Watch time of response time over (Sec):
Set the monitoring time (0-9999 sec) from the start of transmission to a response.
Frequency of communication error (for determination of reduced
frequency):
When communication errors occur the number of times specified (0-9999 times),
the communication state of the MODBUS RAS information becomes erroneous.
Also, the communication frequency is reduced when communication errors occur
the number of times specified (0-9999 times).
Multiple at cycle (for determination of reduced frequency):
When the communication frequency is reduced, communication is performed at
the timing of the cycle of the user request parameter x the number of times
specified.
RS-232C DCD Signal diagnosis:
Set whether to perform diagnosis of the DCD signal when the transmission path is
RS232C.
RS-232C DSR Signal diagnosis:
Set whether to perform diagnosis of the DSR signal when the transmission path is
RS232C.
RS-232C CTS Signal diagnosis:
Set whether to perform diagnosis of the CTS signal when the transmission path is
RS232C.
