Frequently Asked Questions (FAQs)
1. How do I format an address string when connecting to multiple
PLCs?
Add the PLC station number to the beginning of the address string. Ex:
PLC station is 3 and the address is V2000 the string would look like
this, 3-V2000.
2. Can I convert a project from one EZSeries Set Point Display Text
Panel type to another?
Yes, to do this simply change the panel type from one to another.
This will keep all address and message information intact. The only
exception is switching from any of the panels to the Set Point panel.
This will cause all messages and addressing to be deleted.
Note:
Switching panel types does not create a new project. If you wish to
create a new project select NEW from the FILE menu.
3. Can I connect multiple panels to a single PLC?
Yes, there are two methods of doing this. The fi rst would be to use the
multiplexer (P/N EZ-MULTIDROP). You can connect up to fi ve panels
per multiplexer, and one multiplexer per serial port. The second method
is to connect one panel per serial port.
