CX8091 - Introduction

The CX8091 is a controller with a switched Ethernet port. The BACnet/IP or OPC UA protocols are supported.

Alternatively K-bus or E-bus terminals can be series-connected; the CX8091 automatically detects which type of terminal is connected during the start-up phase.

The CX8091 is programmed with TwinCAT 2 via the fieldbus interface or the additional Ethernet interface.

In the basic version the CX80xx contains a 512 MB MicroSD card. The basic equipment includes two Ethernet interfaces as well as a K-bus or E-bus interface.

The smallest task time to be used is 1 ms (a task time of 1 to 50 ms is recommended for the I/O data, further tasks can also be set slower).
When using shorter cycle times, the total system utilization rate is to be observed.
If too short a cycle time is selected, the Web visualization and remote desktop may operate very slowly or cause timeouts.
The user is responsible for projecting and configuring his system such that it is not overloaded.
