Arguments • type
The type of the FINS command. 0 means FINS 0101, read memory
from remote FINS server. 1 means FINS 0102, write memory to the
remote server.
• network
The destination network. For more details, see the Communication
Commands Reference Manual, cat. num. W342-E1, Section 3.
• node
The node of the destination FINS server. For more details, see the
Communication Commands Reference Manual, cat. num. W342-E1,
Section 3.
• unit
The unit number of the destination FINS server. For more details,
see the Communication Commands Reference Manual, cat. num.
W342-E1, Section 3.
• remote_area
The area of memory accessed on the destination FINS server.
Range: 128..255. Note that this area must be one of the following
values if the destination is another Trajexia system: 0xB0: Integer
VR value; 0xF0: float VR value; 0x82: Integer TABLE value; 0xC2:
float TABLE value.
• remote_offset
The memory offset on the destination FINS server. Range: 0..65535.
Note that this range will be more limited to the maximum TABLE or
VR addresses if the destination is another Trajexia system.
• length
The number of items to be transferred. The range will depend upon
the FINS frame length and the capabilities of the client and remote
servers. The range for a Trajexia system is from 1 to 700 integer val-
ues, or 1 to 350 floating point values.
• local_area
The local (source) memory area. Note that this area must be one of
the following values: 0x00: Integer VR value; 0x01: Integer TABLE
value; 0x02 : float TABLE value.
• local_offset
The offset of the first value in the local (source) memory area. The
range depends upon the VR or TABLE array size and value for the
length argument.
• timeout
The number of milliseconds to wait for a response from the destina-
tion FINS server, before timing out.
Note: Be aware that data types from both remote_area and local_area
have to match (both floating point or both integers).
Example FINS_COMMS(0, 0, 0, 0, $82, 1000, 20, 0, 500, 5000)
This command reads 20 words ( length =20) of DM PLC memory area
( remote_area =$82), starting from DM1000 ( remote_offset =1000), and
writes it in the CJ1W-MCH72 VR memory in integer format
(
local_area =0), starting from VR(500) ( local_offset =500). Thus, values
in PLC memory range DM1000 to DM1019 are placed in CJ1W-MCH72
memory VR(500) to VR(519). The timeout is set to 5 seconds.
