GENERAL DESCRIPTION

CPC12 – transparency through webserver and fieldbus connection
The requirements of machine and plant construction regarding machine uptime and a consistently high production quality are increasing. Stable processes are based on a reliable and transparent DC24V pro-tection and power distribution system. E-T-A’s CPC12 bus controller has a separate DC24V power supply and allows independent supply of the circuit protectors. It records all status information and measuring values. These data are visualised with the internal webserver. Via the field bus interface, the data are also made available to the superordinate control systems.

E- T-A’s REX12D system in combination with the CPC12 bus controller was designed specifically for the requirements of the machine construction and process control industry. The REX12D modular power distribution system combined with the CPC12 bus controller meets all requirements.

• Maximises plant and machine uptime through clear failure detection, high transparency and remote diagnosis
• Saves space through a slim design of the circuit protectors and the potential modules
• Increases flexibility of system plan-ning through many different modules meeting the demands of DC24V power distribution

By clicking on these areas, it is also possible to navigate the circuit breaker overview page to the different parts of the system. The cur-rently displayed area is shown with a blue line below it.If the system is operating, the colour is green. If there is a warning or an error, it will be highlighted with the colours orange or red. A gray filled rectangle means that the circuit breaker was switched off manually at the device. If the rectangle is only outlined, no device is connected.

CIRCUIT BREAKER OVERVIEW

After the functionality of the system has been de-scribed in the previous chapter, the middle overview of the interface will be discussed now. This shows the various electronic circuit breakers lined up. Each channel shows the output voltage and current as well as different status messages. The upper rectangle contains the currently set cur-rent rating. Depending on the recent switching state or message, the box changes its colour. Gray = Off, Green = On, Yellow = Warning, Red = Trip Below that, different points clarify the status of the channel. These can also light up in the colours green, yellow, red. The blue line above and below illustrates the se-lected circuit breaker.

CIRCUIT BREAKER FUNCTIONALITY

The last third of the overview page displays addi-tional information and functions for the selected cir-cuit breaker. Three different tabs can be selected on the left-hand side. These are explained below:

Parameter
The first tab displays general information about the circuit breaker, such as the serial number and the hardware and software version. Furthermore, the last error reason can be read out. The possible parameters that can be set have al- ready been explained in the “Batch Edit De-vice” function. The different input fields can be adjusted by the integrated arrow keys. If the required value is reached, the new setting can be loaded into the de-vice via the “Write Parameter” button. The “Restore Factory Settings” button resets all pa- rameters to the factory settings.

The “Lock” selection option blocks switching the cir-cuit breaker off or on from the software. As soon as the function is set to status “OFF”, the cir- cuit breaker can be switched. As soon as the circuit breaker is switched off from the software, the hard-ware LED at the channel shows the colour orange.

Attention:
The role of the logged in account has to be checked. The differences between the Admin and the User mode are explained in chapter 4.1.3.4. In addition, the function for resetting a circuit breaker and switching it on and off is not available with a con-nected fieldbus interface. The PLC software has a higher priority. Furthermore, control and writing via the webserver can be deactivated via the PLC software (Configura-tion data of the CPC12 – Byte 0 Bit 0)!

Statistic
In the second field the values of minimum and maxi-mum current and voltage of the selected circuit breaker are listed.In addition, calculated values for the average value in each case are listed. (No admin rights needed).
