We are using E3 version 4.8 with the Modbus Driver released in May19.
E3 Scada and third party HMI are polling multiple instruments in a modbus communication bus.
RS485 Data from Instruments is getting transferred to Scada and HMI vis RS485 to Ethernet Convertor (Multimaster).
Ethernet and TCP/IP are the configurations done in a modbus driver.
In the log file of Scada it is found that the response is being missed out frequently from the Instruments.
Only Scada works completely fine.
Only HMI works completely fine.
We tried VB.net make Scada with HMI and the application worked completely fine.
In case of Scada and HMI together, data is being missed in Scada.
Also, it has been mentioned that Modbus RTU is not to be selected in case of Ethernet application as per
KB -36523. If we use universal free Modscan32 software, there are settings related to inter frame delay which is not getting reflected in E3 driver in case of Ethernet/TCP/IP communication.
Is there any way out that we can do these settings in the Modbus driver and inter frame delay can be controlled for query response.
Please guide me for any other settings that needs to be done in the driver which we might be missing.
Silence on error is enabled too.
Thanking you in advance.
