Value
Meaning
REG_RD_DATA
0...
(2
32
-1)
Content of the register to be read if REG_RD_ABORT = 0. If
REG_RD_ABORT = 1, then REG_RD_DATA = 0.
REG_RD_ABORT 0
The reading of the register stated at REG_RD_ADR was
accepted and executed. The content of the register is located
in the user data range (REG_RD_DATA Bytes 0-3).
1
The reading of the register stated at REG_RD_ADR was not
accepted.The user data range (REG_RD_DATA Bytes 0-3) is
zero.
REG_RD_ADR
0...63
The reading of the register stated at REG_RD_ADR was not
accepted.The user data range (REG_RD_DATA Bytes 0-3) is
zero.
REG_WR_ACEPT 0
The writing of user data for process output to the register with
the address stated at REG_WR_ADR in the process output
data could not be executed.
1
The writing of user process output data to the register with
the address stated at REG_WR_ADR in the process output
data was successfully completed.
REG_WR_AKN
0
No modification of the data in the register bank by process
output, i.e. REG_WR = 0.
A write job would be accepted with the next telegram of
process output data. (handshake for data transmission to the
register.)
1
A modification of the register contents by a process output
was initiated, i.e. REG_WR = 1.
A write job would not be accepted with the next telegram of
process output data.
SSI_STS3
0
These four bits transfer the status bits of the SSI encoder with
the status messages of the SSI module. With some SSI
encoders, the status bits are transferred together with the
position value.
1
SSI_STS2
0
1
SSI_STS1
0
1
SSI_STS0
0
1
STS_UP (LED UP) 0
The SSI encoder values are decremented or the values are
constant.
1
The SSI encoder values are incremented.
