13.2.7 Response (ms)
This parameter operates in RTU or ASCII mode.
Select the line
Response(ms)
with the
keys and press OK.
Use the
keys to change the displayed value (response time in ms). The displayable values go
from
0
to
500
in steps of 50.
•
The response time, in milliseconds, is the time between when the RS485 frame has been received
and when the ENERIUM answers. This value should be set based on the number of ENERIUMs
connected to the RS485 line and the quality of the fieldbus.
•
NB: a response time set to 0 ms is not the real response time which is equal to the internal frame
processing time, approximately 35 ms. For the other values, the time set is the real response time.
Press OK to confirm.
Timeline of the communication exchange
Master
Slave
t1 = Request transfer time
t2 = Response time
t3 = Response transfer time
t4 = Turnaround time
t5 = Total response time
13.2.8 ASCII timeout (ms)
Select the line
ASCII timeout
with the
keys and press OK.
Use the
keys to change the displayed (timeout in ms) value. The displayable values go from
1000
to
10000
in steps of 1 ms.
•
The timeout in milliseconds is the maximum time allowed between the receipt of two ASCII
characters. If this is exceeded, communication is reset.
Press OK to confirm.
t1 = durée de transfet de la question
t2 = temps de réponse (le timeout est défini sur cette valeur)
t3 = durée de transfert de la réponse
t4 = temps de retournement (temps minimum avant de pouvoir poser une nouvelle question)
t5 = temps de réponse total (performance générale de l'esclave Jbus)
