEEEE) For a PKTXD board channel B, enter 0xEEEB. The driver uses this to determine the type of card and then auto-detects the address. Do not append zeros. For a 5136-SD board, enter the address of the card, which needs to lie on a 1K boundary (i.e. it can be changed in 0x0400 increments - e.g. 0xCC00). For a Series 2 card the board address needs to lie on a 2K boundary (i.e. it can be changed in 0x0800 increments - e.g. 0xD800). For a 5136-SD-PCI interface board, enter 0xFFFF. This value indicates that the board is a PCI board. |
|
I/O Port |
For a KT, KTX, KTXD, or PKTX board, enter a unique DH+ address in Octal (e.g. 0o77) If using both channels of a PKTXD card, you should give each channel a unique address. For a 5136-SD board, enter the I/O Port address of the card (e.g. 0x250). For a 5136-SD-PCI board, leave this field blank. |
|
Interrupt |
For a KT, KTX or KTXD - and polling is not being used - enter the IRQ number set on the card. For a PKTX card, leave this field blank For a 5136-SD card, leave this field blank. For a 5136-SD-PCI card, enter zero. |
|
Special Options |
For KT, KTX, KTXD, or PKTX ISA boards the following special options are available: For KT, KTX, KTXD, or PKTX PCI boards the following special option is available: For the 5136-SD board the following special options are available: For the 5136-SD-PCI board the following special options are available: |
Ports
|
Field |
Value |
|---|---|
|
Port Number |
A unique number for each port, starting from 1. |
|
Baud Rate |
Leave this field blank. |
|
Data Bits |
Leave this field blank. |
|
Stop Bits |
Leave this field blank. |
|
Parity |
Leave this field blank |

I/O Devices
|
Field |
Value |
|---|---|
|
I/O Device Address |
Specify the PLC address as: xKT:C[options],u where: x = the board number. If the number is not specified in the ports for then use 1. For example: 1KT:0,1 specifies Port ID 1KT for access to PLC Station 1 . |
|
I/O Device Protocol |
Enter ABTCP5. |
