Hi All,
I have wired up plenty of sensors and plenty of digital things over my time. However my exposure to analog cards and sensors is very limited, but I have done it.
However it isnt working. I confidently told the customer to order the parts and thought I could sort it, but I just cant get a value out of the device...
Maybe I am just being thick.
I have an LKM445 sensor and connecting to a 6ES7134-6HB00-0CA1 on a 1516 PLC.
Set it up as a 2 wire 4-20ma transducer as per the attached screenshot. Wired up the +24VDC terminal on the sensor terminal 5 of the input card and the T+ terminal to terminal 9 of the input card. I get absolutely nothing, I get wire breaks, no scaling or anything works out.
Any ideas that I can try? I have tried an external 24vdc+ supply to the sensor. Changing every setting around 4-20ma 2 wire in TIA... I think I just dont understand the principles.
