The I/O Data Channel
Function Set and actual values are exchanged between the controller and the
BK7500 via the I/O data channels. Set and actual values may be
exchanged either cyclically or non-cyclically.
The controller needs the I/O data base in order to address the I/O data
channel.
The set and actual values of a BK7500 are divided into the following types.
I/O terminal types Digital input terminals KL1xxx (without KL1501)
Digital output terminals KL2xxx (without KL2502)
Analog input terminal KL3xxx
Analog output terminal KL4xxx
Encoder terminal KL5xxx
Communication terminal KL6xxx
IDN Name Type Attributes Default
value
S-1-0000 I/O data base IDN Read/Write IDN: I/O base + 00000
Meaning This operating data contains the IDN of the first I/O data channel, i.e. the
IDN of the channel container for this I/O data channel. The controller reads
this value in order to calculate the IDN of the I/O data channel.
IDN Name Type Attributes Default
value
S-1-0001 Max I/O Channel Uint 16 Read/Write IDN: I/O base + 00001
Meaning This operating data indicates the maximum number of I/O data channels in
the BK7500.
IDN Name Type Attributes Default
value
S-1-0002 List I/O data channels Uint 16 Read/Write IDN: I/O base + 00002
Meaning The BK7500 writes the required I/O data channels with their absolute
addresses into this operating data.
IDN Name Type Attributes Default
value
S-2-0000 I/O data channel Uint 16 Read IDN: I/O data base + 0000
Meaning This operating data contains the IDN of the first I/O data channel. Observe
the mapping of the terminals!
