<Effective setting range for station information>
Station number: Set the station number 1 to 7F (hexadecimal) allocated to the sub-station
(IR.Station).
Refresh cycle monitor time: Set the refresh cycle time 0 to 65535 (decimal) of the sub-
Station type: Select "AUTO" or "MANUAL" as the station type of the sub-station. When
"AUTO" is selected, set the I/O area. (Slot does not need to be set but details
cannot be set.)
When "MANUAL" is selected, I/O area does not need to be set but Slot must be
set. (The slot information including distinction between analog and digital and
address/size of I/O area can be set in detail.)
I/O area: Input byte and Output byte cannot be set to 0. However, you may set either Input
byte or Output byte to 0. The total number of input bytes and output bytes cannot
exceed /100 at setting. The I/O area must not be set doubly between stations.
Set it without duplication.
Input byte: Set the number of bytes of the input module. The setting range is /0 to /100
(hexadecimal, "/" input not required).
Input address: Set the beginning address to be allocated to the input module. For
addresses that can be set, see Table 4-2.
Output byte: Set the number of bytes of the output module. The setting range is /0 to /100
(hexadecimal, "/" input not required).
Output address: Set the beginning address to be allocated to the input module. For
addresses that can be set, see Table 4-2.
Analog mode: Select "Asynchronous" or "Synchronous." When "Synchronous" is selected,
analog value input/output processing for the station side (IR.Station) is
performed with the input/output request timing from the master side
(IR.LINK).
When "Asynchronous" is selected, analog value input/output processing is
performed regardless of the input/output request timing from the master side
(the processing is performed according to the idle time of the station side).
station. The setting unit is 10 ms. When 0 is specified,
refresh cycle monitoring is not performed. The set point
should be 5 times or more as large as the set point of refresh
cycle.
