(1) Return code
The execution result of FUN200 command is set.
Completed without error -> = H0000
Completed with error -> != H0000
(2) System area
This area is used by system execution when FUN200
command is executed. Don’t use this area by user.
(3) Control type (“With hand shaking” is supported.)
H0001:The request to get Ethernet parameters from this
module
H0002: Don’t set this value.
H0003:The request to put Ethernet parameters to this
module
H0004 to HFFFF: Don’t set these value.

The area inhibited to set by user
(8) Starting execution flag
When to start sending or receiving with FUN200
command, please set “1” by user program.
This bit will be reset by system execution when the
sending or receiving is completed.
(9) The completion flag without error
This bit will be set to “1” when the sending or receiving
by FUN200 command is completed without error. This
will be reset by system when FUN200 start to execution.
(10) The completion flag with error
This bit will be set to “1” when the sending or receiving
by FUN200 command is completed with error. This will
be reset by system when FUN200 start to execution.
Unit No. : Always “0” is required.
Slot No. : Following value is required.
[For EH-CPU516/548] One of 0 to 7.
[For other EH-CPUs] One of 0 to 2.
The position of word : Always “0” is required
(5) Control bit I/O No. of starting sending or receiving
The actual address value of R, L and M which has the
starting I/O No. of the sending or receiving control bit area
should be set using ADRIO command.
(6) Starting I/O No. of Destination (or Source)
The actual address value of WR, WL and WM which has
the starting I/O No. of the source or destination area
should be set using ADRIO command.
(7) Size
The size of using area for sending or receiving should be
set. For this module, maximum size is 55 words.
