：
a.
When GW-7557 receives a “data output command” (output byte 0) from
system setting module, and this command didn’t increase in order (ex: 0->1,
1->2,…, 255->0), the GW-7557 will think that it lose some output data of the
PROFIBUS Master and a diagnostic message (“Lose PROFIBUS output
data”) will be sent by the GW-7557 to the PROFIBUS master.
b.
When GW-7557 receives a “HART channel” (output byte 3) from system
setting module, and this value is greater than 3, then a diagnostic message
(“Output Channel out of Range”) will be send by the GW-7557 to the
PROFIBUS master.
c.
When GW-7557 receives a “Preamble length” (output byte 4) from system
setting module, and this value is less than 5 or greater than 20, then GW-7557
will set preamble length to 20 automatically and a diagnostic message
(“Preamble length out of Range”) will be send by the GW-7557 to the
PROFIBUS master.
d.
If HART Frame Format is “Compact”. When GW-7557 receives a “Output
module” (Output byte 2) from system setting module, and “Output Mode” of
this module isn’t manual, then a diagnostic message (“Output Mode is not
Manual mode”) will be send by the GW-7557 to the PROFIBUS master.
e.
If GW-7557 detect burst frame at a certain HART channel. When user wants
to send HART command from this channel, then a diagnostic message
(“Burst Frame On HART Bus”) will be send by the GW-7557 to the
PROFIBUS master.
f.
GW-7557 just allow only one burst module (Output Mode is Burst). If the
number of burst modules are more than one, then a diagnostic message
(“Burst modules too much”) will be send by the GW-7557 to the PROFIBUS
master.
g.
If HART Frame Format is “Transparent”, user just can select Output length
module or Input length module; If HART Frame Format is “Compact”, user
just can select HART Command module; When user select wrong module,
then a diagnostic message (“Choose Wrong Module”) will be send by the
