Operating Level Setting to “$0810” specifies operating level #0; setting to “$1810” specifies oper-
ating level #1.
Number of Bytes to Send Specifies the number of bytes of data to be transmitted from the FINS command
code onwards, within a range of 2 to 2,000 ($2 to 7D0).
Number of Bytes to Receive Specifies the number of bytes of response data (from the FINS command code
onwards), within a range of 4 to 2,000 ($4 to 7D0), to be stored beginning with
the the response data storage word.
Destination Network Address Specifies the destination network address within a range of 0 to 127 ($0 to 7F).
Set to 00 when transmitting to a Unit in the local network.
Destination Node Number Specifies, within a range of 0 to 127 ($0 to 7F), the destination node number in
the network set by the destination network address. To broadcast within that net-
work, set the destination node number to FF. Set to 00 when transmitting to a
local node in the local network.
Destination Unit Address Sets the device or Unit where the command is to be sent. To send the command
to the Programmable Controller, set the destination unit address to 00. To send
to a Special I/O Unit, set a value ($10 to 1F) with $10 added to the unit number
($0 to F). The unit number of the PC Card Unit is 0 (with a unit address of $10). If
the destination unit address is set to FE, the command will be sent to the Com-
munications Unit corresponding to the destination node number.
Set the network to 0, node to 0, and Unit to $10 when sending to the PC Card Unit
in the local node.
Response Request Bit This bit is normally set to OFF (0: Request response). If no response is required,
set the bit to ON (1: Don’t request response).
Number of Retries Specifies the number of retries to be performed if a response is not returned fol-
lowing execution of the CMCR instruction. Any number from 0 to 15 ($0 to F) can
be set.
Response Monitor Time The response monitor time (i.e., the timeout time) can be set from 0 to 65,535 ($0
to FFFF), in units of 110 ms. If the default setting of “0” is specified, the response
monitoring time will be 2.2 s.
The response monitor time setting is only valid when the response request bit is
set to OFF (0: Request response).
Note If more than the number of bytes to receive is received, the bytes over the set
number will be discarded. If fewer bytes are received, the data will be stored in
the specified area and the data in the remainder of that area will be unchanged.
9-3-3 Range of Control Data
The permissible ranges of control data are as follows:
Item Value
Number of bytes to send
(see note 1.) $0002 to 07D0 (2 to 2,000 bytes) (after FINS command code)
Number of bytes to receive $0004 to 07D0 (4 to 2,000 bytes)
Destination network address $00: To the local network
$01 to 7F (1 to 127): To a designated network
Destination node number $00: To the local node
$01 to 7F (1 to 127): To a designated node
Destination unit address $00: PC
$10 to 1F: CPU Bus Unit (unit number: 0 to F, respectively)
Response request bit (see note 2.) $0 (OFF): Request response
$1 (ON):
Don’t request response
Number of retries $0 to F (0 to 15)
Response monitor time 2.2 s (default)
$0001 to FFFF:
Units of 110 ms
