System - Mitsubishi Electric MELSEC iQ-R User Manual

System

Parameters for backup, logging, and reading cycle can be set in "System".
For the setting method, refer to the following section.
Page 279 Setting method
Item Description
Backup-Hour  (unavailable)
 (unavailable)
Backup-Minute
MaxComLogCount Set the maximum number of logs which can be checked with BACnet Communication within
the range of 100 to 10000.
SleepTime Specify an idling time (unit: milliseconds) from when all the values in the buffer memory are
read to when a value is read next time.
By lengthen the idling time, the load of the BACnet module is reduced. However, the
application of values takes time.
Taking the load of a BACnet module in consideration, 120 (milliseconds) is recommended.
Interface
Parameters for sequence programs and buffer memory can be set in "Interface".
For the setting method, refer to the following section.
Page 279 Setting method
Item Description
CheckYDevice Set whether to join/leave BACnet automatically.
1: A BACnet module joins/leaves BACnet automatically.
0: A BACnet module joins/leaves BACnet by a sequence program. (Page 250 Joining of
BACnet (Y1))
InitialDataOutputDisable Set whether to output the backed up PresentValue property value before powering OFF (or reset)
to the buffer memory or not at the start of the module.
0: The value is output.
1: The value is not output.
OutOfServiceControl Set whether to output the change of an OutOfService property value
0: The value is not output.
1: The value is output.
PulseDirectInput A parameter for an Accumulator object and a Keiryo object.
Set whether to store a calculated pulse counter value to a PresentValue property.
0: The value is stored after calculation (Page 282 When a PulseDirectInput is 0)
1: The value is stored without any calculation (32-bit unsigned integer).
RoundOffFlag Set whether to round off the value written to the PresentValue of an AnalogOutput object or
AnalogValue object when outputting the value to the buffer memory.
To round off the value, set the target AnalogOutput object or AnalogValue object to perform data
conversion in advance.
0: The value is not rounded off.
1: The value is rounded off.
*1 For the change of the OutOfService property, refer to the following section.
Page 120 OutOfService property
*2 For an Accumulator object, when '1' is set to "PulseDirectInput", an Event notification cannot be sent. To send an Event notification, set
'0'. (Page 184 Accumulator object)
