which Modbus Driver ? - Sungrow Logger 1000A

just closing this one out after a successful outcome with SCADA support yesterday.

the following ini file parameters were required to be added to get this specific device to talk. Note BOARD2_PORT46 is the Sungrow Logger 1000A device which was problematic

[MODNET.BOARD2_PORT46]
InitVar = 030001

Hi Alan, actually i'm getting same issue can you please suggest me that this parameter to be added in Citect.ini file of project or plant scada software? and which driver you have selected?

Hi Vishal,

yes i needed to add the parameter to the ini file "Specifically" for that device ONLY (i have other devices on Modbus TCP). the driver i used was MODNET for my comms. the issue with my device was the SCADA driver would not initialize the device i think , hence the parameter that must force a read of address 030001.

a free tool that i found handy for fault finding was "CAS Modbus Scanner" which could easily read the device. SCADA support also used "Wireshark" software to diagnose the SCADA driver issue.
