The I/O example program can also be used as an example for the two methods
of configuration "Configuration by Master" (ForceMasterConfig) and
"Configuration by Controller Application" (ForceUserConfig). The configuration
array of the sample project is pre-initialized with following values:
Configuration
word Data
type Low/High
Byte Description Configured
values
Explanation
LOW Byte Busaddress 2 This address will be active if the
rotary switches of the module are
adjusted to "00" 0 INT
HIGH Byte Force User
Configuration 0 0 = ForceMasterConfig
The module will take over the
configuration from the master.
1 INT Reserved
2 INT Watchdog Timeout C8h (200dec) Watchdog 200 ms
3 INT Number of valid config
bytes
(starting with
Local:1:C.Data[8]) 8 8 Bytes of the module definition
array are valid
4 INT Reserved
5 INT Reserved
6 INT Reserved
7 INT Reserved
LOW Byte Module 1 Type 4 Module 1 Type:
Input Byte with consistency 8 INT
HIGH Byte Module 1 Length 3 Module 1 Length: 4 (byte)
LOW Byte Module 2 Type 5 Module 2 Type:
Input Word with consistency 9 INT
HIGH Byte Module 2 Length 1 Module 2 Length: 2 (word)
LOW Byte Module 3 Type 6 Module 3 Type:
Output Byte with consistency 10 INT
HIGH Byte Module 3 Length 3 Module 3 Length: 4 (byte)
LOW Byte Module 4 Type 7 Module 4 Type:
Output Word with consistency 11 INT
HIGH Byte Module 4 Length 1 Module 4 Length: 2 (word)
... ...

LOW Byte Module 24 Type 0 31 INT
HIGH Byte Module 24 Length 0
The parameter "ForceUserConfiguration" is initialized with 0. If you want to
activate the pre-defined modules set this parameter to 1. When this parameter is
active the master configuration has to match exactly with this configuration
otherwise the slave will not start the communication with the master.
The parameter busaddress is independent from the parameter
"ForceUserConfiguration". This parameter will be active, if the rotary address
switches of the module are set to "00".
