Table 10-4 Scenario 3: SCK-C-MODBUS

Device/error description Status register LED indicator

SCK-C-MODBUS (2901674)

There is no data or incorrect data from

one or more connected measuring

modules.

Entry “1” in bit 6 of the

low byte (0100 0000)

POWER LED:

flashing (1.4 Hz)

and/or Tx LED lights

up sporadically

Cause

Data transmission to the affected measuring module is faulty.

Measures

1. Check the shielding and installation of the affected SCK bus data cable (see Section

“Data collection in large photovoltaic systems” on page 15 and Section “Cabling” on

page 44).

2. Remove any interference couplings.

3. After removing the error cause, test the function of the affected device.

4. If the message is still present:

a) The connection is still faulty or disrupted  see item 1

or b) Internal components have been damaged In this case, replace the communica-

tion module.

5. For closer examination of the data quality, it is recommended that you record the sig-

nals on the SCK BUS cable using an oscilloscope.

Table 10-5 Scenario 4: SCK-C-MODBUS

Device/error description Status register LED indicator

SCK-C-MODBUS (2901674)

There is no data from one or more con-

nected measuring modules.

Entry “1” in bit 7 of the

low byte (1000 0000)

POWER LED:

permanently ON

Cause

The affected module or measuring modules connected to it have been switched off by the

energy-saving function.

Measures

1. If shutdown was not planned, check the source text of your program and remove the

setting for the energy-saving function (see Section “Energy-saving mode” on

page 65).

2. After disabling the energy-saving function, test the function of the affected module. If

it remains switched off and the register entry is set to “0”, an error has occurred. Send

in the device.
