Online Access

Preferred driver for online access: 3S UDP block driver BlkDrvUdp. This driver allows to scan and select the connected PLC’s.

Alternative: 3S TCP/IP block driver. This driver requires at least 2 sockets:

• 1x driver “BlkDrvTcp” on port 11740
• 1x listen on port 11740 if PLC has established online connection

Note

Online access can be established from:

• Automation_BuilderCommand ‘Login’: Menu ‘Online’
• IEC 61131-3 editor OPC DA server
• Panel CP600 series

Each established connection needs one socket. In addition one socket on port 11740 is listening.

1. Startup the PLC.

   ⇒

   One socket on port 11740 (listen).

2. Login from Automation_Builder via driver “BlKDrvTcp”.

   ⇒

   2 sockets on port 11740 (1x online, 1x listen)

3. Additional login out of OPC server with the same driver.

   ⇒

   3 sockets on port 11740 (2x online, 1x listen)

4. Additional connect CP600 via driver “BlkDrvTcp”.

   ⇒

   4 sockets on port 11740 (3x online, 1x listen)
