PROFI-8455 – Setting and Module Installation
The following steps can help users to set and apply the PROFI-8455.
1. Load GSD file into the DP-Master Configuring software
DP-Master
configuring
software
(Siemens
Step7
or
ProfiCaptain etc...) loads IPDS0B0C.gsd file, and make sure of
the “PROFI-8455” label in “I/O” category. Finally, Loading
PROFI-8455 into PROFIBUS at the software and activate it.
2. Select I/O modules
Choose PROFI-8455 and add I/O module that you want to use.
Modify the system parameter “WD_On”, “Freeze/Sync Req.”,
“Lock/Unlock Req”, “Group-ID assignment”, etc… (modify by
user’s preference)
3. Set Parameter Data
Wait parameterization is an important step before data
exchange. In this stage, DP-Master provides the essential
parameter to PROFI-8455 include user parameters and module
parameters. Therefore, it must finish this setting before data
exchange.
1. User Parameter
:
“User parameter” also called “system parameter” is the basic
parameters. The number of parameter is fixed regardless of the
number of modules. In PROFI-8455, there are two kinds of
parameter. They are Byte Order and Diagnosis Repot Period.
Byte-Order Parameter:
If your system obeys the INTEL
data format, you should select Little-Endian mode; otherwise,
you should select Big-Endian mode.
Diagnosis Report Period Parameter:
This parameter
dominates the time interval of each diagnostic message report.
The unit of this period is millisecond. The maximum time
interval is 65536 ms, the minimum is 0 ms.
2. Module Parameters:
The most of modules must be initialized before applying
them. Module parameters provide information about Operation
Code, Data Code or Enable Diagnosis, etc… Please refer to the
manual to know more information about these parameters.
4. Download Setting and Program into DP-Master
Users load the setting and program into DP-Master, and let it
go.
Users must finish these steps before starting to communicate with
PROFI-8455.
