Modbus in Zabbix 6.2

[IPTC]

Hi,

I've recently been testing Zabbix 6.2 version, but I can't get data from my modbus devices as I used to in Zabbix 4.4.

From the 4.4 version I have the following request key:

modbus_read[enc://{$MODBUS_IP}:{$MODBUS_PORT},{$MODBUS_SLAVE},0,3,8* uint16]

For the 6.2 version and reading the documentation on Modbus, it states the following:

"Possible protocol values: rtu, ascii (Agent 2 only), tcp" does this mean I wont be able to get information from a device that uses modbus encapsulated over tcp?

The key is also a bit diferent and I've build the following request key for the 6.2 version:

modbus.get[enc://{$MODBUS_IP}:{$MODBUS_PORT},{$MODBUS_SLAVE},0,3,8* uint16]

I get the "unsupported item key" from my request.

I really need to get these devices readings to upgrade my Zabbix version.

Thanks.

Maybe stupid question, but what does the "tcp" protocol do then if it is not "encapsulated over tcp"?

I don't see modbus_read item in the Zabbix 4.4 agent, so what was that?

modbus.get[] is an agent item in 6.2.
