I have a FP-1600 and a FP-AO-200 module, 0-20 ma. When I use Field Point Explorer 3.0.1, I can not command any of the channel output current. The current remains in the lowest value 0.0035 A. What is the problem ?

I have a FP-1600 and a FP-AO-200 module, 0-20 ma. When I use Field Point Explorer 3.0.1, I can not command any of the channel output current. The current remains in the lowest value 0.0035 A. What is the problem ? The communications with the module are OK, because it shows when the current are open or closed.

Jorg,

I noticed that you claimed to be using the module in 0-20mA mode, yet the reading you are seeing is 3.5mA. This is the minimum value (with overranging) when the module is set to 4-20mA mode. My guess is that your module is defaulting back to 4-20mA mode, but your IAK file still thinks the module is in 0-20mA mode. You can verify this by using the find devices button in FieldPoint Explorer and then trying to write to the channel.

To fix this problem, you should use the snapshot feature to change the default power-up mode for that channel.

Jorg,

What are the country settings on your computer? Certain country settings set the decimal to be a comma. Thus if you are trying to write 0.015 to output 15 mA, FieldPoint may be interpreting it as 15 A and refusing to change the output since it is out of range.
