CX8030, CX8031 - Introduction
In the basic version the CX80xx contains a 512 MB MicroSD card. A fieldbus interface, an Ethernet interface and a K-bus or E-bus interface are included as standard.
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 load 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.
CX8030
The CX8030 is a controller with an Ethernet connection, via which it is programmed and/or configured, and a PROFIBUS master interface on an RS485 basis with a D-sub connection. Optionally, the CX8030 can also be operated as a PROFIBUS slave.
Alternatively K-bus or E-bus terminals can be series-connected; the CX8030 automatically detects which type of terminal is connected during the start-up phase. The controller is programmed with TwinCAT via the Ethernet interface.
CX8031
The CX8031 is a controller with an Ethernet connection, via which it is programmed and/or configured, and a PROFIBUS interface on an RS485 basis with a D-sub connection. Physically the CX8031 has only one D-sub interface, but this can be used in such a way that it appears as if 4 devices are on the bus. The advantage of this is that more data can be exchanged and that the CX8031 can communicate as a DP/DP coupler with a second PROFIBUS master.
Alternatively K-bus or E-bus terminals can be series-connected; the CX8031 automatically detects which type of terminal is connected during the start-up phase. The controller is programmed with TwinCAT via the Ethernet interface.
