7.6 Multiple Units in a Network (Multidrop Mode)
Up to 32 units can be connected within a RS485 two-wire loop, see section 4.6
page 32. To direct a command to one unit among the 32 possible, it is necessary to „address" a
command. Therefore, a 3-digit number is set prior the command. The 3-digit number is determined
between 001 and 032.
XA=024
will set address to 24 (unit must not be in multidrop mode)
Changing an address:
(e.g. the address is change from 17 to 24)
Command
Answer
„017?E"
„017E0.950"
„017XA=024"
"017XA024" setting of a new address
„024?E"
„024E0.950"
Exception: Broadcast command. If a command is transferred, starting with the 3-digit number 000, all
units (with addresses from 001 to 032) connected will get this command – without to send an answer.
A unit with the address 000 is a single unit and not in multidrop mode.
Command
Answer
