1. For instance, in RSLogix500, we have Analog Address as say I:0.0 storing Float data in register say F8:0,
In CLICK Software is it perfect to say Analog Address as AD1I (for first current channel)storing data in DF1
2. Do they have a Simulator for this CLICK Software
3. What software is used for HMIs compartible with CLICK Ethernet Analog PLCs?
The above post will show you how to address the analog card on the Click PLC.
Here is a link for the entire series on the Click PLC. http://accautomation.ca/series/click-plc/
The CMore EA7 family (obsolete) does NOT include a tag-based comms driver for the CLICK. You would have to go full-strength modbus addressing in the EA7.
The Tag Database (Address Picker) can be coerced to display the Modbus register/coil addresses.
I like Red Lion HMI for use with the Click (or any other PLC). Their Modbus driver handles word swapping and byte swapping nicely and can deal with all manner of protocol limitations and variations.
