Ethernet
This form is to enter the IP address of the CRP, the Subnet mask and the Gateway IP-address to make the CRP accessible from inside and outside of the existing LAN.
In case the factory set IP address and Subnet mask do not fit with the existing LAN, it will be the easiest method to access the CRP for the first time by using the USB service cable AC3006. Once detected you may enter the appropriate IP address range, Subnet mask and Gateway address and the CRP will be detected via the Ethernet connector as well.
In case no USB service cable AC3006 is available to configure the IP address, there are some alternatives to access CRP:
- Via RS485 – for an easy setup make use of an AC3010 USB / RS-485 converter cable plus a device power supply. The default RS485 address is 0.
- Via Ethernet – an easy setup may be performed by means of an ethernet point-to-point connection from a laptop to the CRP. In this case please configure the laptop using a fixed address within the range of the default IP address of the CRP (only the last number of the IP address might be different). Afterwards reconfigure the CRP IP address as the IT structure requires.
Maintenance
The Maintenance Mode will be activated in case of maintenance services: Clean room cleaning, temporary removal/replacement of a probe for adjustment/calibration, during the adjustment/calibration process of a sensor, zero point correction and so on.
Click on the blue and underscored text to enable/disable the Maintenance Mode.
Maintenance mode informs the participating interfaces about ongoing modifications to the CRP. That is to say, if a customer makes an adjustment via the devices menu, the Maintenance Mode will be activated by HW5 and displayed. This also applies if HW4 configures a property with influence on the measured value.
