Summary:
How do I set up Citect to use the D Sy/Link card? 

Solution:
The board memory address is set via dip switches.
Boards form
Board name: User supplied unique name
Board type: SQUARED
Address: Board's memory start segment (in hexadecimal). 0xCA00 to 0xD300 in 0x100 (4K) increment
I/O Port: Board's route number, it must be between 0 and 99
Interrupt: Board's interrupt request line.
Special Opt: Specify the following network port parameters:

-b Enable SY/LINK to receive broadcast messages from the network. The default is to disable broadcast.
-s Set maximum network size to 100 instead of the default of 31.
-rN Set the network baud rate. Where N is 0,1,2 or 3 for network baud rate of 62.5K, 125K, 250K and 500K respectively. The default is 500K.

Ports form
Port name: User supplied unique name
Port number: not used
Board name: Use the "Board name" from the Boards form
Baud rate: as per the SY/LINKboard
Data bits: as per the SY/LINKboard
Stop bits: as per the SY/LINKboard
Parity: as per the SY/LINKboard
Special Opt: Specify the following RS-422 port parameters:

-b Enable the RS-422 port to receive broadcast message from the network. The default is to disable broadcast.
-d Prevent other network devices from communicating to the RS-422 port.
-n Set the RS-422 port to Net-To-Net mode. The default is SY/MAX mode.
-p Set the RS-422 port to Peripheral mode.

I/O Devices form
Name: User supplied unique name
Number: Network wide I/O device number
Address: Route to the PLC. A blank route field means access to the registers on the SY/LINK card.
Protocol: SQUARED
Port name: Use the "Port name" from the Ports form

Standard citect.ini options

[SQUARED]
MaxPending = 1
Block = 64 bytes
Retry = 1
Delay = 0
