Cxh 80h 92h A type other than BYTE has been specified in an ANY reference.
Cxh 80h 93h The area identifier contained in the configuration (SDB1, SDB2x) of the logical address is not
permitted for these SFCs. Permitted:
•
0 = S7-400
•
1 = S7-300
•
2, 7 = DP modules and backplane bus
Cxh 80h A0h Negative acknowledgment when reading from module; Ident profile fetches acknowledgment although
no acknowledgment is ready
A user who is not using the Ident profile wants to fetch DS 101 (or DS 102 to DS 104) although no
acknowledgment is available.
•
Perform an init_run to resynchronize communications module and application
Cxh 80h A1h Negative acknowledgment when writing to the module; Ident profile sends command although a
communications module cannot receive a command
Cxh 80h A2h DP protocol error in layer 2 could be a hardware defect
Cxh 80h A3h DP protocol error in Direct-Data-Link-Mapper or User-Interface/User could be a hardware defect

•
SFC not possible for module type.
•
Data record unknown to module.
•
Data record number ≥ 241 is not allowed.
•
Data records 0 and 1 are not permitted for SFC 58 "WR_REC".
Cxh 80h B1h The length specified in the RECORD parameter is wrong.
Cxh 80h B2h The configured slot is not occupied.

Cxh 80h C1h The data of the preceding write job on the module for the same data record have not yet been
processed by the module.
Cxh 80h C2h The module is currently processing the maximum possible number of jobs for a CPU.
Cxh 80h C3h Required resources (memory, etc.) are currently in use.
This error is not reported by the Ident profile. If this error occurs, the Ident profile waits until the
system is able to provide resources again.
