n = offset of input data; depending on extension of station and the corresponding fieldbus.
Meaning of the data bits (process input)
Designation Value Description
SSI_DIAG 0 No enabled status signal is active (SSI_STSx = 0).
1 At least one enabled status signal is active (SSI_STSx = 1)
ERR_SSI 0 SSI encoder signal present.
1 SSI encoder signal faulty. (e.g. due to a cable break).
STS_OFLW 0 A comparison of the register contents has produced the following
result: (REG_SSI_POS) (REG_UPPER_LIMIT)
1 A comparison of the register contents has produced the following
result: (REG_SSI_POS) > (REG_UPPER_LIMIT)
STS_UFLW 0 A comparison of the register contents has produced the following
result: (REG_SSI_POS) (REG_LOWER_LIMIT)
1 A comparison of the register contents has produced the following
result: (REG_SSI_POS) < (REG_LOWER_LIMIT)
ERR_PARA 0 The parameter set of the module has been accepted.
1 Operation of the module is not possible with the present parameter
set.
STS_STOP 0 The SSI encoder is read cyclically.
1 Communication with the SSI encoder is stopped as STOP = 1 (process
output) or
ERR_PARA = 1.
STS_CMP1 0 A comparison of the register contents has produced the following
result:
(REG_SSI_POS) (REG_CMP1)
1 A comparison of the register contents has produced the following
result:
(REG_ SSI_POS) = (REG_CMP1)
FLAG_CMP1 0 Default status, i.e. the register contents have not yet matched
(REG_SSI_POS) = (REG_CMP1) since the last reset.
1 The contents of the registers match (REG_SSI_POS) = (REG_CMP1). This
marker must be reset with CLR_CMP1 = 1 in the process output data.
REL_CMP1 0 A comparison of the register contents has produced the following
result:
(REG_SSI_POS) < (REG_CMP1)
1 A comparison of the register contents has produced the following
result:
(REG_ SSI_POS) (REG_CMP1)
STS_CMP2 0 A comparison of the register contents has produced the following
result:
(REG_SSI_POS) (REG_CMP2)
1 A comparison of the register contents has produced the following
result:
(REG_ SSI_POS) = (REG_CMP2)
