Chapter 3 Configuring and Setting a PLC System
After is clicked, all the PLC parameters will be uploaded. After is clicked, the Transfer
Setup window will appear. Users can select parameter types which will be downloaded in the
window. Not all parameter types need to be downloaded to the CPU module.
The Transfer Setup window is shown below. If the CPU checkbox or the Ethernet─Advance are
selected, the CPU module must stop running during the downloading of the parameters. As a result,
if the CPU module does not stop running, a dialog box will appear before the parameters are
downloaded.
*1. If the name of the CPU module is different from the name attached to the model in the project management area,
a dialog box will appear before the parameters are downloaded or uploaded. Please refer to section 3.3.2.1 for
more information.
*2. HWCONFIG adopts the communication setting in ISPSoft. Please make sure that ISPSoft is connected to the CPU
module normally before the parameters are downloaded/uploaded. Please refer to section 2.4 for more
information.
3.4 Setting the Parameters in an AH500 Series Module
3.4.1 Managing the Version of a Module
The functions of a module or the parameters in the module vary with the versions of the module. In
HWCONFIG, the functions of the modules and the parameters in the modules are defined in a
document called MDS. When ISPSOft is installed, the latest MDS document is also installed. If a
new version of the MDS document is released, users can download it or get the related file from an
agent.
An MDS document provides the information about the firmware versions of the modules. If users
want to configure modules in HWCONFIG, they can select a suitable configuration according to the
firmware versions of the actual modules. Besides, the parameters which can be set in the modules
vary with the firmware versions of the modules which are set. If the firmware version of a module set
in HWCONFIG is older than the firmware version of the actual module, the module will operate
normally after the parameters are downloaded. If the firmware version of a module set in
HWCONFIG is newer than the firmware version of the actual module, the module will not operate
normally after the parameters are downloaded. Please refer to the descriptions in the table below for
more information.
Difference
Compatibility
The firmware version set is
older than the actual
firmware version.
The firmware version set is
newer than the actual
firmware version.
The module operates normally. Functions or parameters not
defined in HWCONFIG are assigned the default values.
The module can not operate, and is in an erroneous condition.
Users have to select a firmware version which is the same as the
firmware version of the actual module in HWCONFIG, check the
parameters, and download the parameters again.
*. The compatibility mechanism described above only applies to modules whose firmware version is 1.0 or above. A
firmware version below 1.0 is not compatible with firmware version 1.0 or above.
If users want to set the firmware version of a module, they can select a version number in the
Firmware Version drop-down list cell on the information list. If the firmware version of a module is
unknown, no version number will be displayed.
