Name
Operation
H:Host link
Baud rate
Designate 1200, 2400, 4800, 9600, or 19200 bps.
(Default: 9600 bps)
Stop bits
Designate either 1 stop bit or 2 stop bits.
(Default: 2 stop bits)
Parity
Designate even, odd, or no parity.
(Default: Even parity)
Data length
(Data bits)
Designate either 7-bit or 8-bit data.
(Default: 7-bit data)
Unit number
Designate the unit number between 00 and 31. The unit number must not be the
same as the unit number of another node in an RS-422 host link. Changes to this
setting are effective immediately.
(Default: 00)
I:CPU bus link
Designate whether or not CPU bus links are used. CPU bus links are used
between BASIC Units only. The CPU bus link service interval is comparable to
the cycle time. Changes to this setting are effective immediately.
(Default: Don’t use CPU bus link)
J:Scheduled interrupt interval
Scheduled interrupts cannot be processed in CVM1D PCs.
K:1st Rack addr
Designate the first CIO words allocated to the CPU, Expansion CPU, and
Expansion I/O Rack. The first word can be set between 0 and 511. Do not allow
word allocations to overlap. Racks without a designated first word will be
allocated words automatically beginning from CIO 0000. Perform the Create I/O
Table or Change I/O Table operation or turn the power off and on after changing
this setting.
(Default: Automatic allocation by rack number beginning from CIO 0000)
L:Group 1,2 1st addr
Designate the first words between CIO 0000 and CIO 0999 for each SYSMAC
BUS/2 group-1 and group-2 Masters. The default first word will be used for
Masters without a designated first word. Perform the Create I/O Table or Change
I/O Table operation or turn the power off and on after changing this setting.
(Default: See the table on page 7-3 for details.)
M:Trans I/O addr
Designate the first word between CIO 0000 and CIO 2555 for each Master for
SYSMAC BUS I/O Terminals. Do not designate any bits that are in the hold area.
Outputs on I/O Terminals will remain on after program execution stops if they are
in the hold area.
The default first word will be used for Masters without a designated first word.
This setting does not change the Slave address. Perform the Create I/O Table or
Change I/O Table operation or turn the power off and on after changing this
setting.
(Default: 32 words per I/O Terminal starting from CIO 2300)
N:Group 3, RT 1st addr
Designate the first word for each SYSMAC BUS/2 group-3 Slave between CIO
0000 and CIO 0999 and for each SYSMAC BUS Slave Rack between CIO 0000
and CIO 2555.
Do not designate any bits that are in the hold area. Outputs on Slaves will remain
on after program execution stops if they are in the hold area.
The default first word will be used for Slaves without a designated first word.
Perform the Create I/O Table or Change I/O Table operation or turn the power off
and on after changing this setting.
(Default: See the table on page 7-3 for details.)
O:CV-SIOU 1st addr
Not used.
P:Power break
This setting is fixed at 0 ms (no momentary power interruptions) in CVM1D PCs.
Q:Cycle time
Set the minimum cycle time to between 0 and 32,000 ms. If the actual cycle time
is less than the set cycle time, execution will be halted until the set cycle time
elapses before the next cycle is executed. If the actual cycle time exceeds the set
cycle time, the setting is ignored and the next cycle is executed when the current
cycle is complete. Changes to this setting are effective immediately.
The actual cycle time might vary 3 to 4 ms from the set cycle time.
(Default: Variable cycle)
