14.2.4 Defining configurations via the PLC-specific software
General prerequisites:
• The measuring light curtain has been mounted (see chapter 6) and connected (see chapter 7) cor
-
rectly.
• The basic configuration has been performed (see chapter 8).
• RS 485 Modbus-specific basic configurations have been performed.
• Slave address selected
• Bit rate selected
• Parity selected
• Silent interval entered
Open the configuration software of the RS 485 Modbus interface module.
Configure the following configuration parameters:
- Operating mode (parallel-beam; diagonal-beam; crossed-beam scanning)
- Blanking settings
- Teach settings
Perform a teach. This is possible via the receiver control panel or the control group in the
RS 485 Modbus process data.
If necessary, configure additional parameter/process data (see chapter 14.3).
Save the configuration via the control group in the RS 485 Modbus process data.
Saving ensures that the configuration is stored in non-volatile memory. Configurations that are not
stored in non-volatile memory have only temporary effect and are lost when the device is switched off.
The RS 485 Modbus-specific configurations have been performed, copied to the CML 700i and the
CML 700i is ready for process mode.

To configure the CML 700i, the user must set the parameters via RS 485 Modbus telegrams with
read/write commands (see chapter 14.2.1/see chapter 14.2.2).
Information on using the configuration parameters can be found in the general descriptions of the
individual functions of the CML 700i (see chapter 4).
