Issue Details

What protocols are available for connecting a compact FieldPoint 180x to my network?

Solution

Compact FieldPoint 180x devices can be connected to an Ethernet network, an RS-232 network, or both. When using Serial communication, you can communicate with I/O modules using Modbus ASCII or Modbus RTU. When using an Ethernet connection, you can use Modbus TCP.

Note:

  • Ethernet/IP 16.0 is not an available protocol, as the newest Ethernet/IP driver (NI-Industrial Communications for Ethernet/IP 16.0) is not compatible with Compact FieldPoint devices.
  • Ethernet modules can read from or write to FieldPoint resources simultaneously.
