Examples
Configuration of the valve batteries with extension battery (ies)
- byte-by-byte composition of the inputs and outputs
The settings of the desired configuration, i.e. the setting of different identifiers, is generally done with the
aid of the GSD file. Up to 18 identifiers (slots) may be allocated.
Each extension battery begins with a new byte in the process map. For the main battery and each
extension battery, 2 identifiers are used, i.e. in the case of byte-by byte configuration, the identifiers of
one valve batteriy must be connected.
Each valve battery can be configured with 4 input bytes and 3 output bytes. If no inputs or outputs are
present on a valve battery, the identifier 0 (blank) is entered.
Manual configuration
If no GSD file is available, manual configuration must be performed. The following data apply.
The identifiers are built up as follows:
Bit 7 Bit 6 Bit 5 - 4 Bit 3 - 0
Consistency
0 = Byte/Word
1 = entire length
Bytes / Words
0 = Bytes
1 = Words (2 Byte)
Input / Output
00 = special identifier format
01 = input
10 = output
11 = input/output
Length (number of data)
0000 = 1 Byte / Word
:
0010 = 3 Byte / Words
:
1111 = 16 Byte / Words
