GE GFK-1541B manual Serial Port Parameters

2

Status Length: This is the sum of the LIS bits and the Channel Status bits. This value is automatically set to either 80 bits (for %I and %Q Status address locations) or 5 words (for %R, %AI, and %AQ Status address locations).

Network Routing Pair #1, #2, #3: These parameters are used to define an IP routing partnership with another network adapter within the same PLC system. Network routing pairs is an advanced feature that should be set only by individuals who have detailed knowledge of PLC communications.

Network Time Sync: Selection of the method used to synchronize the real-time clocks over the network. Currently the choices are None (for no network time synchronization) and SNTP (for synchronization to remote SNTP servers on the network).

Serial Port Parameters

Data Rate (bps): Data rate (bits per second) for the port. Choices are 300, 600, 1200, 2400, 4800, 9600‡, or 19200*.

Parity: Type of parity to be used for the port. Choices are None‡, Even, or Odd*.

Stop Bits: Enter the number of stop bits. Choices are 1*‡ or 2.

Flow Control: This parameter is currently not used by the Ethernet Interface. Changing this parameter has no effect.

Turnaround Delay: Turnaround delay time (in milliseconds) to be used for the port. Choices are None*‡, 10 ms, 100 ms, or 500 ms.

Timeout: This parameter is currently not used by the Ethernet Interface. Changing this parameter has no effect.

*Default selection for the Software Loader Port.

‡ Default selection for the Station Manager Port.
