Meaning Explanation
5 Response error Bit 0 = 1: GAP timeout
Bit 1 = 1: Receive buer overow
Bit 2 = 1: Timeout
Bit 3 = 1: Checksum error
Bit 4 = 1: Framing error
Bit 5 = 1: Overow error
Bit 6 = 1: Parity error
Bit 7 = 1: Reserved
6 Query rejected 0: Not specied
1: Short format (compact format) not supported
2: SHC not supported

4: No resources
5: Channel in standby mode
1
6 to 127: Reserved
128 to 255: Manufacturer-specic
7 Prole query rejected 0: Not specied (not supported)
8 Manufacturer-specic
query rejected
0: Not specied (not supported)

An external HART request was refused because the channel is not the active channel of a redundancy
pair. The request must be sent to the connected eld device via the partner module
Example of HART programming (HART command interface)
For the HART channel 0, the command 01 is to be sent in the transparent message format to the
HART eld device with the address "98 CF 38 84 F0".
A positive edge at input 4.0 of a digital input module leads to the writing of the HART command.
The following assumptions are made:
• The module address of the I/O module is 512 (200
H
)
• The data record is stored in DB80: starting from address 0.0, length of 11 bytes.
• The DB80 (request data record for channel 0) in this example consists of 11 bytes
