Subnet Status (5) Red Blinking

Anybus Support
#1

Hi All,

We have a problem that the Subnet Status (5) always Red blinking/Flashing . It make an impact that data from Inverter which connected to PLC become not real. Currently this anybus connected between Santerno Inverter (Modbus RTU) to WAGO PLC (Modbus-TCP).

Any suggest what i have check ? and how.

Thanks.

Hi @M_Komaruddin ,
This might depend on exactly what anybus device you have.

A flashing red LED 5 indicates a transaction error on the modbus RTU side. I would use the logging feature to take a log and look for a query that doent have a response or one with an error in it. You will need to analyse the log looking for an error response. See the explanation of modbus exceptions here: Exception Codes | Simply Modbus Software

For a more in-depth analysis I recommend opening a case on support.hms-networks.com

Hi @M_Komaruddin,

I looks like the log does not contain any errors based on the LED changed from green to red for a period I would guess a particular node or two are faulting. You could try stopping the logging immediately after it stops being red. Then check the logs for timeouts.

I ask that you open a case on support.hms-networks.com to get in touch with a support engineer in your local time zone.
