Channel-specific error for channel 1:<br />

Assignment corresponds to channel 0,<br />

see byte 8<br />

If a HART channel error occurs, you can obtain further information by<br />

using SFC59 to read the status in the HART response data record for the<br />

relevant client (see Section 4.8.3 ) or the additional diagnostic data record<br />

for the relevant channel (see Section 4.8.4).<br />
