Setting up I/O keyence IO module.

Ive been fighting for 3 days getting Keyence NQ-MP8L to work. After talking with them they are saying I need to do some sort of conversion in Unilogic to get the results I want. 

I have 5 of their modules that I'm just trying to read Digital Inputs from. When I set them Up with the EDS file it sets up as UINT16 instead of Bit. It stores it in my IO tab and populates the following values. IData_1_0 with 128

IData_1_1 with 418

IData1_2 with 21845

I get readings off it because my values change depending on what input I gain or lose. 

 

This is my first time using Unilogic and I'm just not seeing how I convert those values to simple Input readings. When I use the EDS file it grays out the Input tag option. So I'm not able to put them in the premade structures.

You're not giving us the background on what you're expecting.  You have 5 modules but you're not telling us what's connected to what port and whether it's on or not.

It looks like it's stacking the inputs as bits in a 16 bit word.  Word 0 with value decimal 128 translates to a bit pattern of 1000 0000.  Do you have more information (like a bitmap in the EDS file) that may translate this for us?

In the end, you'll need to map the UINT16 to a bit array to access the individual bits.  Create a two byte Buffer array tag and use the Tag->Buffer instruction to load it, then create a 16 element bit array and use the Buffer->Tag instruction to copy the bits from the Buffer to your bit array.

I was able to get it working Unitronics support suggested I use a NUM to BIT function. 

The problem resided in that I was not able to change the Input tag to the structure that was created because it being greyed out. So, I had to put the function command in to change it over from UINT16 to Bits so I could read the inputs from sensors more clearly.

Previous programs were done straight from the scanner and the input tag was the structure itself. Only way I had that option was to put the scanner data in manually instead of through an EDS file but every time I did that the PLC would no longer receive data at all from the IO module or to the valve stacks. Both modules and valve stacks would throw a flag that there was no communication to them even though the PLC was able to ping them.
