TS4000H
5.7.2 Exception Code
Exception Code Field:
In a normal response, the TS4000H returns data and status in the
response data field. In an exception response, the TS4000H returns an exception code
(describing the TS4000H condition) in the data field. Below is a list of exception codes that are
supported by the TS4000H:
Code Name Description
1
Illegal Function
The function code received in the query is not an allowable
action for the TS4000H.
2
Illegal Data Address
The data address received in the query is not an allowable
address for the TS4000H.
3
Illegal Data Value
A value contained in the query data field is not an allowable
value for the TS4000H.
4
Slave Device Failure
An unrecoverable error occurred while the TS4000H was
attempting to perform the requested action.
5
Acknowledge
The TS4000H has accepted the request and is processing
it, but a long duration of time will be required to do so. This
response is returned to prevent a timeout error from
occurring in the master.
6
Device Busy
The TS4000H is engaged in processing a long-duration
program command. The master should retransmit the
message later when the slave is free.
