Hi All,
I have just installed a micrologix1100 with a 1769 IF4 analog module connected, connected to channel 0 of the 1769 I have a 4-20mA / 0-16 Bar danfoss pressure transducer, the transducer is measuring around 7 Bar.
I have used a SCP instruction in my ladder but the value being displayed on I:1/0 (the 1st analog channel) is -57, I have checked the channel is configured for 4-20mA (in advanced I/O config) and is also set to raw data, and also that the DIP settings are on mA and not V.
I can't find any information on setting the module any further than I already have.
Starting from 'scratch', what is the raw data expected from a 4-20mA transducer measuring from 0 to its maximum ?
Thanks
Chris
