"To run a SoftLogix 5 controller with RSLinx and RSView32,
configure the TCP/IP channel and use the SOFT5 driver or the
AB_ETH driver.
For the SOFT5 driver, when configuring the SoftLogix 5 driver in
RSLinx, enter the IP address or UNC name of the SoftLogix 5
controller in the InternetAddress Mapping table.
If the SoftLogix 5 controller is not running on the same computer
as RSLinx, the Windows
®
XP, Windows 2000 user account that is
running RSLinx must be a member of the SoftLogix
Administrators group on the SoftLogix 5 computer.
For the AB_ETH driver, when configuring the Ethernet driver in
RSLinx, enter the IP address of the SoftLogix 5 controller in the
Internet Address Mapping table.You must also enable the

Mình đọc đoạn này không hiểu lắm. Trong RSLinx cũng không thấy driver SOFT5.
