A User's Guide to Configuring Serial Ports for DirectLOGIC PLCs: A Two Part Series

The capabilities of Port 2 of the DL06, DL250-1 and DL260 CPUs are often overlooked when designing a process control network. Like Port 1, Port 2 can be used for programming the CPU or connecting other RS-232 devices, such as an operator interface panel, to the PLC. Unlike Port 1, Port 2 supports different types…
