This section describes all of the FL-net module setting procedures. For details about message transfers,
the communication management area, and the SEND/RECEIVE function, see the respective chapters.
1 1 1 1 1 Specify a parameter area See Chapter 12.
A parameter area is allocated within the control module.
- When the JW20H, JW30H, or J-board is used for a PC, set the parameter area in accordance
with the set value of the module No. switch.
- When the JW50H/70H/100H is used for host PC, set switch SW3 on the JW-50FL.
2 2 2 2 2 Enter basic data
Enter basic data (node number, token monitor interval, and minimum separation of frames) in the
parameter area (addresses 00 to 05
(8)
).
3 3 3 3 3 Settings related to cyclic transfers
1) Enter the top address for the common memory areas (area 1 and 2)
- The data memory area (see pages 8-4 to 8-6) in which a common memory area can be
assigned in the PC varies with the model of the module installed in the PC.
- Enter the top addresses for area 1 and area 2 at parameter addresses 20 to 26
(8)
as word
addresses (see pages 8-7 to 8-12).
2) Enter the send area address for this node
- Enter the send area parameters for this node (top address and data length) for areas 1 and
2 at addresses 10 to 17
(8)
. Enter a word address (page 8-7 to 8-12) for the top address.
4 4 4 4 4 Settings related to message transfers See Chapter 9 (page 9-2).
When you will not be using the client function in the messages that are sent, this setting is not
required.
1) Set the buffer area for transmitted messages
Enter the top address of the transmission buffer, and this area (address +0000 to 4055
(8)
:
2094 bytes) will also be set. Enter the top address at parameter addresses 34 to 36
(8)
.
2) Enable use of the transmission buffer
Enable/disable the use of this buffer for each message. Use parameter address 37
(8)
.
5 5 5 5 5 Assign the communication management area See Chapter 10 (page 10-1).
Enter the top address of the communication management area, and the areas (address +000 to
