Frequently asked questions

Refer to Chapter 3 of the user manual for a detailed start-up procedure. It outlines the DIP switch settings for configuring the adapter for RIO communications. You will need to set the protocol, Baud rate, rack size, redundancy, starting group, and address.

The PLC COM ADPTR SER A supports 57.6K, 115K, and 230K baud communication rates. The specific rate can be selected using DIP switches as described in the manual.

Similar to configuring for RIO, Chapter 3 of the manual describes the DIP switch settings for DH+ communication. You'll need to set the protocol, Baud rate, and the station address on the adapter board.

The manual recommends Belden 9463 twinaxial cable for connecting the adapter to RIO and DH+ networks. It also specifies minimum cable length and proper termination requirements.

The adapter has four analog inputs and four analog outputs with a range of +10V and 12-bit resolution. You can use the parameters in Chapter 4 to scale the values to your desired units.

Chapter 6 of the user manual provides information on fault and status LEDs and fault codes. You can use the LEDs to diagnose any issues and the fault codes to identify specific problems.
