Siemens/ASI help

[DLMUK]

Hi,

I have a customer who would like to add four of our analogue load cells (0-50mV output range) to their ASI network. The customer I don't think supplies the ASI components, another company sets up the controls.

I have never done anything with ASI before, I understand the basics but am after a bit more help.

1) Are ASI components compatible cross manufacturers like RS485? I.e. can I have a Siemens I/O block communicating with a bihl master? Or similar.

2) Looking on TIA portal under the Field Devices there is a whole array of options. What I would like to do ideally is plug my load cells into a PLC to store calibration and other items etc, and then provide an ASI output to a master PLC.

Any help would be great - thanks!

I am not an ASI master, but I know a bit.

Yes.

This is not clearly formulated.
It is not described who is the ASI master, your PLC or the master PLC.
Do you intend to provide an output on the ASI-bus for the master to read as an analog signal. I.e. a 4-20 mA signal. That should be doable. But does not make much sense to go via ASI to achieve that.
Or do you intend to provide a signal that the master can read via an ASI analog input. That is doable, you dont even need a PLC. Any loadcell converter that can output 4-20mA can do that.
Or do you intend to create a data transfer over the ASI bus from one CPU to another CPU ? That is not possible. ASI is not a multi-master bus.

Reading this again, I think you want to find a loadcell module that is an ASI slave.
As far as I know there is no such thing, at least not from Siemens. ASI slave types are relatively few. Mostly digital i/o and analog as Pt100 or 4-20mA.
