Configure the service control interface

Specify the interface to which the PLC is connected that controls the services, and set the station number of this PLC.

1. Go to COM Interface > Service control interface > COM interface to control device (PLC).
2. Set the FP-I4C interface that is used to poll control or status flags and registers.

   Example: To use the FTP client function, you must set an address range for control registers in the PLC. These addresses will be polled via the selected COM interface.

   Select INTERN if the internal memory of the FP-I4C unit is used instead of a PLC to control the services. The interface INTERN refers to the addressable internal memory areas of the FP-I4C unit which are accessible via Modbus/TCP or the script function.

3. For Station number of control device (PLC), set the station number of the connected control device.

   • Use the default setting 0 for RS232.

   • Set a number greater than 0 for RS485 and Ethernet. For Ethernet, the station number corresponds to the last octet of the IP address.

4. Save your configuration.

   When you have changed any settings, a Save button appears in the upper right corner of the screen. You can make changes on multiple pages and then save your settings.
