• 6K as a server. The 6K waits for a PC to establish a connection with it and then provides
information on a continual or requested basis. The PC communicates with the 6K using
the COM6SRVR Communications Server, which is also what Motion Planner uses to
communicate with the 6K (for details, refer to the COM6SRVR Communications Server
Programmer’s Reference). The 6K does not support simultaneous connections with
multiple clients (PCs).

• Combination of server and client. For example, the 6K could be the client for an
OPTO22 (server) and an Allen-Bradley PLC (server). At the same time, a software
program running on a PC could be using the 6K as a server.
