Hello,
I am working on a LabVIEW driver Programm for a DC load device. But during the test with HW, I am always getting the 0x8507 Error (write single coil Access denied),when I tried to set the device into remote mode from LabVIEW.
I have checked on the device display,
-'Allow remote control' is activated.
-Window for configuring IP is also closed.
Does anyone have an idea, what could be wrong? Any suggestions?
Thank you in advance.
Solved! Go to Solution.

Judging by the error (write single coil Access denied) I am guessing your device uses Modbus. Are you sure you are writing the right coil? Some a read only some are read/write...
We are going to need to see your code and probably know what make and model DC load you are using to offer any real advice.

Hello,
sorry, I didn not get time to upload my code yet. Now you can find it in the attachment.
Actually I have just made some modification from the driver examples provided by the producer. My DC Load is EPS ELR 11000-80-HP.
The error comes in the step of writing 'set remote mode' . Unfortuanately I don't have the access permission to the code of the subVI.

Hey, I have solved the problem. I found out today, that my colleague has connected the cable in a wrong way. It should be connected via an ABCC-EIPT module, not directly in LAN.
Thank you anyway.
