Data type Description
ARRAY[0..63] Image of the current configuration
OF WORD data
(CDI = Configuration Data Image)
ARRAY[0..63] Image of the projected
OF WORD configuration data
(PCD = Projected Configuration
Data)
ARRAY[0..31] Input parameters of the S/A slaves
OF BYTE
ARRAY[0..31] Input parameters of the B slaves
OF BYTE
Output parameters of the S/A
OF BYTE slaves
ARRAY[0..31] Output parameters of the B slaves
OF BYTE
Possible values
One word is available per slave:
Bits 0...3 = IO code
Bits 4...7 = ID code
Bits 8...11 = Extended ID1 code
Bits 12...15 = Extended ID2 code
→ DS11 – Actual configuration data
(CDI)
Each word contains data of one slave:
Bits 0...3 = IO
Bits 4...7 = ID
Bits 8...11 = ID1
Bits 12...15 = ID2
→ DS12 – Projected configuration data
(PCD)
Each byte contains parameters of one S/A
slave:
Bits 0...3 = P0-P3
Bits 4...7 = reserved
→ DS13 – Image of the input
parameters of the slaves (PI), words
0...15
Each byte contains parameters of one B
slave:
Bits 0...3 = P0-P3
Bits 4...7 = reserved
→ DS13 – Image of the input
parameters of the slaves (PI),
words 16...31
Each byte contains parameters of one S/A
slave:
Bits 0...3 = P0-P3
Bits 4...7 = reserved
→ DS14 – Image of the output
parameters of the slaves (PP), words
0...15
Each byte contains parameters of one B
slave:
Bits 0...3 = P0-P3
Bits 4...7 = reserved
→ DS14 – Image of the output
parameters of the slaves (PP), words
