Setting up a port means initializing controller serial ports to use specific devices, such as the CRT/KB. Initializing ports involves setting up specific information for a port based on the kind of device that will connect to the port. This is done on the teach pendant PORT INIT screen.
The controller supports up to four serial ports. Several different kinds of devices can be connected to these ports.
Up to four ports are available, P1-P4. Table 1, " Ports P1 - P4 " lists the ports. You can set up ports P2 through P4 if you have them, but you cannot set up the teach pendant port, P1.
Table 1. Ports P1 - P4
Port | Item Name on Screen | Kind of Port | Use | Default Device |
---|---|---|---|---|
P2 | JRS16 RS-232–C | RS-232-C | Any device | Maintenance Console |
P3 | JD17 RS-232–C on Main CPU card | RS-232-C | KCL | |
P4 | JD17 on Main CPU card. This port is displayed on the teach pendant if $RS232_NPORT=4. | RS-422 | No use |
Port P3 and P4 share one baud rate generator. Therefore, they must both function at the same baud rate. If you change the baud rate of one port, both ports will function at the new baud rate.
