7.24.1 Testing Communication Interfaces
If communication interfaces are installed in the off-grid inverter, test that they have been installed
correctly as follows:
1. Switch to installer mode (see Section 7.5).
2. To test the installation of the SI-SYSCAN.BGx Multicluster communication interface, select the
312.15 ComMod1 parameter and read off the value.
☑ The value is SI-SysCan.
✖ Is the value ‒‒‒?
The communication interface is not plugged into the interface slot correctly.
• Ensure that the communication interface is plugged into the SISysCan interface slot.
• Ensure that the communication interface has been installed correctly
(see the SI-SYSCAN-NR mounting instructions).
3. To test the installation of the RS485 SI-COMSMA.BGx communication interface, select the
312.16 ComMod2 parameter and read off the value.
☑ The value is SI-ComSma.
✖ Is the value ‒‒‒?
The communication interface is not plugged into the interface slot correctly (see the mounting
instructions for the communication interface).
• Ensure that the communication interface is plugged into the SiComSma interface slot.
• Ensure that the communication interface has been installed correctly
(see the SI-COMSMA-NR mounting instructions).
