PACIO MODULES
140 Parker Automation Controller Installation Guide
With the setting of the bit "SetOptions", the assumption of the address in the Module becomes released.
The Module acknowledges the assumption of the address by setting of "OptionsSet".
After receipt of a valid PROFIBUS address, the Module initializes the PROFIBUS. If a master accesses the
Module over the PROFIBUS and transfers a valid configuration, the professional bus is functional. This is
indicated by the bit "ProfibusRunning".
Only then data exchange EtherCAT <- -> PROFIBUS is possible.
Since revision 2, the address change at runtime is possible. The connection with the PROFIBUS master
will be cut for a short time, but the master will rebuild the connection to the new address by its GAP
update. The status of the connection is shown in "ProfibusRunning".
Example:
Setting of usiDP_Address as DP-Slave address
(* Start (Single action) *)
Term2_Address:=usiDP_Adresse; (* Copying the DP-Slave address *)
Term2_SetOptions_Byte.0:=TRUE; (* Start of the address setting *)
(* Controlling*)
IF Term2_SetOptions_Byte.0=TRUE THEN
IF Term2_Shortcut_Byte.7=TRUE THEN (* Wait for confirmation *)
Term2_SetOptions_Byte.0=FALSE; (* Reset*)

PROFIBUS example with Siemens S7
This document outlines the procedure for configuring ProfiBus communication from PAC to a Siemens S7
processor capable of communicating this protocol. This particular configuration demonstrates this using
the Siemens CPU 315-2 PN/DP 6ES7 315-2EH13-0AB0 / V2.6 processor and STEP 7 v5.4 SP5 software.
