Hello,
I have a question about the wiring of siemens io cards:
6ES7331-7NF00-0AB0- does this card only support 2 wire instruments with an external supply as shown on page 310 of the manual or can a 2 wire transmitter be connected straight to its terminals eg across 4 and 5?
6es7321-1bl00-0AA0
With regards to channel number of this card does this run 0-7 four times? Eg if an input is connected to terminal 3 and terminal 23 are these both channel 1? As is shown on page 70 of the manual.
Thank you.
