1.4.2 SOFTMASTER
SOFTMASTER is software tool dedicated for the communication module including Pnet I/F module.
Setting the basic parameter, writing the frame and network diagnosis are available for the
communication module. Fore more detail, refer to Ch5. SOFTMASTER.
The following figure is an initial screen of the SOFTMASTER
[Figure 1.4.1] SOFTMASTER initial screen
1.4.3 Checking the version
Before using the Pnet I/F module, check the version of the module
(1) Check through the SOFTMASTER
This is method reading the communication module information through online connection
If it is under normal interface with the CPU, you can get the information as follows.
a) Execute the SOFTMASTER
b) Connect to the CPU through “Connect”on the “Online”menu.
c) After connection, execute [Online]-[Communication module setting]-[System Diagnosis]
d) In the “System Diagnosis”screen, select “Module Information”by double-clicking the
communication module and pop-up window
e) Software information appears at the right-bottom.

Note
1) IEC (International Electrotechnical Commission):
An international nongovernmental organization which promotes internationally cooperated standardization in
electric/electronic field, publishes international standards and manages applicable estimation system related with.
2) Pollution degree:
An index indicating pollution degree of the operating environment which decides insulation performance of the devices.
For instance, Pollution degree 2 indicates the state generally that only non-conductive pollution occurs. However, this
state contains temporary conduction due to dew produced.
