IR n+2.04 Not used by C200HW-PRM21.
IR n+2.05
IR n+2.06 P-DP H/W failure
0: No error
1: Malfunctioning of the PROFIBUS-DP hardware.
The ERR LED is ON to indicate a fatal error, no communica-
tion over PROFIBUS.
IR n+2.07 Wrong CPU Unit.
0: No error
1: The Unit is mounted to a PLC type which does not support the
C200HW-PRM21.
The ERR LED is ON to indicate a fatal error, no communica-
tion over PROFIBUS.
IR n+2.08 DM setting error (exceeding maximum number of words).
0: No error
1: The input/output area mapping, defined by the Unit's DM
settings, exceeds the maximum allowed number of words
(300 words for all PLC's, except C200HS: 80 words).
The ERR LED is ON to indicate a fatal error, no communica-
tion over PROFIBUS.
IR n+2.09 DM setting error (output area mapping)
0: No error
1: There is an error in the output area mapping.
The mapping contains an incorrect value for either:
- the start address in the output buffer in the Master,
- the start address of the output area(s) in the PLC,
- or the size of the output area(s),
or the specified size makes the area(s) exceed the boundaries
of available buffer, DM, LR, IR or HR areas.
The ERR LED is FLASHING to indicate a non-fatal error; no
data is transferred from the output area(s) afflicted by the
setting error(s).
IR n+2.10 DM setting error (input area mapping)
0: No error
1: There is an error in the input area mapping.
The DM settings contain an incorrect value for either:
- the start address in the input buffer in the Master,
- the start address of the input area(s) in the PLC,
- or the size of the input area(s),
or the specified size makes the area(s) exceed the boundaries
of available buffer, DM, LR, IR or HR areas.
The ERR LED is FLASHING to indicate a non-fatal error; no
data is transferred from the output area(s) afflicted by the
setting error(s).
