comprises:
1. Description of the RS485-
interface
You can, via the RS232 interface of a industrial computer
and an RS232-RS485 bus converter, communicate with up
to 31 COMPAX devices. The following functions are
supported:
!
direct command input and execution in on-line mode,
!
reading out status values,
!
reading and writing program blocks (full command set
available),
!
reading and writing parameters, and
!
transmission of control statements.
Interface parameter of the ASCII protocol:
Interface: F1: 4 wire for RS232-master
via RS232/RS485 -
converter.
