"Protocol":
You set the communication protocol here:
●
MODBUS RTU
●
SEAbus
"Response time":
If the Power Monitoring Device communicates over the RS 485 bus with an older
MODBUS module from another manufacturer, it may be necessary to delay the response of
a slave to a request from the master. The response time corresponds to the set baud rate. At
baud rates ≥ 19200 bit/s, the response time corresponds to a character interval of at least
3.5 with regard to the configured baud rate.

Setting options
Setting
Meaning
0 = Auto
The device automatically sets a response time suitable to the baud rate. This is
the minimal response time.
1 ... 255
Response time in ms
If you change the baud rate to a value that does not suit the response time set, the program
sets the response time to "Auto".
