 Error Decode Byte
Bit
00 to 07 Error Decode
In case the Error decode byte is 128, i.e. PROFIBUS DP-V1, the Error code 1 byte can have the
possible values defined in the table below.
 Error Code 1 Byte
Error Class Code
0 to 9 Reserved
10 Application
11 Access
12 Resource
13 to 15 User Specific
 Error Code 2 Byte
This error code will always contain user specific error codes. If necessary, refer to the slave device's
documentation for decoding the returned byte.
CJ-series PROFIBUS Master Unit Operation Manual for NJ-series CPU Unit (W509)
The code determines the protocol type of the slave which returned the error code. Since this
error scheme can also be used in network applications containing protocol converters (i.e.
gateways), non-PROFIBUS protocols are also defined in this list.

Description
Description
Error codes related to the applica-
tion, i.e. the slave device it self or I/O
modules connected to this device.
Error codes related to accessing the
requested data area in the slave
device or I/O modules connected to
the slave device.
Error codes related to resources
inside the slave device which are
required to process the requested
data, e.g. functions required to
implement a requested action.
